The Air Force installed a new generation radar in 2019 on the Mount Verdun base, which houses the national command center for surveillance of French airspace. The gleaming Grandmaster 406, barely hidden by the morning veil which dissipates above the fir trees, on this small massif of the Monts d'Or, will remain firmly attached to the horizon line.
The electromagnetic pulses sent by the three transmitters via the antenna located under the radar dome, manage to detect aerial movements. The tracks of the 12,000 planes entering French airspace each day are shown.
