An Analysis of Ambiguity Resolution Techniques for Rapid Static GPS Surveys Using Single Frequency Data

Caroline Erickson

Abstract:	Rapid Static GPS, based on specialized methods for determining carrier phase integer ambiguities, enables precise surveying in minutes. The concepts behind three prominent ambiguity resolution techniques which can be applied to single frequency data are reviewed: the Ambiguity Function Method, the Fast Ambiguity Resolution Approach, and the Least Squares Ambiguity Search Technique. Each is applied to double difference observations with some modifications. Comparisons of each of these techniques are made. Results over a 720 m and 4 km baseline are also presented. Rapid static surveys are shown to be feasible using single frequency data over short baselines with six or more satellites.
