低高度角卫星信号对提高对流层估计精度的影响分析

摘要

The influence of low-elevation satellite signals on the resolution accuracy was analysed by use of the Bernese software to calculate tropospheric refraction error and the positioning of the elevation error under different satellite elevation angles. It is concluded that with cutoff elevation angle of 5 degree the good accuracy can be reached.%分析低高度角卫星信号对解算精度的影响,运用Bernese软件计算了不同卫星高度角下对流层折射偏差及对高程误差的影响,得出结论为5°截止卫星高度角能获得更好的对流层估算精度和高程定位精度.
