Yesterday, CD Radio's (aka Sirius Satellite Radio) application to launch a new non-geostationary satellite was dismissed. The reason for dismissal was because Sirius failed to provide adequate information for the end of life disposal of the satellite. Sirius can reapply. The Commission advised Sirius to provide the following information when it resubmits its application:
First, we ask that Satellite CD Radio provide additional information concerning its post-mission disposal plans for the FM-6 satellite as part of any future filing. As part of its current application, Satellite CD Radio proposes to dispose of the FM-6 satellite at end of life by circularizing the orbital altitude of the satellite to an operational perigee of approximately 46,325 kilometers.’ In any future filing, Satellite CD Radio should confirm the inclination of the disposal orbit, as well as provide any information it has supporting the long-term stability of the disposal orbit.
Second, space station antennas in the fixed-satellite service must be designed to provide a crosspolarization isolation such that the ratio of the on axis co-polar gain to the cross-polar gain of the antenna in the assigned frequency band shall be at least 30 dB within its primary coverage area.’ Although Satellite CD Radio states in its Attachment A to its application that the cross polarization isolation of the satellite feeder link receiver antenna will exceed 30 decibels (dB) within the -3 dB gain contour of the receive frequency, this value stated as 25 dB in its schedule S filling. We request that Satellite CD Radio confirm the actual cross-polar isolation of its antenna as part of any future filing.
Update: Sirius has since refiled: Narrative, Tech Description, Technical Supplement
