Multilateration (MLAT) provides accurate, low-cost surveillance using existing transponder technology. It improves situational awareness in areas where radar coverage is not available, supporting the management of complex traffic flow and safer, more efficient customer operations.

MLAT can also be used for surface surveillance at airports to provide full coverage of runways, taxiways and terminal areas.

Operational requirements for the use of MLAT are outlined in AIP Canada ENR 1.6.4. To learn more about these requirements, click here.
