| Abstract: | The mathematical model of velocity determination with Doppler measurements is discussed.The effects of error sources on velocity determination are analyzed,and the accuracy of velocity determination with COMPASS using real data in static for a numerical example is preliminary studied.The results show that the accuracy of COMPASS raw Doppler measurements can be better than 0.1 m/s. |
