Adaptive median filter for geographic coordinates of the satellite navigation system receiver

Receiver of the underwater vehicle satellite navigation system is a source of geographic coordinates; accuracy in their determination affects the accuracy of the system. Errors in the receiver data of the satellite navigation system appear in the form of noise and aperiodic significant deviations from the real value of short duration, i.e. splashes. The paper presents a developed adaptive median filter algorithm that allows filtering out noise and splashes in the geographic coordinates of the satellite navigation system receiver. The proposed filter is operational in all modes of the underwater vehicle motion, introduces no delays, and does not require the use of data from the additional measurement devices. The filter parameters are set based on dynamic characteristics of the underwater vehicle, and are not associated with characteristics of a specific receiver of the satellite navigation system.
