Broadcast Ephemeris with Centimetric Accuracy: Test Results for GPS, Galileo, Beidou and Glonass [PDF]
Remote Sensing, 2021 Here we test the capability of the Broadcast Ephemeris Message, in both its GPS-like (Keplerian ellipse with secular and periodic perturbations) and Glonass-like (numerical integration of a 9D state vector) formats, to reproduce a corresponding precise ...

Velocity and Acceleration of NavIC Satellites using Broadcast Ephemeris [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2018 The current manuscript describes a methodology to derive velocity and acceleration of NavIC satellites from the broadcast ephemeris. A fourth-order central differencing formula is used to derive NavIC satellites’ Earth-Centred-Earth-Fixed (ECEF) velocity

Real-Time PPP Based on the Coupling Estimation of Clock Bias and Orbit Error with Broadcast Ephemeris. [PDF]
Sensors (Basel), 2015 Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations. Such an algorithm requires considerable work and hardly achieves real-time performance.
