New Strategy for On the Fly Ambiguity Resolution

Hasanuddin Z. Abidin

Abstract:	Resolving the carrier phase cycle ambiguity ‘on the fly’ is the key to precise (centimetre-level accuracy) real-time differential GPS kinematic positioning. As it requires ‘on the fly’ isolation of the correct ambiguity from the geometric range and the errors and biases in the observation, it is not an easy task to accomplish. A few techniques have been proposed to perform this difficult task such as extrawidelaning, ambiguity mapping function, and the least-squares approach. A new strategy based on the synergism of these techniques is introduced in this paper. The mathematical methodologies involved are given, and the performance of the new strategy with respect to the use of rejection criteria and satellite geometry is highlighted.
