摘要：
A real-time algorithm to detect and determine the cycle-slips for multi-frequency GNSS Is proposed. The cycle-slip detection is achieved by constructing two geometry-free combinations of carrier phases. Several criteria are established to assess the performance of these combinations In order to achieve better detection sensitivity. Considering the similarity in the Integer nature of cycle-slip and phase ambiguity, we apply the ILAMBDA technique to quantify the sin of each slip. Some tots based on a GPS simulator have been carried out and the results are given to show the performance of the entire algorithm.
