3) How does QuickGPS work ? it retrieves what kind of information from Internet ? How it can know where I am if I'm at a location where there are no satellite signals ?
Thanks.

1) Depending on the application -- It can be both.
2) It is not always on. Thanks to the .NET platform.
3) All GPS applications do is grab your coordinants according to the relative positions between multiple satellites. If you can't get a signal, well, you don't get a signal.
