Abstract
The carrier phase ambiguity resolution is important for fast and high precision relative GPS positioning. In this paper, three ambiguity resolution techniques: Fast Ambiguity Resolution Approach (FARA), Least Squares Ambiguity Search Technique (LSAST) and Least squares AMBiguity Decorrelation Adjustment (LAMBDA), which can be applied to the single frequency data are reviewed from statistical view points. We compare the techniques by applying each to the single frequency double difference observations with some modifications. Also comparisons using the real receiver data are made.
