# TeleGPS
This is a GPS-based position tracker and logger.
TeleGPS is currently in development, with a handful of prototype
boards built. Production units will eventually be available from the
[Garbee and Garbee](https://shop.gag.com) web
store.
For the latest TeleGPS firmware and related ground station software, please
