Abstract

Abstract: The BeiDou coordinate system(BDCS) is the geodetic datum of the BeiDou Satellite Navigation System. After a brief description of the backgrounds, the definition of origin, scale, and orientation, and the defining and deriving constants of the reference ellipsoid of the BDCS are given. Then addressed is the first realization of the BDCS, namely, the ITRF2014 coordinates at epoch 2010.0 and velocities of 8 monitoring stations of the BeiDou system, which has been achieved by processing four-phases GPS data for a global GNSS network including the monitoring stations, and by the frame alignment and the linear regression fitting of station coordinate series. Discussions and suggestions are made about the period of re-realization of the system, the monitoring stations' overseas layout and continuously observing, the generation and distribution of precise ephemerides of BeiDou satellites, and the standardization of the BDCS. Finally, a summary concludes the paper.

Key words: The BeiDou coordinate system, BeiDou satellite navigation system, reference frame, monitoring stations
