Mobile-Satellite Service and Aeronautical Telemetry
By this Second Report and Order (Second R&O) the Commission reallocates the 1525-1530 MHz band to the mobile-satellite service (MSS) on a primary basis for space-to-Earth (downlink) transmissions. This action will increase the efficiency of MSS operations in the previously allocated 1530-1544 MHz band (downlink) and the 1626.5- 1645.5 MHz band (Earth-to-space, or uplink) by equalizing the amount of spectrum available in each segment. This action implements a 1992 World Administrative Radio Conference (WARC-92) spectrum allocation and facilitates international coordination for use of this spectrum.
