GPS
Today i saw how GPS was in action. I used Nokia 6110 Navigator. It has in built map for bangalore. The GPS device takes sometime to get the coordinates from different satellites through line of sight. There is a Time to First Fix (TTFF) factor for each device. In the map software, I just did a search for my destination and the route was calculated. The pointer shows current position and moves according to our motion. Whenever i deviate from the suggested route the map software either warns me or recalculates the new route.
