以多径信号动态生成理论与多径效应误差影响理论相结合,针对北斗卫星导航系统所观测到的GEO卫星和IGSO卫星导航信号的伪距误差波动现象进行了研究,通过建立多种不同动态卫星的运动模型和镜面反射多径效应模型,实现了对卫星多径信号的动态误差模拟,对包括GEO、IGSO及MEO在内的不同动态卫星所产生的多径信号对伪距和载波相位测量造成的误差影响进行了理论分析和仿真研究。仿真实验结果与实际观测结果具有相似性,对最终揭示北斗系统GEO及IGSO卫星导航信号的伪距波动误差现象的形成机理提供了新的依据和参考。
Based on the theories of dynamic generation of multipath signal and theory of multipath effect error, the phenomenon of pseudorange error fluctuation of GEO satellite and IGSO satellite navigation signal observed by Beidou satellite navigation system was studied. By establishing a variety of dynamic satellites And the specular reflection multipath effect model to simulate the dynamic error of satellite multipath signals. The measurement of pseudorange and carrier phase caused by multipath signals generated by different dynamic satellites including GEO, IGSO and MEO The error of theoretical analysis and simulation studies. The results of simulations are similar to the actual observations and provide a new basis and reference for revealing the formation mechanism of pseudo-range fluctuation error phenomenon of Beidou system GEO and IGSO satellite navigation signals finally.
