FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering and can be used in the creation and modernization of means for monitoring the integrity of the navigation field of global navigation satellite systems (GNSS) in terms of monitoring the reliability of information received by the navigation equipment of the consumer (NEC) of the aircraft. The purpose of the invention is to ensure the possibility of monitoring the reliability of the information received by the aircraft in the temporary absence of received additional information parcels (AIPs) from the local control and correction station (LCCS). In the claimed method, in the absence of an accepted AIP in an acceptable time interval relative to the next control point in time, the decision on the reliability of the information received by the aircraft NEC is formed as a result of identifying a discrepancy or correspondence between the basic and predicted estimates of the distances between the aircraft and the LCCS. At the same time, the predicted estimate of the distance between the aircraft and the LCCS is formed using the two previous control estimates of the distances between the aircraft and the LCCS from the condition of rectilinear motion of the aircraft at the predicted time interval.
EFFECT: method makes it possible to monitor the reliability of information received by the aircraft NEC in the temporary absence of received AIPs from the LCCS.
