My old point-and-shoot camera with a built-in GPS receiver can go from completely powered off (battery out) to an accurate GPS fix in under 4 minutes as long as it has an unobstructed view of the sky. So your time estimate is way too high in most cases. Cell phones are even faster because they pick up an initial approximate location from the cell phone tower and also automatically download GPS satellite ephemeris data. |
