The BeeLine GPS is a self contained unit with GPS receiver, ceramic patch antenna, APRS packet encoder, and 16mw 70cm radio transmitter.  For extreme altitude, a 100mw version is available to extend your range to 250,000 feet or more!

 

The BeeLine GPS also has on-board non-volatile memory that stores coordinates for download after your flight.  1 M-bit of memory means you get more than 2 hours of logging at 1 hz.  View your flight profiles in Google Earth!  Here is a flight to 17,000 feet  AGL on a single use AT K250.  Click on the picture for a larger view.

Here is a picture of the 100mw version (click for a larger version)

In addition to the BeeLine GPS transmitter, you will need a suitable receiver and APRS packet decoder (TNC).  Most 70cm amateur radio transceivers/receivers will work, as long as they have an audio output connector (most do).   The audio output connects to your PC/soundcard/smarthpone and is decoded using  APRS software, or a dedicated (hardware) decoder like the TT4 from Byonics or the OpenTracker+ from Argent Data just to mention a few.  Some handheld radios contain integrated decodes (and GPS modules, too!).  You can read more about the available radios here.

Here are some more pictures of the decoders in action, including the Kenwood TH-D7A(g).

This product will be made available to licensed amateur radio operators only, or others with the proper authorization to transmit on the desired frequency.

Limitations:

Due to the power output levels of this transmitter, proper packet reception and decoding require a FREE AND CLEAR LINE OF SIGHT between the transmitter and receiver.  

The typical usage model will be to capture and decode packets as the rocket descends under 'chute.  Once your rocket hits the ground (or goes behind that ridge), it's likely that you will lose the ability to receive and decode packets. (But you can still track the transmitter as if it were a standard RF beacon).
