METHOD FOR MONITORING PERFORMANCE OF ONBOARD RECEIVER OF SATELLITE RADIONAVIGATION SYSTEM Russian patent published in 2023 - IPC G01S7/40 G01C5/00 G01C25/00 

FIELD: radio engineering.

SUBSTANCE: height of the aircraft measured by the radio altimeter used in monitoring the operability of the onboard SRNS receiver is corrected taking into account the pitch and roll of the aircraft. In this case, the pitch is corrected only if the pitch value exceeds half of the radio altimeter antenna beamwidth (ABW), roll corrected only if the roll value exceeds half of the radio altimeter ABW. This makes it possible to reduce the dependence of the formed decision about the inoperability of the SRNS onboard receiver indicator on the influence of the aircraft angular position and, as a result, to increase the probability of correct control of the SRNS onboard receiver operability as a whole.

EFFECT: increasing the probability of correct monitoring of the performance of the onboard receiver of the satellite radio navigation system (SRNS).
