| Abstract: | The model for optimum selection of the test quantities of triple-frequency cycle slip combinations is investigated according to the theory of multi-frequency cycle slip detection.Furthermore,taking the smallest variance of cycle slip as the standard,and the wavelength of phase combination as the constrain condition a linear independent carrier phase combinations are selected as cycle slip test quantities.By use of the triple-frequency GPS observation data from IGS,the performance of the cycle slip detection combinations is tested.The results show that the combinations proposed could effectively detect cycle slips on every frequency.Consequently,it can play a significant role in the practical triple-frequency GPS data pre-processing. |
