ISS HAMTV simulation with Raspberry PI

We have reached our first step in the preparation for the reception of HAMTV of the ISS: we can now demodulate and decode the video using the real ISS transport stream! We have setup two “MiniTiouner” kits (thanks to Gilbert F1FWX!) and set up an experimental DATV transmitter using a Raspberry PI3 and the excellent RPIDatv from Evariste F5OEO.
Please find below our system simulating transmission of the ISS transport stream that was transmitted during the 05/05/2016 Tim Peake ARISS contact and reception with our MiniTiouner kit:

Please find below a schematic of the setup that we will use to simulate, as well as possible, the ISS HAMTV using a Raspberry PI and RPIDatv , and also our setup for the ISS HAMTV reception:

The next step will be to use a dish and LNB for a real ISS pass.

One of our objectives is to be ready to act act as a “relay” HAMTV during the next ARISS contacts with Thomas Pesquet in order to retransmit the received video to the schools that taking part.
