Real-Time Precise Positioning Performance of BDS-3 PPP-B2b: Evaluation and Marine Buoy Application

This study decodes the BDS-3 PPP-B2b binary data broadcast by BDS satellites using a self-developed software decoder, RT-B2b (Real-Time PPP-B2b). The orbit, clock corrections, and differential code biases (DCB)—collectively referred to as State Space Representation (SSR) corrections—are extracted from the decoded messa...

A correlation-consistent distributed orbit determination and broadcast ephemeris generation scheme for LEO constellations

This study proposes a two-step distributed autonomous orbit determination (AOD) and broadcast ephemeris generation framework and demonstrates that the proposed method reduces the broadcast ephemeris user range error (URE) by more than 19% for GRACE-FO satellites and by 44.4% for a multi-satellite LEO constellation comp...
