The great folks in #highaltitude on freenode have developed the habhub tracker, which is an amazing piece of software for tracking weather balloons all over the world.
It doesn't quite fit my needs as I am often in a chase car many miles from the nearest available wireless service, and still need to track a balloon. Enter baltrak, a bit of go and javascript that I wrote in a frenzy to enable just that.
This software can run 100% offline with zero dependencies, does basic map tile caching, and can use pregenerated map tiles. It contains a go service that listen to a serial port for strucutred data, and spews it over a websocket to a browser pointed at localhost.
Don't rely on this to work. For any reason.
