PPP-RTKAmbiguity resolutionAs 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, ...
Precise point positioning (PPP) is receiving increasing interest due to its cost-effectiveness, global coverage and high accuracy. However, its application in the urban environment is still full of challenges due to the satellite tracking sky-view. Thus, we presented a comprehensive positioning model...
摘要: Precise point positioning (PPP) using the Global Positioning System (GPS) is widely recognized as an efficient approach for providing precise positioning services. However, its accuracy and reliabilit关键词: Global Navigation Satellite Systems (GNSS Precise point positioning (PPP Inertial ...
BDS, Galileo, and GLONASS are provided to support multi-GNSS and multi-frequency Precise Point Positioning (PPP) Ambiguity Resolution (AR). For RTS, the proposed orbit prediction strategy improves the 3D accuracy
This paper focuses on the precise point positioning (PPP) ambiguity resolution (AR) using the observations acquired from four systems: GPS, BDS, GLONASS, and Galileo (GCRE). A GCRE four-system uncalibrated phase delay (UPD) estimation model and multi-GNSS undifferenced PPP AR method were deve...

PPP ionospheric delaysA joint-processing model for multi-GNSS (GPS, GLONASS, BDS and GALILEO) precise point positioning (PPP) is proposed, in which raw code and phase observations are used. In the proposed model, inter-system biases (ISBs) and GLONASS code inter-frequency biases (IFBs) are...
Thanks to the international GNSS service (IGS), which has provided multi-GNSS precise products, multi-GNSS precise point positioning (PPP) time and frequency transfer has of great interest in the timing community. Currently, multi-GNSS PPP time transfer is not investigated with different precise pr...
