I have downloaded the Mobile Locate app on BlackBerry Torch 9810 with AT&T. I live in a brick building with concrete floors. My windows face north. When I am at home the app has so much difficulty determining my latitude that it usually estimates my location as being a block or two north of me and sometimes three blocks north. I think what must be happening is only the satellites from the north can get my signal and those from the south are shielded from it. Thus, the location is biased north. Is this common. I notice that my GPS sometimes estimates an error as high as 300 meters. When I am outside sometimes over a half dozen satellites get my signal and the estimated error is as low as 10 meters and the locations seem more accurate. What exactly is going on?
