Advanced Surface Movement Guidance and Control System

From Wikipedia, the free encyclopedia

The Advanced - Surface Movement Guidance and Control System is a system at airports that uses surveillance sources such as Primary surveillance radar, Secondary surveillance radar and Surface Movement Radar to provide an accurate picture of the activity on the airport surface in order to prevent accidents. SMGCS (pronounced "Smigs") provides routing, guidance and surveillance to aircraft and ground vehicles to ensure smooth traffic flow under all weather conditions within the aerodrome visibility operational level (AVOL), traffic density and aerodrome layout to maintain safety.
