Restricted areas at airports are often hard to monitor. Even though other non-cooperative surveillance technologies such as surface movement radars may be able to detect non-cooperative vehicles or aircraft entering a restricted area, they may not be able to detect individual human bodies.
For both safety and security purposes ASW sensors can be set up temporarily, or permanently, to protect an area within the airport. Sometimes, ongoing construction may cause a section of the taxiway or runway to be closed. In these situations the technology can be placed to ensure monitoring of these restricted areas or taxiways.
This information can be sent either to ATC or the airport security department. In this configuration, ASW Technology uses highly moveable GroundPlug anchoring that facilitates rapid positional changes with regard to temporary works on a runway or taxiway.
