getting incorrect GPS points

[craigr]

I am writing a GPS oriented android application and am getting a
strange bug. When driving around town, it is capturing my GPS
position just fine, but when the phone is sitting on my desk in my
basement (where the GPS signal is intermittent), the application seems
to log random locations that can be up to a mile away from my actual
location.

Any ideas what might be going on? Is there anything that I can put
in my code that will help filter out these incorrect GPS positions?

Thanks,

Craig

Have you tried receiving CPS status messages to distinguish between "synthetic" GPS (derived from cell tower location and skyhook location estimates)?

On the phone, I have “Use wireless networks” disabled in the settings.  I had thought that this would ignore any cell tower locations.   Also, in the code here is how I am requesting the GPS service

 

private void registerInitialListeners() {

            getLocationManager().requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, meters, this);

      }

GPS Status and GPS Test are both good Android apps to test the GPS.
Maybe their diagnostics might showcase the problem.
