| Abstract: | 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. |
