Abstract :
The software Atomium has been developed by the ROB to perform GPS-based time and frequency transfer in Precise Point Positioning (PPP) mode. This software has been adapted in order to produce a PPP solution for the Russian GLONASS constellation. The least square analysis of GLONASS dual-frequency carrier phase and pseudorange measurements is used to find the receiver clock solution for a specific station. This paper describes the implementation of the GLONASS constellation in the existing PPP analysis procedure and presents some preliminary results.
