title = "Orbit determination using combined GPS + Beidou observations for low earth cubesats: Software validation in ground testbed",
abstract = "Nowadays, satellites in low earth orbit (LEO) can benefit from Global Navigation Satellite System (GNSS), such as Global Positioning System (GPS) of United States, to estimate positions and velocities. As China{\textquoteright}s BeiDou Navigation Satellite System (BDS) has been formally operational since the end of 2012, standalone Beidou and combined GPS + Beidou positioning techniques tend to be applied in the future space missions. However, no LEO satellites have been operated with Beidou receivers at present. Hence Beidou-based precise orbit determination (POD) technique is required to be tested and verified on ground at first stage. This study is to test the GPS + Beidou orbit determination software in ground testbed. GNSS data collected from iGMAS (International GNSS Monitoring and Assessment Service) and MGEX (Multi-GNSS Experiment) stations are processed in both static and kinematic PPP (Precise Point Positioning) modes. Decimetre level of positioning accuracy is achieved. The inter-system biases between GPS and Beidou are estimated and analysed. Results indicate that GPS + Beidou solutions are more precise than the standalone GPS solutions.",
