Integrated precise orbit determination for LEO constellation and BDS-3 MEO satellites using inter-satellite links and onboard BDS-3 observations

Abstract By leveraging the high-precision spatial reference established with Global Navigation Satellite System (GNSS), we propose a low-ground-dependency and low-latency Precise Orbit Determination (POD) method employing onboard GNSS, Inter-Satellite Link (ISL) observations and readily available GN...
