摘要
GPS高精度定位结果、原始多普勒频移观测量 ,以及由载波相位中心差分而获得的多普勒频移观测值 ,它们都可以用来获得高精度的速度测量结果。主要从测速精度方面 ,对这 3种方法进行了比较 。
The precise velocity can be derived respectively with precise positioning results, receiver raw Doppler measurements and carrier phase derived Doppler measurements. A comparison between those approaches is made on the accuracy of velocity determination. A numerical example shows the difference between those approaches.
