threadjackistan: I'm not sure how gps works, range or angle, but if its range(checking the distances in time signal to determine relative distance) and you knew you were on the ground and roughly where you were, the because the potential location of yourself would roughly be a circle from two of the satelites, couldn't you narrow down your location to just two fairly separate points? Again, assuming you were on the ground and had a good DEM.
Ivo Shandor: GPS devices have an almanac telling them approximately where the satellites are going to be in the sky at any given time. You can see that map regardless of whether or not you're receiving a signal from any of the satellites.
Born_Again_Bavarian: . I put my phone in Airplane mode, turned on the GPS and fired up my GPS tester. I can see 21 satellites.I can't connect to any, of course
Born_Again_Bavarian: StopLurkListen: GPS needs a line-of-sight to the satellite, so unless they drop your luggage off in a field ... good luckNot necessarily. I sit on the 1st floor of a 3 story building. There are at least 3 walls between me and outside. I put my phone in Airplane mode, turned on the GPS and fired up my GPS tester. I can see 21 satellites.I can't connect to any, of course but then I don't have any kind of antenna nor is my phone a GPS device first.
