Precise orbit determination for GPS and GLONASS satellites on the basis of IGS data

Proceedings of 5th International Conference on Recent Advances in Space Technologies - RAST2011, 2011
This paper considers the problem of precise orbit determination for GPS and GLONASS navigation satellites. Satellites' position aiding information provided by the International GNSS Service (IGS) and becomes available on specialized web sites is used. The paper contains the description of algorithms that estimate the position and the relative velocity ...

Refinement of trajectory parameters for GPS and GLONASS navigation satellites using IGS position data

Moscow University Mechanics Bulletin, 2009
The inaccurate knowledge of navigation satellite trajectory parameters is one of the factors decreasing the accuracy of processed measuring data. The problem of refining such parameters in a post-processing mode on the basis of IGS position data is considered.
