Slip Detection

It is easier to develop the cycle slip phenomena during the carrier phase observation in GPS. In order to improve the reliability and accuracy of the system measurement, we need to diagnose and find out the position of the cycle slip, and then fix it before the data pretreatment stage which is ahead of the adjustment. Using the double-differenced carrier phase observables can eliminate the correlative error term and improve the accuracy of the measurement. Therefore, the essay studies the method of the double-differenced carrier phase cycle slip detection based on the wavelet analysis, and finally test the measured data. The experimental results showed that the detection of cycle slip is very sensitive when we select the suitable wavelet base.

Slip Detection

Cycle slip detection for single frequency Global Navigation Satellite System (GNSS) data is currently mainly based on measurement modelling or prediction, which cannot be effectively performed for kinematic applications and it is difficult to detect or repair small cycle slips such as half-cycle slips. In this paper, a new method that is based on the total differential of ambiguity and Least-Squares Adjustment (LSA) for cycle slip detection and repair is introduced and validated. This method utilises only carrier-phase observations to build an ambiguity function. LSA is then conducted for detecting and repairing cycle slips, where the coordinate and cycle slips are obtained successively. The performance of this method is assessed through processing short and long baselines in static and kinematic modes and the impact of linearization and atmospheric errors are analysed at the same time under a controlled variable method. The results indicate this method is very effective and reliable in detecting and repairing multiple cycle slips, especially small cycle slips.
