This has nothing to do with the "Literature" forum that you posted it in, so I have moved it to the "General chat" forum.
This also doesn't really have anything to do with PICs at all.
If you want to detect position, then you need a GPS receiver. There are lots of pretty cheap modules available to do that for you.
Please, go ask on a general electronics forum, these are NOT PIC support questions.
Latest test project, an LED matrix display made from one reel of addressable LEDs.
