This projects code is available from Github https://github.com/antonjan/Raspberry_Telemetry (https://github.com/antonjan/Raspberry_Telemetry)
This code is working but has lots of place for improvements .(project started 14 Sep 2017) This project will have the files for a Cube Sat Telemetry system Using Raspberry Pi Transmitter Board.

I will be using a External GPS and temperature geometry meter to generate the Telemetry Data. The System will use GPDS and direwolf with Beacon configuration to send System data. The Diarewolf RX will be a RTL dongle withe a sharp Saw or Crystal filter as a front-end. The transmitter and receiver can be configured to be FM repeater as well. Here is a Block diagram of the BACAR Balloon telemetry system.
