SYSTEMS AND METHODS TO MONITOR FALSE ALARMS FROM IONOSPHERE GRADIENT MONITORS

摘要

FIELD: measurement; testing.;SUBSTANCE: invention relates to communication engineering and is designed to monitor false alarms from ionosphere gradient monitors. To this end, the method for minimising false alarm on unacceptable variations includes the following steps: generating an alarm signal with an ionosphere gradient monitor (IGM) at a GBAS ground station; determining whether the alarm signal is a false alarm based on data derived from carrier phase measurements received from a plurality of satellite navigation system reference receivers; blocking the alarm signal for at least a first duration of time based on the determining.;EFFECT: technical result consists in high noise immunity of receiving signals.;20 cl, 6 dwg
