Resolve the Ambiguity in Real-time GPS Water Vapor Detecting with the Method of Single Epoch Ambiguity Resolution

Wei Wang

Abstract

The theory of real-time GPS water vapor detecting is briefly showed.Then the problem how to get water vapor can translate into how to get the ambiguity of wide lane,and the ambiguity of wide-lane can be got by double P code.With examples,the precision of the ambiguity of wide-lane is analyzed,and the reason why the precision of the ambiguity of wide-lane varies with the elevation is explained.
