摘要
文章介绍了GPS系统测速的基本原理和算法,并在此基础上讨论了对卫星轨道误差、对流层误差、电离层误差、载波相位噪声和星钟误差等误差源的修正算法及其对测速精度的影响。最后,通过实验测试进一步验证了高精度测速算法的可行性。
The basic principle and algorithm of velocity measurement using GPS is introduced.Correction algorithms to error source caused by orbit error,troposphere error,ionosphere error,noise of carrier phase and satellite clock bias is discussed,also with its influence to precision of velocity measurement.In the end,feasibility of this high accuracy velocity measurement algorithm has been further validated by experiment.
