(Sorry if GIS is not the right place to post this question to).
Recently me and my school friends had a GPS software application project to pursue at the university.
A device very similar to this one was used by the application.
One day it refused to show us our current location - it was continuously showing a point in the Atlantic Ocean instead of land [we were outside of any buildings].
I did a double check by opening a default map application on an HTC Desire with Android 2.1 - it showed no current location as well.
- Does GPS signal quality depend on the chip manufacturer?
- Does GPS signal quality depend on weather?
- Is it possible to have a commercial hardware-software system which never loses the GPS signal and always shows the correct current position of a user?
