Abstract:The algorithm of real-time GLONASS satellite clock corrections is investigated and the real-time satellite clock corrections are used for RT-PPP. Based on software developed by ourselves, undifferenced ionosphere-free phase and range observations collected from global GNSS stations are used to estimate real-time GLONASS clock corrections. The results show that the real-time GLONASS clock corrections are comparable with the ESA final precise clock corrections. The RMS of real-time clock is better than 0.5 ns with respect to the ESA final satellite clock. The accuracy of GLONASS RT-PPP is a centimeter in static mode, and better than 30 cm in simulated kinematic mode, when real-time satellite clock corrections are used.
