The authors conduct a research of the error dynamics of the algorithm of the secondary processing of navigation signals of the global navigation satellite system based on extended Kalman filter. The article shows that at the stages of intense maneuvering the accuracy of a certain positioning of a highly dynamic consumer increases to 1.5 times. Presumably the reason for this is the mismatch of the dynamic model of the object, embedded in the optimal linear filter and real dynamics of users' movements.
