Abstract | The invention discloses a range consistency RAIM method, which comprises the following steps of: 1, acquiring data of all visible satellites in a navigation system, and forming a credible satellite set by all satellite marks; 2, calculating the influence degree of each satellite on the GDOP of the whole satellite; 3, selecting satellites which have great influence on the GDOP of the whole satellite from the credible satellite set to form a reference set; 4, performing fault detection on the reference set; if a fault is detected, judging that the reference set is unreliable, otherwise, judging that the reference set is reliable; if the reference set is determined to be reliable, entering step 5; if the reference set is determined to be unreliable, eliminating the corresponding minimum satellite in the reference set from the credible satellite set, and returning to the step 3 to reselect the reference set; and 5, forming a test set by all the visible satellites except the reference set, and performing fault det |
