Default How to get GPS location faster

Please Login to Remove!

I am using 9530 and my provider is T-Mobile. It takes me about 8 sec or more for getting location. This is part of the code:
//accuricy is 100
LocationProvider locationProvider = LocationProvider.getInstance( criteria );
Location location = locationProvider.getLocation( -1 );
qualifiedCoordinates = location.getQualifiedCoordinates();

Is it possible to make this process faster? Let say 1 sec.

Carry a map? Lol


I don't think you can do 1 second. Tmobile will allow you to use aGPS to assist pinpointing. Agps is basically using the cell towers to trianglate you as the gps works.

8 seconds is actually very fast for autonomous GPS first fix - I would actually think that is impossible. A first fix for a cold chip is probably more like 20 seconds MINIMUM.

Now, once the chip is warm, and it has found a few satellites and received position info from them, you can pretty much get continuous fixes. Navigation systems do this, for example.

The method to do this is to set up a LocationListener and set the frequency to something like 3 seconds.

One warning: this will burn your battery up very quickly. On my Storm, I can get maybe 3 hours of battery while running the GPS continuoulsy.
