# 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.
+This is a GPS-based position tracker and logger. It uses the same GPS
+receiver and similar radio to our flight computers, but does not include
+pyro circuits. This allows the board to be small and light, so that it will
+fit well anywhere you need a good GPS tracker.

+These are photos of an earlier prototype version, the final boards are
+slightly wider:

* Offers custom digital telemetry, APRS and direction beacons
* High-dynamics GPS receiver for accurate tracking
* Uses 3.7V Lithium Polymer battery.
-* 1.5 x 0.8 inch board designed to fit inside 24mm airframe coupler tube
+* 1.5 x 1.0 inch board designed to fit inside 29mm airframe coupler tube
* 2MB on-board data logging flash
* Built-in USB connection for configuration, data download and battery charging
## Future Plans ##
-The GPS performance of the initial prototypes was disappointing. We're
-evaluating different GPS antennas and board geometries to resolve that, and
-expect at least one more prototype version will be required once we choose
-the optimal combination.
+We expect to have these for sale in late May 2014.
