WASHINGTON D.C. 20554 News media information 202-418-0500 Fax-On-Demand 202-418-2830; Internet: http://www.fcc.gov (or ftp.fcc.gov) TTY (202) 418-2555 Friday September 21, 2007SAT-00473 Report No. Satellite Space Applications Accepted for Filing POLICY BRANCH INFORMATION The applications listed below have been found, upon initial review, to be acceptable for filing. The Commission reserves the right to return any of the applications if, upon further examination, it is determined the application is not in conformance with the Commission's rules or its policies. Consideration of each satellite application in this Public Notice may depend on the Commission's action on another satellite application earlier in the queue. Petitions, oppositions and other pleadings filed in response to this notice should conform to Section 25.154 of the Commission's rules, unless otherwise noted. 47 C.F.R. § 25.154. S2119SAT-MOD-20070911-00123 E Modification 09/11/2007 14:17:20:01300Date Filed: XM Radio Inc. XM Radio Inc. (XM) requests authority to modify three of its licensed satellites - XM-1 (Call Sign 2118), XM-2 (Call Sign S2119), and XM-3 (Call Sign S2617) - by collocating the satellites at the nominal 85º W.L. orbital location in order to ensure optimal performance of XM’s Satellite Digital Audio Radio Service (SDARS) system in the event of an outage. XM proposes to position these three satellites side-by-side within an overall station-keeping box of 0.2 degrees. XM requests authority to 1) operate XM-1 as an in-orbit spare at the 85.150° W.L. orbital location with an East-West station-keeping tolerance of ±.033°; 2) operate XM-2 as an in-orbit spare at the 85.217º W.L. orbital location with an East-West station-keeping tolerance of ±.033°; 3) operate XM-3 at the 85.083° W.L. orbital location with an East-West stationkeeping tolerance of ±.033° including continuous operation of its communications payload during the drift to that location; and 4) activate the communications payload of XM-1 and XM-2 in the event of an XM-3 or XM-4 service outage.
