Site Monitor

The far field site monitor is a self contained unit acting as a Mode S level 3 transponder located externally to the ground station site. Users for the site monitor are radar constructors and radar users. It provides an integrity measure on one azimuth of the radar only and is mainly used to control systematic azimuth alignment. If the secondary radar measured direction of the site monitor does not match its well known position, alerts are provided to the controller and the individual radar is removed from contribution to the radar system track.

The additional objective of the site monitor is to allow a radar operator or the ground control, the variation of all aircraft parameters sent to the parrot transponder including control word, altitude and flight identification. Further, all data link applications must be available for test purposes and verify whether the transponder has lost any data.

The site monitor shall be a dual channel system with redundant capacity in the event of a single channel failure.
