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 of the combined method compared with stand-alone GPS solution using CSRS-PPP online service processing for both static and kinematic modes. The overall results show that the GPS+GLONASS constellations does not improve the convergence time of kinematic PPP, while the static mode results of the GPS+GLONASS solution present better accuracy rather than the stand-alone GPS solution.
