Multi-GNSS observation weighting optimization for real-time precise point positioning and positioning performance analysis
The positioning accuracy of real-time precise point positioning (RTPPP) is heavily reliant on the quality of the real-time precise products employed. This study evaluated the real-time precise products provided by the Centre National d’Études Spatiales (CNES), utilizing the Signal-in-Space Range Error (SISRE) as an indicator. An elevation angle model for inter-system weighting is proposed based on the statistical SISRE results. To validate its effectiveness, RTPPP static experiment was conducted at 10 IGS stations. And RTPPP vehicle kinematic experiment was conducted using a Septentrio receiver. Experimental results demonstrate significant RTPPP positioning performance improvements utilizing the proposed elevation angle model for inter-system weighting.
