中文摘要	针对地球静止轨道(GEO)卫星的多径效应严重影响卫星导航系统监测站业务,且多径误差的起伏变化时快时慢,及在慢变时段内多径误差保持偏移,使现有多径抑制方法的性能明显下降等问题,提出一种加权多径误差修正方法.该方法利用多径衰落因子监测、区分多径误差慢变时段和快变时段,并对不同时段的观测量加权平均,从而降低慢变区间对多径误差抑制性能的影响.同时给出了该方法的实时计算方式.仿真与实测结果显示:相比于传统多径抑制方法,该方法能够有效消除GEO卫星多径误差,使多径误差降低10%.; The multipath error for geostationary earth orbit(GEO)satellites can seriously affect the monitor station work of satellite navigation system,where the multipath error fluctuates sometimes fast and sometimes slowly.In the slow fluctuation time section,the multipath error keeps bias,which will degrade the performance of current multipath mitigation method.To solve this problem,a weighted multipath correction method was proposed,which used multipath fading factor to monitor and distinguish the fast fluctuation time section and slow fluctuation time section,and then the measurements in different sections were used by different weight to eliminate the slow fluctuation section influence on the multipath error mitigation.The real time algorithm of the proposed method was also provided.The simulation results and field test results show that the proposed method can significantly mitigate the multipath error for GEO satellite,and provide 10% more multipath error reduction compared with traditional method.
