| Abstract: | With the test of cycle slips which come from the Tri-band combination of the GPS observation,we propose a method that can select the optimal combination of observation model using the Least-squares principle.With this method we choose an optimal combination model that is（0 1-1）（-3 1 3）（-7 9 0）.Through the relationship between the carrier frequencies,we simulate the L5 carrier data.Preparation of a cycle slip detection software.And with the instance checking,we find out this combination model has more accurate than other models on cycle slip detection. |
