Another interesting tidbit. I've added it to my webpage. > It is hard to imagine that the suction cup could fail and you not notice > it with the gps mounted where it is. ... Well, I don't live in the hallway and so far it has always been noticed within a few hours. I suppose it would be possible to write a script to sound an alarm whenever a significant variation in the signal from the GPS is detected, but such measures would be of little benefit in the event of my absence. I think a redundant receiver is a much better way to tackle this problem and the dangling GPS device will be noticed soon enough anyway. > ... I'm afraid my family would shoot me. What charming family values. Sounds like a nest of hot-headed, anal retentive technical types. :-)) > I run the cable out a basement window and the gps is mounted on the > front iron rails of the house using its magnetic mount.

A view of the ecliptic, which includes the stationary SBAS satellites, is always better than a polar view. Before it was mounted in the skylight, my GPS device had something like a 120 degree view of the northern sky (from the Netherlands), but despite the fact that it requires a lock on only one satellite at all times, it would still lose synchronization regularly. On the other hand, a friend of mine, who lives nearby, still makes do with a similar view of the southern sky and never loses synchronization.
