Abstract

Efficiency of the use of ambiguity resolution procedure for Precise Point Positioning (PPP) technique in Global Navigation Satellite Systems (GNSS) is analyzed in the article. Two different observation models with decoupled clocks are described and comparative results are shown for them in terms of positioning accuracy and duration of convergence time. The use of atmospheric constraints for PPP is presented here with conclusions about their efficiency in case of full instantaneous reset of filtering process.
