Airfield multilateration surveillance system “TETRA”

Airfield multilateration surveillance system “TETRA”


Airfield Multilateration Surveillance System (AMLSS) is intended for detection, surveillance and identification of aircraft during flights in terminal area, during take-off and landing, during taxing and parking,as well as for detection, identification and surveillance of transport aids and ground objects equipped with transponders and located within airfield movement area.
AMLSS “TETRA” is an element of ground-based infrastructure of airdrome air-navigational system, which maintains interaction with A-ASMGCS CAF “VEGA”. 
AMLSS “TETRA” ensures the following:
radar detection and tracking for aircraft and transport aids equipped with respective transponders and located within airfield movement area, as well as for aircraft located within air approach zone on each heading at a distance of up to 10km from runway thresholds; identification of all objects equipped with respective transponders and located within coverage zone of mutilateration system; representation of data in A-SMGCS CAF “VEGA”.
