Avinor has completed the installation of about 200 wide-area multilateration (WAM) antennas on mountaintops and at airports across Norway, to replace about half of the country’s conventional radars.

Defense and security company Saab provided the technology for Avinor’s WAM project. The WAM technology is designed to give a better picture of the airspace. While conventional radars look outward and upward, the WAM antennas also give a picture downward.

This is useful in search and rescue missions, for example, and increases the safety level in Norwegian aviation.
