摘要
通过分析卫星导航系统的定位精度和几何衰减因子随截止高度角变化情况,分析截止高度角灵敏度在提高卫星导航系统定位精度方面的重要作用。结果表明,通过合理的设计截止高度角,避免在高灵敏度的截止高度角下测量,可以改善卫星几何图形结构,同时,兼顾卫星的测距误差,提高卫星导航系统的定位精度。
By analyzing satellite navigation system positioning accuracy and geometric attenuation factor,the sensitivity of cut-off angle is analysed,which plays an important role in im proving satellite navigation system positioning accuracy.The results show that through rational design the cut-off angle to avoid the high sensitivity of the cut-off angle the measurement can improve satellite geometry structure as well as satellite ranging errors,thereby improving the positioning accuracy of the satellite navigation system.
