Phase Reduce False Distance Law and Ionosphere Residual Error Method Detect and Correct the Cycle Slip

摘要

During GNSS precision positioning data processing, the detection and correction of the cycle slip has been a core problem all along. Aiming at the disadvantages that there are some multi-value problems in the cycle-slip detection of the ionosphere residual error method and the phase reduce false distance low is not sensitive to the small cycle slip, this paper puts forward combining both methods to deal with the cycle slip. The case analysis indicates that the principle of this combination method is simple; the calculation speed is fast; it has strong practicability.
