Title:
SYSTEM AND METHOD FOR MONITORING ERRONEOUS ALARM FROM IONOSPHERE GRADIENT MONITOR
Document Type and Number:
Japanese Patent JP2015145868
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a monitor system and method for reducing erroneous alarms of an ionosphere gradient monitor.SOLUTION: A method for reducing erroneous gradient alarms of the ground station of a satellite navigation Ground Based Augmentation System (GBAS) comprising a plurality of satellite navigation system reference receivers has a step 610 for generating, in the GBAS ground station, an alarm signal having an ionosphere gradient monitor (IGM), a step 620 for determining whether or not the alarm signal is an erroneous alarm on the basis of the data obtained for the carrier phase measurement received from the plurality of satellite navigation system reference receivers, and a step 630 for cutting off the alarm signal pertaining to at least a first duration time on the basis of the determination.
