Satellite Licensing Procedures
American Mobile Satellite Corporation (``AMSC'') is the only U.S. mobile satellite service (``MSS'') system currently authorized to operate in the upper L-band. However, international coordination has been extremely difficult and we do not believe we will be able to secure sufficient spectrum in the upper L-band for AMSC's operations. Therefore, the Commission has proposed to assign the first 28 MHz of spectrum (14 MHz for Earth- to-space transmissions and 14 MHz for space-to-Earth transmissions) internationally coordinated in both the upper and lower portions of L- band to AMSC. This proposal will help to ensure that MSS becomes a reality in the L-band and AMSC, a licensed and partly operating satellite system, is able to provide service.
