Combined GPS/GLONASS data processing [PDF]
Geo-spatial Information Science, 2002 To obtain the GLONASS satellite position at an epoch other than reference time, the satellite's equation of motion has to be integrated with broadcasting ephemerides. The iterative detecting and repairing method of cycle slips based on triple difference residuals for combined GPS/GLONASS positioning and the iterative ambiguity resolution approach ...

Sensitivity of GPS and GLONASS orbits with respect to resonant geopotential parameters [PDF]
, 2018 The Center for Orbit Determination in Europe (CODE) has been involved in the processing of combined GPS/GLONASS data during the International GLONASS Experiment (IGEX). The resulting precise orbits were analyzed using the program SORBDT.

Improving GLONASS Precise Orbit Determination through Data Connection
Sensors, 2015 In order to improve the precision of GLONASS orbits, this paper presents a method to connect the data segments of a single station-satellite pair to increase the observation continuity and, consequently, the strength of the precise orbit determination ...
