I'm sure someone else will ask the basic questions, too, but here's the list
I always ask students who want a state-of-the-art GPS:
1. What do you intend to use it for? Routine walking around, semi-precise
data recording, or cadastral equivalent surveying? The receivers, antennas,
and integrated software are all different, and price goes up as you move up
the line here.
2. Do you want to be able to see results as a standalone unit (handheld) or
as a data recorder/logger that will feed raw data to another
computer/software system (like ArcPad, Mapinfo, etc. etc.).
3. How much accuracy do you need? Decimeter, meter, 10 meters, general
neighborhood, etc.
4. What kinds of conditions will you be working in? Some units do better
than others at correcting for or ignoring false signals you might get in
urban canyons, under tree cover, or on densely overcast days.
5. What other features do you need, want, and dream of?
Once you write down the answers to all those, you can begin some serious
shopping!

Hello List,

compromise on the buy either.

I need a GPS + Mobile Phone
Kindly give ur suggestions and links ...
Thanks a bunch
Best Regards,
Gaurav.
