I haven't found many details about this place. It is referenced in an article that names it in reference to some tests of the French Syracuse Military Communications Satellite.
Note that there are two perimeters and most parking is outside the outer fence.
Two large dishes and a smaller dish are both inside the inner perimeter.
Interesting L-shaped arrays in the NW and SE corners.
Any ideas?
This facility is part of the "Centre de Transmissions France Sud" (or CTM France Sud), operated by the Marine Nationale, near Bram.
I think there is another site in low-rez area, near Villemagne (43.36, 2.11).
Here is a 2:20 video, showing clearly the antennas.
This is were the satellite Syracuse 3A is operated.
In the western part of the site are two ELTA S-Band TTCET stations.
