The new Galileo GPS system that broadcasts across 1260-1300 MHz has resulted in the closure of a German ATV repeater.

The DARC report the Munich ATV repeater DB0QI has been closed down due to it jamming the Galileo Satnav Control Centre.

DB0QI was located 18 km from the Galileo GNSS receiver, another repeater that has been shut down is DB0ITV which was located 55 km from the receiver. It is believed both repeaters were running about 15 watts ERP.

A 2006 Galileo GPS article by Peter Blair G3LTF highlighted the problems this system could cause, see

The Amateur Satellite Service has an important allocation at 1260-1270 MHz for Earth-to-Space (Uplink) communications. The Amateur Satellite Service has already seen its allocations at 2.4 and 5 GHz rendered unusable in urban areas due to WiFi and other licence exempt devices. The Amateur Satellite Service does not have any other global spectrum allocations in the key 915 MHz to 6 GHz region.

While the German announcement may relate to a single Galileo command station being used to test the initial satellites it clearly raises concerns about what will happen in a few years time when the full Galileo constellation is deployed and 1260-1300 MHz GPS units are in widespread use.
