The Commission, as part of its continuing effort to reduce paperwork burdens, invites the general public and the Office of Management and Budget to comment on the information collection requirements contained in this document, as required by the Paperwork Reduction Act of 1995. In addition, pursuant to the Small Business Paperwork Relief Act of 2002, we seek specific comment on how we might further reduce the information collection burden for small business concerns with fewer than 25 employees.
Synopsis
In this NPRM, we propose revisions to certain of the Commission's rules and policies governing satellite services, prompted by a planned new generation of large NGSO FSS systems. We propose to update, clarify, and streamline our rules to facilitate the deployment of NGSO FSS systems, which have the capability to provide services, including Internet access, to underserved communities worldwide. We also propose to update certain rules governing operation of FSS space stations in the geostationary-satellite orbit (GSO) to enable greater operational flexibility.
Ka-Band Plan
Proposal Overview. In light of decisions waiving the plan for the Ka-band, or the 17.7-20.2 GHz and 27.5-30 GHz bands, and to promote more flexible use of the spectrum, we propose to reinstate certain secondary FSS use in the 17.8-20.2 GHz band and to allow new FSS operations in the 19.3-19.4 GHz, 19.6-19.7 GHz, and 29.3-29.5 GHz bands. This proposal would codify existing practices and formally enable the spectrum use proposed by NGSO FSS broadband constellations currently pending before the Commission. It would further make available for FSS systems spectrum currently designated for, but never used by, NGSO mobile-satellite service (MSS) feeder links.
17.8-18.3 GHz. We propose to create a new secondary allocation to the FSS in the 17.8-18.3 GHz band, subject to protections for the primary fixed service (FS). We anticipate that the power flux-density (PFD) limits established by the International Telecommunication Union (ITU) for protection of the FS by the FSS in the 17.7-18.3 GHz band are also sufficient to protect U.S. terrestrial fixed users, without generally requiring coordination. This has long been the case in the 3700-4200 MHz band, for example, in which FSS space stations operate on a co-primary basis with FS terrestrial stations, are not typically coordinated with terrestrial operators, and are subject to ITU PFD limits codified in 47 CFR 25.208(a). And the United States participated actively in the development of ITU PFD limits in the 17.8-18.3 GHz band, with input from U.S. terrestrial operators.
Thus, we are no longer concerned about coordination and delay concerns that the Commission expressed in 2000. The Commission did not discuss the adequacy of any PFD limits in this context. And, both NGSO FSS and GSO FSS systems have been successfully authorized to operate in this band by waiver on an unprotected, non-interference basis with respect to the FS. We also note that WorldVu Satellites Limited, d/b/a OneWeb, has filed a petition for declaratory ruling to access the U.S. market in the 17.8-18.6 GHz band using its proposed system of 720 NGSO satellites. Accordingly, and to promote additional operational flexibility, we propose to adopt a secondary allocation to the FSS (space-
Page 3260
to-Earth) in the 17.8-18.3 GHz band currently designated solely for the FS. Both GSO FSS and NGSO FSS operations would be permitted under this secondary FSS allocation. Non-Federal FSS operations would also be secondary to primary Federal FSS operations in this band. We intend to limit this allocation to individually licensed earth stations, which are more likely than ubiquitously deployed user terminals to be able to operate successfully on an unprotected basis with respect to primary FS stations. We also propose to include in our rules the international PFD limits on space stations in this band. Finally, to promote compatibility among FSS systems, we propose to authorize NGSO FSS systems in this band only on an unprotected, non-interference basis with respect to GSO FSS networks. We seek comment on these proposals. As indicated above, we anticipate that PFD limits established by the ITU, with significant involvement of the United States, will be adequate to protect U.S. fixed users from interference. However, we seek comment on these PFD limits. In the unlikely event that harmful interference did occur to an FS station, we expect that the FS operator would attempt to locate and contact the source of the interference, or seek assistance from the Commission. We seek comment on this issue.
18.3-18.6 GHz and 19.7-20.2 GHz. We also propose to allow NGSO FSS systems to operate on an unprotected basis with respect to GSO FSS networks in the 18.3-18.6 GHz and 19.7-20.2 GHz bands, subject to limits on equivalent power flux-density (EPFD) to ensure protection of GSO FSS networks, as explained below. We do not propose to extend NGSO FSS operation to the 18.6-18.8 GHz band, in which GSO FSS networks are also currently designated co-primary, due to concerns of protection for the coequal Earth exploration-satellite service (passive) and the space research service (passive). As we concluded for operations in the 10.7-
14.5 GHz band, which is available for licensing of both GSO and NGSO FSS systems, we anticipate that compliance with EPFD limits applicable internationally will be sufficient to protect GSO FSS networks from unacceptable interference, by generally limiting NGSO FSS operations near the geostationary orbit. Permitting NGSO FSS operations in the 18.3-18.6 GHz and 19.7-20.2 GHz bands would also be consistent with waivers issued on delegated authority.
18.8-19.3 GHz. In addition, we propose to allow GSO FSS operation in the 18.8-19.3 GHz downlink band on an unprotected, non-interference basis with respect to NGSO FSS systems, consistent with Bureau waivers and matching the current secondary GSO FSS designation in the paired 28.6-29.1 GHz uplink band. Because NGSO FSS systems would not be required to alter their operations to accommodate any GSO FSS operations in this band, we do not believe this allowance for GSO FSS would prove burdensome to NGSO FSS systems, but we seek comment on such burdens.
18.8-19.3 GHz and 28.6-29.1 GHz. Internationally, these bands are allocated to the FSS on a primary basis. GSO satellite networks and NGSO systems in these bands are subject to coordination, and No. 22.2 of the ITU Radio Regulations does not apply. This rule provides that, regardless of their ITU filing dates, NGSO systems must not cause unacceptable interference to and, unless otherwise specified in the Radio Regulations, must not claim protection from GSO FSS and GSO broadcasting-satellite service (BSS) networks operating in accordance with the Radio Regulations. We request comment on the possibility of giving GSO operations co-primary status with NGSO operations in these bands, as opposed to the secondary designation already existing in the 28.6-29.1 GHz band and our proposal above for the 18.8-19.3 GHz band. We seek comment on any potential difficulties that this approach might raise, particularly since our rules separately address GSO-like applications and NGSO-like applications, but do not provide a mechanism for us to consider an application of one type (GSO-like or NGSO-like) vis-agrave-vis previous applications or authorizations of the other type in the bands 18.8-19.3 GHz and 28.6-29.1 GHz. Significantly, in these bands NGSO-like operations do not have to meet EPFD limits in order to ensure the protection of GSO-like operations.
19.3-19.4 GHz, 19.6-19.7 GHz, and 29.3-29.5 GHz. To facilitate satellite use of the bands, we propose to permit both GSO and NGSO FSS systems to operate in the 19.3-19.4 GHz, 19.6-19.7 GHz, and 29.3-29.5 GHz bands currently designated for, but unused by, NGSO MSS feeder links. We propose to authorize NGSO FSS systems on an unprotected, non-
interference basis with respect to GSO FSS networks in these bands. In the 19.3-19.4 GHz and 19.6-19.7 GHz bands, which are shared on a co-
primary basis with terrestrial services, any FSS earth stations would be individually licensed and coordinated with terrestrial stations. Existing terrestrial operations in these bands would not have to protect any new FSS deployment under general first-come, first-served coordination procedures. PFD limits are already in place to protect such terrestrial operations from downlink interference. Further, we anticipate that new stations in the FS and the FSS will be compatible in these bands through coordination of the specific operating parameters of each station, FS or FSS, at the time of licensing. We seek comment on this proposal, including relevant technical analyses regarding coordination parameters for new individually licensed earth stations and future FS stations.
Codification. For clarity, we propose at this time to codify the Ka-band Plan's satellite designations into footnotes to the U.S. Table of Frequency Allocations, 47 CFR 2.106. In doing so, we propose to specify that, in the 27.5-28.35 GHz band, NGSO FSS systems must operate on an unprotected, non-interference basis with respect to GSO FSS networks. This treatment would promote compatibility between the two system designs and is consistent with our proposals in most shared GSO-
NGSO FSS bands. Additionally, while the MSS is not designated in the Commission's Ka-band Plan, we do not propose to remove the allocations for this service in the 19.7-20.2 GHz and 29.5-30 GHz bands. We also propose to remove duplicative notes in 47 CFR 25.202(a)(1), except with respect to the Commission's recent decision regarding the 27.5-28.35 GHz band in the Spectrum Frontiers proceeding. Similarly, we propose to incorporate into footnotes in the Table the remaining frequency-use restrictions in 47 CFR 25.202(a)(1) that were not recently amended in the Commission's Spectrum Frontiers proceeding. However, we propose to specify the limitation on NGSO FSS deployment in the 10.7-11.7 GHz and 12.75-13.25 GHz bands as to individually licensed earth stations only, rather than to gateway earth stations only as currently prescribed. This would be consistent both with our proposal for the 17.8-18.3 GHz band and with the Commission's recent decision regarding the shared 27.5-28.35 GHz band in the Spectrum Frontiers proceeding. In addition, rather than attempt to reproduce in 47 CFR 25.202(a)(1) all of the frequency bands available for FSS, which are already stated completely in the Table of Frequency Allocations in 47 CFR 2.106, we propose to use this paragraph only to note the restrictions on FSS not codified in the Table.
PFD Limits in 17.7-19.7 GHz for GSO FSS Space Stations. Section 25.208(c)
Page 3261
contains PFD limits on emissions from space stations in, among others, the following frequency bands: 18.3-18.8 GHz and 19.3-19.7 GHz. In addition, 47 CFR 25.208(e) contains PFD limits on emissions by NGSO FSS space stations in the 18.8-19.3 GHz band. Since we are proposing changes to the U.S. Table of Frequency Allocations that will allow the operation of GSO FSS and/or NGSO FSS space stations in frequency bands where such operation was not previously contemplated, we propose to extend the applicability of PFD limits to these frequency bands. Accordingly, we propose to make the limits in 47 CFR 25.208(c) applicable to GSO FSS space stations in the frequency bands 17.7-19.7 GHz and to all space stations in the bands 22.55-23.55 GHz and 24.45-
24.75 GHz. These limits have already been applied in portions of the 17.7-19.7 GHz band when granting authorizations for operation in this band through waivers.
PFD Limits for NGSO FSS Space Stations. We also propose to make the limits in 47 CFR 25.208(e) applicable to NGSO FSS space stations in the frequency bands 17.8-18.6 GHz and 18.8-19.7 GHz. We recognize, however, that these limits were derived for constellations up to a certain number of satellites and may not be appropriate for some of the large NGSO FSS constellations being currently proposed. The interference produced by an NGSO FSS constellation to a terrestrial station is time-
varying and, for that reason, the protection of such a station would be better ensured through the establishment of an EPFD limit. We invite comment on this point and on what would be an appropriate EPFD for the protection of a terrestrial station in the frequency bands under consideration. As an alternative, and until such EPFD limit can be developed, we propose that an NGSO FSS constellation be deemed as having met the requirements in 47 CFR 25.208(e) if the aggregate PFD produced by the whole constellation at any point in the Earth's surface does not exceed -115 (dBW/m\2\)/MHz. We invite comments on this proposal.
Other. As NGSO FSS systems deploy in different frequency bands, it is important to consider how these systems can share spectrum with other non-satellite systems. In this respect, we request comments on any other emerging uses, technologies, or platforms that should be taken into account as additional NGSO uses occur. Would the rules proposed in this Notice preclude in any way other uses of this spectrum or hinder future sharing with other services? Are there additional technical rules or other means by which we can facilitate additional sharing in these bands?
EPFD Limits
Ka-band. While the Commission has not previously included in its rules the Ka-band EPFD limits found in Article 22 of the ITU Radio Regulations, NGSO FSS applicants in these bands have nonetheless demonstrated compliance with the limits when seeking to operate on a non-interference basis vis-agrave-vis GSO FSS networks. The International Bureau has approved such operations on the basis of these showings. Similarly, we expect that compliance with the Article 22 EPFD limits will be sufficient for NGSO FSS systems to protect GSO FSS networks in the 17.8-18.6 GHz, 19.7-20.2 GHz, 27.5-28.35 GHz, and 29.5-
30 GHz bands, as the U.S. GSO FSS community participated actively in their development. Accordingly, to provide greater certainty regarding the compatibility of NGSO FSS and GSO FSS operations, we propose to require NGSO FSS applicants in these bands to demonstrate conformance with applicable EPFD limits in the same manner that NGSO FSS applicants must for operation in the 10.7-14.5 GHz band. We intend that compliance with EPFD limits in the Ka-band would satisfy any obligation on an NGSO FSS system to operate on a non-interference basis with respect to a GSO FSS network. In addition, we propose to incorporate EPFD limits on inter-satellite emissions from NGSO FSS space stations into GSO FSS space stations, which are currently found in Article 22 but omitted from our rules. We also propose to extend relevant Article 22 EPFD limits to the 19.3-19.4 GHz, 19.6-19.7 GHz, and 29.3-29.5 GHz bands in which we are proposing to allow new NGSO FSS operations on an unprotected, non-interference basis with respect to GSO FSS networks.
Consolidation. In adding these Ka-band EPFD rules, we propose to consolidate our NGSO FSS licensing provisions for operation in the Ka-
band, currently found in 47 CFR 25.145, into the licensing rules for NGSO FSS operation in the 10.7-14.5 GHz band, set forth in 47 CFR 25.146. In doing so, we propose to delete 47 CFR 25.145(e), similar provisions in 47 CFR 25.142(d) and 25.143(d), and the cross-references to 47 CFR 25.142(d) in 47 CFR 25.217, all of which proscribe certain exclusionary arrangements to serve foreign markets. These provisions have been superseded by section 648 of the Open-market Reorganization for the Betterment of International Telecommunications (ORBIT) Act, which contains a parallel prohibition. We also request comment on ways we might simplify 47 CFR 25.146.
NGSO-GSO Default Sharing. Finally, the first sentence of 47 CFR 25.156(d)(5) provides that, in frequency bands in which the Commission has not yet adopted sharing criteria between GSO-like and NGSO-like satellite operations, the Commission will not grant an application for NGSO-like operation after it has granted an application for GSO-like operation, or vice versa. The effect of this provision is to preclude joint NGSO-like and GSO-like use of frequency bands until the Commission has adopted formal sharing criteria between the different types of satellite operation in that band. As noted above, however, the International Bureau has approved by waiver both GSO-like and NGSO-like operations in the same Ka-band frequencies without EPFD sharing criteria yet codified in our rules. Similarly, we believe that an applicant demonstrating that it can operate compatibly with any existing operations, either through technical demonstrations or coordination, ought not be precluded from providing service to the public while the Commission initiates and conducts a rulemaking to establish formal sharing criteria. We therefore propose to delete the first sentence of 47 CFR 25.156(d)(5). We also request comment as to whether we should adopt, as a default sharing rule, a provision similar to No. 22.2 of the ITU Radio Regulations. This provision would state that, except as otherwise provided in our rules, NGSO systems must not cause unacceptable interference to, and must not claim protection from, GSO FSS networks and GSO BSS networks. For example, the 18.8-19.3 GHz and 28.6-29.1 GHz bands would be excepted from such a provision, because in these bands we require GSO FSS networks to operate on an unprotected, non-interference basis with respect to NGSO FSS systems.
Avoidance of In-line Interference
Background. The Commission has adopted a default mechanism to enable spectrum sharing among NGSO FSS systems in the 10.7-12.7 GHz, 12.75-13.25 GHz, 13.75-14.5 GHz, 18.8-19.3 GHz, and 28.6-29.1 GHz bands. Under this mechanism, an NGSO FSS system may operate throughout its authorized band except during ``in-line'' events. An ``in-line'' event occurs when satellites of different NGSO FSS systems are physically aligned with an operating earth station of one of those systems, such that the topocentric angle between the satellites is less than 10 degrees as
Page 3262
measured from the earth station. To avoid interference among the systems experiencing an in-line event, the Commission requires the affected satellite operators to divide the commonly assigned spectrum equally according to the chosen ``home'' spectrum for the duration of the in-line event, absent another sharing agreement by the operators.
Section 25.261. The avoidance of in-line interference mechanism is codified in 47 CFR 25.261. This section, however, omits the 10.7-12.7 GHz, 12.75-13.25 GHz, and 13.75-14.5 GHz bands. We propose to correct this omission. We also propose to include in 47 CFR 25.261 the bands in which we currently designate NGSO FSS operation on a secondary basis--
27.5-28.6 GHz and 29.5-30 GHz--and the bands in which we are proposing to allow NGSO FSS operation--17.8-18.6 GHz, 19.3-19.4 GHz, 19.6-20.2 GHz, and 29.3-29.5 GHz. We otherwise propose to clarify that 47 CFR 25.261 applies only to NGSO FSS systems communicating with earth stations with directional antennas. We seek comment on expanding this spectrum sharing method to NGSO FSS operations in other frequency bands, in place of the alternative procedure for assigning spectrum to NGSO satellite systems by simply dividing it equally among the qualified applicants in a processing round. In this regard, we propose to clarify in 47 CFR 25.157 that these band-splitting procedures do not apply to applications granted on the condition of compliance with the avoidance of in-line interference mechanism specified in 47 CFR 25.261. We also seek comment on any other standard for assigning spectrum.
Ephemeris Data. In order to effectuate the avoidance of in-line interference mechanism, NGSO FSS operators must know the locations of co-frequency NGSO FSS space stations to predict when in-line events will occur. Section 25.271(e) requires NGSO FSS licensees in the 10.7-
14.5 GHz band to maintain a Web site with ephemeris data for each satellite in its constellation, which facilitates coordination for this purpose. NGSO FSS licensees in the 18.8-19.3 GHz and 28.6-29.1 GHz bands must also share ephemeris data. Accordingly, we propose to include the 18.8-19.3 GHz and 28.6-29.1 GHz bands in 47 CFR 25.271(e), along with the portions of the Ka-band currently designated for NGSO FSS operation on a secondary basis or proposed for NGSO FSS operation in this Notice, i.e., the 17.8-18.6 GHz, 19.3-19.4 GHz, 19.6-20.2 GHz, 27.5-28.6 GHz, and 29.3-30 GHz bands. We also propose to apply this requirement explicitly to non-U.S.-licensed NGSO FSS operators that are granted market access in the United States.
We understand that satellites in the low-Earth orbit (LEO) region, i.e., the region of space at Earth altitudes below 2,000 km, that do not have station-keeping capability have experienced orbital perturbations from solar events resulting in a reduction in altitude of up to several kilometers from a single solar event. We invite comment as to whether the current ephemeris data update frequency of once every three days as required by 47 CFR 25.271(e) is appropriate for such satellites, or whether we should require more frequent updates, and if so, what the appropriate update interval would be. We also invite comment as to whether an electronic Web site bulletin board as currently required by 47 CFR 25.271(e) is the most appropriate means of making ephemeris data available, or whether another method, such as requiring active participation in the Space Data Association and/or requiring the sharing of data with the U. S. Strategic Command's Joint Space Operations Center (or any successor) might be a more effective means.
10-degree Trigger. In addition, we note that the 10-degree default separation for co-frequency NGSO FSS space station operations is based on the characteristics of satellite systems proposed around the turn of the millennium. We invite comment as to whether the separation-angle trigger should be increased or decreased to reflect current system designs.
Accommodation of Later Entrants. Finally, when authorizing NGSO FSS systems in the past, the International Bureau has required licensees to abide by the avoidance of in-line interference mechanism generally with respect to later-authorized NGSO FSS systems, unless coordination agreements are reached. To the extent that later-authorized systems increase the frequency of in-line events, or increase the number of satellite systems involved in an in-line event, such later entrants can diminish the amount of spectrum available to an existing NGSO FSS system. We invite comment on how best to balance the competing interests of encouraging new market entry and providing NGSO FSS operators certainty with respect to a minimum amount of spectrum available for their services. For example, should we specify that the avoidance of in-line interference mechanism applies only to those in-
line events among the existing grantee, O3b Limited, and any licensees and market access holders approved as a result of a processing round? In this case, an applicant requesting authority after any processing round would be required to protect existing NGSO FSS authorization holders, and would be required, during an in-line event, to cease operations on the commonly authorized spectrum.
Earth Station E.I.R.P. Density Limits
In light of the ability of the O3b NGSO FSS system to operate within existing e.i.r.p. density criteria for GSO FSS earth stations, and considering the spectrum sharing benefits of such criteria, we invite comment on adopting e.i.r.p. density limits for NGSO FSS uplink transmissions. These could be based, for example, on the limits we have prescribed for FSS earth stations transmitting to GSO space stations. Such default limits could be exceeded to the extent that higher levels are coordinated with all other NGSO FSS systems authorized in the same frequency bands. If we were to adopt e.i.r.p. density limits for NGSO FSS uplink transmissions, should we simply require a certification from applicants that they will abide by these default power limits unless higher transmission levels are appropriately coordinated? This certification requirement could be similar to certification requirements the Commission has recently adopted for GSO FSS and 17/24 GHz BSS space station operations. We also seek comment on whether, similar to our policy regarding GSO FSS space stations, there are appropriate downlink power limits and earth station receive gain criteria that we should adopt to facilitate sharing among NGSO FSS systems. We further seek comment on any other measures that should be recommended to facilitate sharing.
Milestones
Background. The Commission requires all satellites in an authorized NGSO constellation to be launched and operated within six years of grant. This milestone requirement is intended to ensure timely provision of service, and to prevent ``warehousing'' of spectrum and orbital resources. Failure to meet this requirement, incorporated as a condition of the constellation grant, renders the authorization null and void, and subjects the grantee to forfeiture of up to $5 million under the surety bond posted for the authorization.
NGSO Milestone. Operation of every space station in an authorized constellation, however, may not be necessary to provide the services proposed in the application. Additional space stations could be authorized to reduce latency or to increase capacity and reliability, for example. And while
Page 3263
failure to successfully launch and operate such additional space stations within six years might not preclude service to the public, it could, under current rules, result in automatic termination of the license. To afford operators greater flexibility with system design and implementation, we propose to modify the six-year milestone obligation for NGSO systems to require the launch and operation of a percentage of the authorized constellation sufficient to provide substantial service to the public. We tentatively conclude that 75 percent is an appropriate number for this requirement. Satisfaction of this milestone would release the operator from its surety bond obligation. Failure to operate the minimum number of space stations by this milestone, however, would result in forfeiture of the bond and an automatic reduction in the number of authorized satellites to the number actually in orbit as of the milestone date. Even under this ``keep what you use'' proposal, however, we would continue to terminate automatically the full license of a satellite system if no authorized space stations were functional in orbit as of the time of the milestone deadline. For operators that satisfy the first milestone, we propose a second milestone, nine years after grant, requiring launch and operation of the entire authorized constellation. Operators failing to complete their constellations by this second milestone date would similarly have their number of authorized space stations reduced automatically to the number deployed as of the second milestone date. We invite comment on this and any other modifications to our NGSO milestone policy.
As an alternative to specifying a percentage of the authorized constellation for an initial milestone, for example, should we require the launch and operation of a number of satellites specific to the services and constellation proposed? If so, should the applicant be required to state the minimum number of satellites necessary to provide the services it proposes? If we adopt a more flexible milestone requirement, should it be limited to large NGSO constellations, and if so what size? Should we add additional, periodic milestones, to automatically reduce the number of authorized satellites if a licensee demonstrates that it is unlikely to maintain its larger, authorized constellation size following the decommissioning of its initial deployment? We could, for example, specify that the number of authorized satellites is reduced automatically to the greatest number operated concurrently during the previous year if the licensee falls below a certain percentage of its authorized constellation. If, after satisfaction of any milestones, an NGSO licensee fails to maintain at least one operational satellite in orbit for a specified period of time, should its license be terminated automatically?
Replacements. We also propose to clarify in 47 CFR 25.164 that both GSO and NGSO replacement space stations, which must be scheduled for launch before the retirement of the space stations being replaced, are not subject to the separate milestone requirements in that section.
Geographic Coverage
The Commission requires the design of NGSO FSS systems that will operate in the 10.7-14.5 GHz, 18.8-19.3 GHz, or 28.6-29.1 GHz bands to enable service worldwide for at least 18 hours every day. This requirement is intended to foster seamless global communication networks and to maximize the use of global spectrum resources, but also prohibits certain NGSO system designs. In light of the spectrum sharing opportunities among NGSO FSS systems, and given the separate requirements for coverage of the United States already included in our rules, we propose to eliminate this global coverage requirement in order to provide operators greater flexibility to design their systems to meet market demands. We invite comment on this proposal.
Initial Regulatory Flexibility Analysis
As required by the Regulatory Flexibility Act (RFA), the Commission has prepared this Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on small entities by the policies and rules proposed in this NPRM. We request written public comments on this IRFA. Commenters must identify their comments as responses to the IRFA and must file the comments by the deadlines for comments on the Notice in the DATES section above. The Commission will send a copy of the NPRM, including this IRFA, to the Chief Counsel for Advocacy of the Small Business Administration. In addition, summaries of the Notice and IRFA will be published in the Federal Register.

Need for, and Objectives of, the Proposed Rules
The Notice seeks comment on several proposals relating to the Commission's rules and policies for satellite services, especially those concerning non-geostationary-satellite (NGSO), fixed-satellite service (FSS) systems. Adoption of the proposed changes would, among other things, provide for more flexible use of the 17.8-20.2 GHz bands for FSS; promote shared use of spectrum among NGSO FSS satellite systems; and remove unnecessary design restrictions on NGSO FSS systems.
The NPRM proposes several changes to 47 CFR parts 2 and 25. Principally, it proposes to:
(1) Allocate additional spectrum for use by FSS systems on a secondary basis in the 17.8-18.3 GHz band, subject to power flux-
density limits designed to protect primary terrestrial services.
(2) Allow additional operation of NGSO FSS systems in segments of the 17.8-20.2 GHz band within limits protective of FSS satellite systems in the geostationary-satellite orbit (GSO).
(3) Allow GSO FSS operation in the 18.8-19.3 GHz band on an unprotected, non-interference basis with regard to NGSO FSS systems, to provide additional operational flexibility.
(4) Amend the Commission's satellite milestone policies and geographic coverage rules to provide additional regulatory flexibility to operators of NGSO FSS systems.

Legal Basis
The proposed action is authorized under sections 4(i), 303, and 316 of the Communications Act of 1934, as amended, 47 U.S.C. 154(i), 303, 316.

Description and Estimate of the Number of Small Entities to Which the Proposed Rules May Apply
The RFA directs agencies to provide a description of, and, where feasible, an estimate of, the number of small entities that may be affected by adoption of proposed rules. The RFA generally defines the term ``small entity'' as having the same meaning as the terms ``small business,'' ``small organization,'' and ``small governmental jurisdiction.'' In addition, the term ``small business'' has the same meaning as the term ``small business concern'' under the Small Business Act. A small business concern is one which: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the Small Business Administration (SBA). Below, we describe and estimate the number of small entity licensees that may be affected by adoption of the proposed rules.
Page 3264
Satellite Telecommunications and All Other Telecommunications
The rules proposed in this Notice would affect some providers of satellite telecommunications services, if adopted. Satellite telecommunications service providers include satellite and earth station operators. Since 2007, the SBA has recognized two census categories for satellite telecommunications firms: ``Satellite Telecommunications'' and ``Other Telecommunications.'' Under both categories, a business is considered small if it had $32.5 million or less in annual receipts.
The first category of Satellite Telecommunications ``comprises establishments primarily engaged in providing point-to-point telecommunications services to other establishments in the telecommunications and broadcasting industries by forwarding and receiving communications signals via a system of satellites or reselling satellite telecommunications.'' For this category, Census Bureau data for 2007 show that there were a total of 512 satellite communications firms that operated for the entire year. Of this total, 482 firms had annual receipts of under $25 million.
The second category of Other Telecommunications is comprised of entities ``primarily engaged in providing specialized telecommunications services, such as satellite tracking, communications telemetry, and radar station operation. This industry also includes establishments primarily engaged in providing satellite terminal stations and associated facilities connected with one or more terrestrial systems and capable of transmitting telecommunications to, and receiving telecommunications from, satellite systems. Establishments providing Internet services or voice over Internet protocol (VoIP) services via client-supplied telecommunications connections are also included in this industry.'' For this category, Census Bureau data for 2007 show that there were a total of 2,383 firms that operated for the entire year. Of this total, 2,346 firms had annual receipts of under $25 million. We anticipate that some of these ``Other Telecommunications firms,'' which are small entities, are earth station applicants/licensees that might be affected if our proposed rule changes are adopted.
We anticipate that our proposed rule changes may have an impact on earth station and space station applicants and licensees. Space station applicants and licensees, however, rarely qualify under the definition of a small entity. Generally, space stations cost hundreds of millions of dollars to construct, launch, and operate. Consequently, we do not anticipate that any space station operators are small entities that would be affected by our proposed actions.
-
Description of Projected Reporting, Recordkeeping, and Other Compliance Requirements for Small Entities
The Notice proposes and seeks comment on several rule changes that would affect compliance requirements for earth station and space station operators. Most proposed changes, however, are directed at space station applicants and licensees. As noted above, these parties rarely qualify as small entities.
For example, we propose to allow additional uses of certain frequencies within the 17.8-20.2 GHz band, subject to compliance with power limits designed to protect other users of the bands. We also seek comment on revised or new technical standards to promote sharing among NGSO FSS systems, and ask whether we should allow entities to certify that that will comply with such resulting requirements, as a means to avoid unnecessary regulatory burdens.
We also propose modified rules for satellite system implementation to provide additional flexibility to operators. We propose to eliminate a geographic service requirement that restricts the design possibilities of certain NGSO FSS satellite systems. In total, the proposals and questions in the Notice are designed to achieve the Commission's mandate to regulate in the public interest while imposing the lowest necessary burden on all affected parties, including small entities.
-
Steps Taken To Minimize Significant Economic Impact on Small Entities, and Significant Alternatives Considered
The RFA requires an agency to describe any significant, specifically small business, alternatives that it has considered in reaching its proposed approach, which may include the following four alternatives (among others): ``(1) the establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (2) the clarification, consolidation, or simplification of compliance and reporting requirements under the rules for such small entities; (3) the use of performance rather than design standards; and (4) an exemption from coverage of the rule, or any part thereof, for such small entities.''
The Notice seeks comment from all interested parties. The Commission is aware that some of the proposals under consideration may impact small entities. Small entities are encouraged to bring to the Commission's attention any specific concerns they may have with the proposals outlined in the Notice.
The Commission expects to consider the economic impact on small entities, as identified in comments filed in response to the NPRM, in reaching its final conclusions and taking action in this proceeding.
In this NPRM, the Commission invites comment on means to minimize negative economic impacts on applicants and licensees, including small entities. For example, the Commission seeks comment on whether compliance with certain power limits could be certified to by applicants, rather than demonstrated technically, thereby reducing burdens. And the Commission proposes to relax a satellite system geographic coverage requirement, which could lessen the economic burden on applicants and licensees. Overall, the proposals in the Notice seek to increase flexibility for NGSO FSS applicants and licensees and reduce burdens, while maintaining adequate protections against interference.

Revise Sec. 25.261 to read as follows:
Sec. 25.261 Procedures for avoidance of in-line interference among NGSO FSS systems.
(a) Scope. This section applies to NGSO FSS satellite systems that communicate with earth stations with directional antennas and that operate under a Commission license or grant of U.S. market access under this part in the 10.7-12.7 GHz (space-to-Earth), 12.75-13.25 GHz (Earth-to-space), 13.75-14.5 GHz (Earth-to-space), 17.8-18.6 GHz (space-to-Earth), 18.8-19.4 GHz (space-to-Earth), 19.6-20.2 GHz (space-
to-Earth), 27.5-29.1 GHz (Earth-to-space), or 29.3-30 GHz (Earth-to-
space) bands.
(b) Definition of ``In-line event.'' For purposes of this section, an ``in-line event'' associated with a specific frequency range occurs when there is physical alignment of space stations of two or more NGSO FSS satellite systems authorized to use this frequency range with an operating earth station of one of these systems such that the angular separation between operational links of the satellite systems is less than 10deg as measured at the earth station.
(c) Default procedure. Unless otherwise coordinated pursuant to paragraph (d) of this section, NGSO FSS satellite operators experiencing an in-line event must divide their commonly assigned spectrum in accordance with the following procedure:
(1) Each of n (number of) satellite systems involved in a particular in-line event must select 1/n of the commonly assigned frequency range for its ``home'' spectrum. The selection order for each satellite system will be determined by the date that the first space station in the satellite system commences operation.
(2) The affected space station(s) of the respective satellite systems must operate only in the selected (1/n) spectrum associated with its satellite system, its home spectrum, for the duration of the in-line event.
(3) All affected space station(s) may resume operations throughout the frequency range associated with the in-line event once the angular separation between the space stations exceeds 10deg.
(d) Coordination procedure. Any coordination procedure agreed among the affected operating satellite systems, which allows operations of the satellite systems when each system's respective space stations are within the 10 degree avoidance angle associated with an in-line event, will supersede the default procedure of paragraph (c) of this section. All parties must coordinate in good faith.
