Refinement of trajectory parameters for GPS and GLONASS navigation satellites using IGS position data / O. N. Bogdanov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2009. ? 3. P. 53-56 [Moscow Univ. Mech. Bulletin. Vol. 64, N 3, 2009. P. 61-63].

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.

Key words: satellite navigation system, post-processing, standard mode, International Global Navigation Satellite Systems Service (IGS).
