FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering and is intended to monitor the performance of the user's navigation equipment (UNE) of the satellite radio navigation system (SRNS) of the aircraft (AC). The essence of the invention lies in the fact that the decision on the inoperability of the UNE of the SRNS is generated as a result of revealing the discrepancy between the distances between two control points, determined using the UNE of the SRNS on the one hand and the inertial navigation system (INS) on the other hand at the control times ti and ti-1 during the flight of the aircraft. This makes it possible to reduce the dependence of the generated solution on the accumulated measurement error of the INS and, as a consequence, to increase the likelihood of correct monitoring of the performance of the UNE of the SRNS.
EFFECT: invention is aimed at increasing the likelihood of correct monitoring of the performance of the UNE of the SRNS.
