A method for realizing high-precision monitoring of satellite clock based on BeiDou's co-satellite RDSS and RNSS signals

The paper focuses the use RDSS and RNSS signal of the BeiDou satellite to realize the precision satellite clock monitoring method. This paper analyzes the frequency transfer relationship of RDSS/RNSS which is the co-satellite of BeiDou's GEO satellites, establishes the relevant frequency transfer equation, and proposes a satellite clock precision monitoring algorithm using RDSS/RNSS signals' carrier phase combination in the MCS (Master Control Station). The paper verified the method by computer simulation. Compared with the traditional pseudo-range-based method, the method has the advantages of not relying on satellite ephemeris and higher precision.
