Improving GLONASS Precise Orbit Determination through Data Connection

open access: yesSensors, 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 ...

Combined GPS/GLONASS data processing [PDF]

open access: yesGeo-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 ...
