MSV states that its satellite will operate consistent with the requirements for inclined orbit satellites set forth in Section 25.280 of the Commission's rules. We grant MSV's request. We note, however, that granting this request creates a potential for harmful interference between MSV-1's Ku-band operations and Ku-band NGSO fixed-satellite service (FSS) satellites. Pursuant to ITU Radio Regulations, GSO satellites such as MSV-1 are protected against interference from NGSO FSS satellites operating in the same band, provided that the GSO satellite's

ICO states that its satellite will operate in compliance with the requirements for inclined orbit satellites in Section 25.280 of the Commission's rules. This proposal does not present any cause for concern. We remind ICO, however, that under the ITU Radio Regulations, operation of a GSO satellite in an allocated FSS band is entitled to protection against interference from co-frequency NGSO satellites only if the GSO satellite's north-south inclination is 4.5º or less.

Protection of operations for GSO FSS satellites inclined greater than 4.5 degrees is more difficult because inclined operations basically extend the north-south extension of the geostationary satellite orbit. However, the number of U.S. licensed satellites that continue to provide service while at inclinations greater than 4.5 degrees is extremely limited, and Section 25.280 of the Commission's Rules does not provide additional protection to GSO FSS satellites beyond that provided to GSO FSS satellites that are operating without inclination. Thus, we do not adopt specific protection requirements for GSO operations inclined beyond 4.5 degrees.

Section 25.280 is proposed to be amended in its entirety, as follows: § 25.280 Inclined Orbit Operations (a) Satellite operators may commence operation in inclined orbit mode without obtaining prior Commission authorization provided that the Commission is notified by letter within 30 days after the last north-south station keeping maneuver. The notification shall include: (1) The operator's name; (2) The date of

Our action today does not, however, alter in any way the obligation of space stations in the Fixed-Satellite Service to comply with the ±0.05° longitudinal tolerance requirements of Section 25.210(j), as amended herein. The second change proposed in the Orbital Debris Notice involved amending the text of Section 25.280 of the Commission's rules. Section 25.280 permits satellite operators in geosynchronous orbits to operate in inclined orbits without prior Commission authorization, subject to certain conditions, including notification to the Commission of such operations. The Notice proposed to amend the text of this rule by specifying that notification to the Commission must occur within 30 days after the last north-south station-keeping
