Abstract

The satellite network of Chinese Beidou system and the European Galileo System are on-contraction recently, which promotes the development of Multi-GNSS high-precision fusion applications. In this paper, the algorithm of multi-GNSS real-time clock fusion estimation is studied deeply, the real-time augmentation message processing strategy is also discussed and real-time orbit data processing and analysis are carried out based on PANDA software. Then the multi-GNSS real-time augmentation system prototype is constructed based on the GNSS real-time stream which could be obtained currently and real-time augmentation messages including GPS, BeiDou and Galileo are broadcasting on the Internet. The experiment results show that the real-time augmentation message signal-in-space ranging error(RTAM-SISRE), effecting the user’s actual positioning performance, of GPS is about 4–7 cm, that of Beidou IGSO/MEO and Galileo is about 10 cm and BeiDou GEO satellites’ is about 33 cm, respectively. The real-time Precise Point Positioning (PPP) results prove that 5–7 cm horizontal RMS and better-than 10 cm vertical RMS based on carrier-phase observation can be obtained.
