一种适用于 GEO 卫星的多径误差抑制方法
A multipath error mitigation method used for GEO satellite
摘要
Abstract
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 weigh-ted multipath correction method was proposed ,which used multipath fading factor to monitor and dis-tinguish 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 .关键词
