Australia still has the usual GPS satellite coverage, despite the war.
Years ago Canberra Ornithologists Group purchases a couple of Magellan GPS 300/Pioneer receivers for atlassing. While they were fine for that purpose for a while, we have found that, after prolonged storage, they would not work properly. We sent them to Magellan in Perth for service and were advised, by the Magellan Service Manager, that they had become unserviceable. He said that such receivers need to be used reasonably frequently or they die. As a result, we have upgraded to parallel channel receivers and make sure we give them a chance to update their almanacs at least every two weeks.

I had not used two Magellan GPS units for a few months until last week. I have had great difficulty getting them to give readings here at Nundah in Brisbane. They will usually find one or two satellites but not lock in to a position. Both have new batteries and have been recalibrated. There are no obvious obstacles in the way - trees, buildings etc. A friend at St Lucia is also having problems.
