Real Time Cycle Detection and Repair for Triple-Frequency ObservationsUsing Beidou Optimized MW and Geometry-Free Phase Combination
Abstract Observations made up of B1 and B2 signals in the MW combination are greatly affected by noise error and ionospheric delay error, so we propose to use the observed values of B2 and B3 signals to constitute the ultra-wide lane MW combination of weak ionosphere. The joint modified MW combination and the two geometry-free phase combination (1, 0, -1) and (0, 1,-1) of the two weak ionospheres are used for cycle slip detection and repair experiments. The experimental results show that MW pseudorange noise is reduced and detection accuracy is better, which is conducive to the detection and repair of the cycle slip.
Key words :
MW combination
