Making a GPS unit that integrates with Google maps.
GPS technology is useful for many applications. For example, I built a hand-held GPS unit just to mess around with the EM-406. It was cool because I got some useful information like speed, heading, and altitude. I also got latitude and longitude - useful information if you know what to do with it and have some detailed maps handy. But for me, latitude and longitude readings were just numbers I couldn't readily interpret. I really wanted to find a way to display this information on a map, but I just wasn't sure how.
This project from SparkFun customer Jayesh Sukumaran is an excellent example of how to integrate GPS data into an easy to read/interpret format. Jayesh took an Arduino, the SM5100B cellular module, the EM406A GPS module, and a bunch of really clever work in Arduino, Python, and MySQL to create a GPS module that provides real-time updates to Google maps.
The cellular module used to transmit GPS data.
If you want to build your own, Jayesh did a fantastic job documenting the build and also provides all the code that was used. Great project!
