Graves Satellite Radar, Broye-Les-Pesmes, France

This satellite radar is Europes' answer to the American Navsparsur radar fence. It is a "bi-static" system (using separate tx and rx sites) operating on 143.050 MHz. I won't put any detail here, but the current level of knowledge about this facility is detailed in the following document, which has been compiled from various sources: A Graves Sourcebook, by Allen Thomson (PDF)
