Statistical Orbit Determination for Geostationary and Geosynchronous Satellite Orbits in BeiDou Constellation: A Simulation Study

Statistical Orbit Determination techniques are used to find satellite positions for various navigation applications. The present paper reports the simulation study of the statistical orbit determination algorithm developed for geostationary and geosynchronous orbits for BeiDou constellation. BeiDou Navigation Satellite System (BDS) space constellation is composed of geostationary earth orbit (GEO), medium earth orbit (MEO) and inclined geosynchronous satellite orbit (IGSO). However, predicting the orbital parameters for geostationary earth orbits with zero inclination and for geosynchronous satellite orbits (GSO) with small inclination angle and small eccentricity is a challenging task [1]. Thus this paper is focused on mainly satellite orbit determination techniques for GEO and GSO orbits in the BDS.
