Abstract

The results of GNSS differential measurements code-phase smoothing/filtering modified algorithmdevelopment and validation have been presented for the mobile objects kinematic positioning. It is shown that theupdated algorithm allows considerable increasing of the positioning accuracy and obtaining a glide coordinatesolution in comparison with the analogs.
