As in the Asian-Pacific region BDS is operational next to GPS, satellite clocks (needed for Precise Point Positioning; PPP) and satellite phase hardware biases (needed for integer ambiguity resolution enabled PPP-RTK) have been estimated from a zero baseline in Perth, Australia, and applied to ...
Precise Point Positioning (PPP) is a popular technology for precise applications based on the Global Navigation Satellite System (GNSS). Multi-GNSS combined PPP has become a hot topic in recent years with the development of multiple GNSSs. Meanwhile, with the operation of the real-time service ...
Precise point positioning (PPP) is famous for its capability of high-precision positioning with just one station as long as the receiver can receive global navigation satellite system (GNSS) signals. With the rapid development of BDS and Galileo, the number of available satellites for positioning ...

Thepost-processedorbit and clock products achieve comparable accuracy with the precise products of IGS and iGMAS. The multi-frequency code and phase bias products for GPS, BDS, Galileo, and GLONASS are provided to support m...
The average root mean square (RMS) of the real-time zenith tropospheric delay retrieved from multi-GNSS PPP-AR is 12.5 mm with respect to ECMWF data while the accuracy of GPS-only results is 13.3 mm. Significant improvement is also achieved in terms of the initialization time of the multi-...
To accelerate the computation speed and reduce the time delay, a multicore parallel estimation strategy for IFCBs, code, and phase OSBs by utilizing task parallel library (TPL) is proposed, the parallel computations, including precise point positioning (PPP), IFCBs, and OSBs estim...
