Aerodrome 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 aerodrome movement area.
TETRA AMLSS is the element of ground-based infrastructure of airdrome air-navigational system, which maintains interaction with VEGA A-ASMGCS CAF. TETRA AMLSS ensures the following:  radar detection and tracking for aircraft and transport aids equipped with respective transponders and located within airdrome movement area, as well as  for aircraft located within air approach zone on the 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 of VEGA A-SMGCS CAF.
