【 摘 要 】

Precise Point Positioning (PPP) of a Global Navigation Satellite System (GNSS) can be considered as an alternative solution from the differential GNSS positioning technique. Recently, PPP technique takes the spotlight due to its low cost and large number of users. Initially dual frequency PPP technique was implemented using GPS only observations. Nowadays, it has started to combine GPS+GLONASS observations in order to improve the position accuracy and reduce the convergence time. The main objective of this research is to examine the performance ionospheric correction methods of the real time PPP using RTKLIB. RTKLIB is an open source program package for GNSS positioning. The overall results show that the ionosphere free LC method of real time RTKLIB PPP present better accuracy rather than Klobuchar model for all positioning modes.
