Cycle-slip Detection, Determination, and Validation for Triple-Frequency GPS

Zhen Dai, Stefan Knedlik and Otmar Loffeld

Abstract:	A real-time algorithm to detect, determine and validate the cycle-slips for triple-frequency GPS is proposed. By evaluating different geometry-free phase combinations, two optimal geometry-free combinations are selected for cycle-slip detection. In order to determine the size of the cycle-slips, the cycle-slip search space will be decorrelated using LAMBDA technique. The actual cycle-slip candidate will then be identified according to the least-squares principle. An efficient validation approach is also suggested. Simulations indicate the reliability of the entire algorithm.
