What kind of information is displayed by the ground surveillance radar scope on Advanced Surface Movement Guidance and Control Systems (A-SMGCS) or similar systems like ASDE-X?
Advanced Surface Movement Guidance and Control System (A-SMGCS) provides controllers (eventually pilots and vehicle drivers) with situational awareness on the movement area and normally consists of three type of sensors. Surface movement radar, MLAT and ADS-B.
The kind of information is displayed to the controller is dependent on what are the sensors used and the capability of aircraft and vehicles on the ground.
- If the A-SMGCS is equipped with Surface Movement Radar (SMR) it can display the moving vehicles and aircraft on the maneuvering area. (except in areas where tracking is inhibited ) to the controller. But manual correlation is required to identify the target.
- If ASMGCS is ADS-B capable, controllers display will show Aircraft or vehicle Identification (ACID), Essential Flight Plan details like destination etc and type of aircraft also in addition to the exact location of the aircrat or vehicle. For this to work, Aircraft/vehicle should be ADS-B capable.
- using MLAT (Multilateration ) ASMGCS system displays postion and ACID and other FPL details to the controller if the aircraft SSR transponder is in operating mode. System correlate the transponder code with the flightplan.
Depending upon the level of ASMGCS operation , it can also display the taxiway route, SID, Runway assigned etc to the controller.
If the target is obtained from ADS-B or MLAT then it is called a cooperative sensor target. It will be displayed in a different symbol.
