# TeleGPS
-This is a GPS-based position tracker and logger.
+This is a GPS-based position tracker and logger. It uses the same GPS
+receiver and radio as 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.
-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.
+TeleGPS firmware and related ground station software is part of the
+[AltOS](../AltOS) software suite on this site. A stripped-down ground
+station program specifically for use with TeleGPS is documented below.
-For the latest TeleGPS firmware and related ground station software, please
-visit the [AltOS](../AltOS) page on this site.
+These are photos of production version 1.0, which is substantially similar
+visually to the current production version.

+## Documentation ##
+
+The manual for TeleGPS is available in [html](../AltOS/doc/telegps.html) and
+[pdf](../AltOS/doc/telegps.pdf) formats.
+
+## Software ##
+
+The TeleGPS application runs on Linux, Mac OS X and Windows. It's written
+in [Java](http://java.com) and offers the
+same functionality and interface on all three platforms. It uses the
+FTDI USB Serial drivers to communicate with the hardware. If you're
+running Mac OS X or Windows, a compatible version of those drivers is
+included with the software. You can also install a different from from
+the [FTDI Driver](http://www.ftdichip.com/FTDrivers.htm) page.
+
+TeleGPS is part of the larger [AltOS](/AltOS) suite of software, which also
+includes a dedicated [MicroPeak](/MicroPeak) application.

-## Future Plans ##
+## [History of TeleGPS](history) ##
-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.
