Jarmulnek Common Carrier, Satellite Radio Branch Dear Mr. Caton: COMSAT General Corporation ("COMGEN"), pursuant to Section 25.119 of the Commission‘s Rules, hereby requests an extension of Special Temporary Authority to operate the COMSTAR D—4 satellite (K§8—29) at 76° W.L. using the COMSAT Maneuver, from October 15, 1994 ito April 15, 1995. All operation of the satellite will be consistent with the Commission‘s previous grants of Special Temporary Authority and COMGEN will submit reports evaluating satellite operations during the period of Special Temporary Authority. The current orbital inclination of the D—4 is approximately 7.7 degrees. To COMGEN‘s knowledge, there is no other use planned for 76° W.L. during the period covered by this Request. COMGEN continues to successfully operate the COMSTAR D—4 using the COMSAT Maneuver and, thereby, has extended significantly its useful life. During its extended lifetime, no adjacent satellite interference has been observed in either space or ground seqgment with satellites spaced two degrees apart. Continued operation using the COMSAT Maneuver is anticipated to extend the useful life of the satellite at least another five years. Grant of this request for Special Temporary Authority is in the public interest because it will permit COMGEN to meet commercial demand for satellite service over the COMSTAR D—4 satellite. At present, COMGEN is providing its customer, COMSAT Mobile Communications ("CMC"), with space segment facilities to conduct an experiment which will help to determine the viability

COMGEN hereby certifies that neither it, its officers and directors, nor any party with a five percent or greater interest in this request for special temporary authorization are subject to a denial of the federal benefits requested herein pursuant to section 5301 of the Anti—Drug Abuse Act of 1988, 21 U.S.C. § 853 (a) .
