摘要
Abstract
In global navigation satellite system (GNSS ) ,communication interferences between monitoring station and master control station includes broadband interference (mul-tiple access interference generally ) and narrow band interference .T his paper studied on anti-interference technology of stations communication ,and broadband and narrow band interfer-ences were respectively dealt by using spread spectrum gain and notch filter .Simulation ex-periments show that ,using the method proposed in this paper ,stations communication can stand 30-channel multiple access interference and at least 45 dBc narrow band interference .关键词
