Hello,
I have tried to use a GPS in a urban environment, but it lots of problems locking to enough
satellites so it could provida point data! Is there GPS that can work with less than 3 to 4
satellites?
Here in Lisbon in most of the urban streets most of the time i only pico 2 or 3, but the GPS
needs all of the satellites for at least 10 minutes to give accurate data.
The GPS you are talking about maybe are more forgiving?
