Study on GNSS Three Frequency Ambiguity Resolution Based on Geometry-free Model

Feixue Wang

Abstract

A new method for fast GNSS ambiguity resolution with three carriers is proposed.This method is aim at resolving the problem that the ambiguity estimation is limited to the multipath error and the length of baseline so as not to guarantee the reliability in the application of dynamic survey.The method draws the line between CIR and LAMBDA by use of success rate.It is indicated that this method which can guarantee the reliability as well as to shorten the processing time is applicable to real time dynamic survey with rapid change of environment and movement state.
