Can someone please explain how the Droid GPS works off satellites? Does it only work off 1 satellite or multiple ones like normal GPS systems? I was traveling the other day in very rainy weather and my Droid GPS worked on and off for about 2 hours. Needless to say, very frustrating. I read on another board that someone downloaded "ASTRO TASK MANAGER" and this enabled the GPS to pull from 5-6 different satellites. Any help/suggestions would be greatly appreciated. Thanks.
