Accurate DOD Measurement Using Ranging Tone of China CE2
Radiometric interferometry is one of the main tools in support of spacecraft navigation.Because it does not lose sensitivity to spacecraft declination when the spacecraft is near earths equatorial plane,as is the case for Doppler tracking.As a working mode,DOD measurement can acquire differential doppler information which is an important observation value used for orbit determination.To perform DOD tracking,the spacecraft needs to transmit high frequency sinewave tone which is usually specially designed.In this paper,we discussed algorithm of DOD measurement using traditional ranging tones.And experiment was performed with ranging tone of China CE2,data was recorded with baseline which is combined with Shanghai station and Beijing station.Theoretical analysis testifies high accuracy of our algorithm.
