doi:10.11947/j.AGCS.2017.20160203

Abstract

Abstract: The experimental satellite of BD navigation system has assembled inter-satellite link (ISL) payloads and has obtained the real ISL observation data. The paper presents the preprocessing method of ISL and the POD method and result for Ka only observation and the combination Ka observation with L-band. It's showed that:the radial orbit error is less than 0.5 m with Ka only observation; the radial orbit error is less than 0.3 m with the observation by combining the Ka ISL with L-band data which has improved the orbit accuracy remarkably in contrast to L-band only data; the accuracy of calibrating device delay is better than 0.1 m。

Key words: BD navigation satellite, inter-satellite link, precision orbit determination, autonomous orbit determination, device delay
