“宽带填隙卫星系统”是一种过渡系统,是现役的“国防卫星通信系统”和“全球广播系统”向已计划的“先进宽带系统”过渡的桥梁。“先进宽带系统”是一种高容量战术通信系统,首颗卫星预定于2008年发射,可同时起到军用通信卫星和商用租赁卫星的作用。“宽带填隙卫星系统”将由3颗波音702卫星组成,首颗卫星定于2004年初发射,其余2颗将于2005年发射。该系统可以为固定和移动的战术用户提供高出目前10倍的带宽,且覆盖面更广、使用灵活性更高。
The “Broadband Gap Satellite System” is a transitional system that serves as a bridge between the active “defense satellite communications systems” and “global broadcasting systems” to the planned “advanced broadband systems.” The “Advanced Broadband System” is a high-capacity tactical communications system. The first satellite, scheduled for launch in 2008, serves as both a military communications satellite and a commercial rental satellite. The “Wideband Gap Satellite System” will consist of three Boeing 702 satellites, the first of which will be launched in early 2004 and the remaining two to be launched in 2005. The system can provide fixed and mobile tactical users 10 times higher than the current bandwidth, and coverage of a wider, more flexible use.
