I'm becoming quite interested in Global Positioning Systems and was wondering if anyone could tell me a little about the software involved. I'm guessing that in order to make some GPS software you'd have to build a GPS receiver from scratch and program the chip set yourself. Does anyone know of any open source projects along these lines that aren't too advnaced?
Sounds like a BIG project. Some of the GPS manufacturers provide doc for the interface to their hardware. Garmin and Magellan and maybe Furino(?). I've written software using these interfaces to run over a serial port connection to upload and download waypoints, routes and tracklogs between the GPS and my PC. I've used it for several seasons when cruising.
