GPS Satellite Question

[Skean Dhude]

Like everything else it has its place. If it is on it gives you a starting point plus a set of maps you can walk with.

The system only needs power and the ability to receive the signals from the Sats, it then does some complicated maths with the more Sats it sees the more accurate it is. Sounds like you had a faulty one there S13 or it could only see one sat.

When you switch them on it tells you the number of sats it can see. It needs a min of three to place you close to where you are. The more the better though.

My view is if it is there, even adjusted to a 50 M window, I'd use it for a starting point. If it isn't there then I have maps and things for fallback.
