全球卫星导航系统中，地面监测站和主控站通信传输容易受到宽带和窄带干扰的影响，导致卫星导航系统精确性和完好性降低。分析研究利用扩频增益抑制宽带干扰和利用陷波滤波器抑制窄带干扰，解决地面监测站和主控站站间通信抗宽带和窄带干扰问题，为增强卫星导航系统精确性和完好性提供了保障。
全毬衛星導航繫統中，地麵鑑測站和主控站通信傳輸容易受到寬帶和窄帶榦擾的影響，導緻衛星導航繫統精確性和完好性降低。分析研究利用擴頻增益抑製寬帶榦擾和利用陷波濾波器抑製窄帶榦擾，解決地麵鑑測站和主控站站間通信抗寬帶和窄帶榦擾問題，為增彊衛星導航繫統精確性和完好性提供瞭保障。

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 .
