The article proposes a method of improving the accuracy of determining the current coordinates of a moving object moving along a loxodromic trajectory by analytical three-dimensional projection of its coordinates determined by navigation measurements in conditions of intense interference on the trajectory of its true motion. The results of testing the efficiency of the proposed method, which was carried out by numerical simulation of the algorithms described in the work of determining the coordinates of the object on the loxodromic trajectory on noisy navigation measurements. The results indicates the possibility of effective use of the proposed approach.
