The influence of geometric factors and data processing algorithms on the error of GNSS position in the GFO 'MIHNEVO'

摘要

The results of the analysis of the navigation task solution in the conditions of registration of the signals of the globalnavigation satellite systems GPS and GLONASS in the Mikhnevo GFO (the geophysical observatory) are presented. It isshown that in the classical algorithm, the choice of satellites from the observed constellation should be made notaccording to the criterion of elevation, but by the number of conditionality of the navigation task matrix. The use ofadaptive iterative algorithms almost completely compensates geophysical perturbations while maintaining the twofrequencyregime.
