Multi Frequency Monitor for Detecting Ionospheric and Tropospheric Disturbances

摘要

System and method for a Ground Based Augmentation System (GBAS) for detecting ionospheric and tropospheric disturbances using Multi Frequency Monitor. Receiving signals from a plurality of receiver pairs and determining a monitor measurement of tropospheric delay variation using data from at least one pair of the plurality of receivers. Determining a monitor measurement of the sum of tropospheric and the sum of ionospheric delay variations using data from the at least one pair of the plurality of receivers. Combining monitor measurements of tropospheric delay variations and of ionospheric delay variations into an ionospheric delay estimate.
