Abstract
The present invention provides an integrity analysis method based on a kinematic-to-kinematic relative positioning scenario, including the following steps: a) establishing a kinematic-to-kinematic relative positioning model, and inputting navigation data; b) calculating a float solution of an integer ambiguity; c) detecting and correcting cycle slips based on a total electron content rate; d) calculating a probability of correct fix and a probability of incorrect fix for the integer ambiguity; e) determining a fault to be detected and a satellite fault probability;calculating a standard deviation δ_(v|CF) and a position domain deviation b_m; and g) calculating an integrity risk value of a carrier phase. The present invention provides an integer ambiguity calculation algorithm for a kinematic-to-kinematic positioning system in the case of a long baseline, to calculate carrier phase integrity.
