While industry averages vary within reasonable ranges, multilateration has proven to be a dramatically lower cost surveillance solution than traditional radar ... Read More

Operational Availability

When looking at traditional radar, it is easy to see that the maintenance of a multilateration system is easier and less costly.For one, a multilateration system has no moving parts. Secondly, each sensor is small and easy to reach ... Read More

Cross-Border Coverage

Multilateration systems have been planned and installed by ANSPs to provide optimum coverage within the borders of their own nations. As occurred often with SSR, surveillance coverage often extends to “spill over” into a neighboring state’s airspace ... Read More



In accordance with the “performance-based” philosophy which is currently being developed by the ICAO working groups and the complementary activities at Eurocontrol and Eurocae, the performance of multilateration systems has been regarded by national certification agencies as being equal to ICAO secondary radar standards. ...

Network Expansion

Unlike any air traffic management system before it, multilateration supports a very wide range of surveillance applications without changing its basic equipment characteristics ... Read More

Environmental Impact

More and more ANSPs face extreme restrictions on where they can place radars, due to the footprint that the machine takes up, but also because of the EM pollution that is created. Multilateration does not have this same problem ... Read More
