Space–Ground Joint Support Method in Autonomous Orbit Determination of BeiDou Satellites

Remote Sensing
When relying exclusively on inter-satellite links for autonomous orbit determination, it cannot suppress or eliminate the constellation overall rotation, rendering it incapable of determining its spatial orientation relative to terrestrial and celestial ...
