Ground station hardware

Telemetry data are retrieved in the audio signal of the video transmitter. The signal can be directly fed into the sound card and demodulated using rtty (we have a slightly patched version in our CVS).

We also have a board with a modem for sound-card-less or > 1200bps (up to 4800bps) operations.

For flashing micro-controllers and connecting their UARTs to the laptop serial port (calibration, hitl simulation etc..), we use the following dongle.
