About Gagarin from Space Experiment


Study of characteristics of reception of a composite nature signal from space (images, text) and extensior informing the world amateur radio association about 50 years of the first manned flight to near-earth orbit and propoganda of history of fundamental achievements of Russia (USSR) in the field of space exploration.


  • Automatic transmission and retransmission of voice information, images and text through amateur radio channel.
  • Conduct of experiments to provide beyond-the-horizon communication with small-size low-orbit SC with ionospheric layers reflection.

Flight Equipment Used:

  • Amateur packet radiocommunication complex consisting of:
    • USW Transceiver (radio station Kenwood TM D710E);
    • Antenna Feeder Device (4 pcs.);
    • Power Unit (2 pcs.);
  • Laptop RSK2;
  • Camcorder SONY HVR-Z7E;
  • Digital Camera Nikon D3X;
  • Video Communicator Kenwood VC-H1.

In the first phase of experiment MAI-75 the following is involved: the photographic and video digital equipment available onboard the ISS RS and used for photo and video recording per scenario plans and the amateur radio communication system with frequency ranges: 144-146 and 430-440 MHz for the subsequent image transfer to the ground.

Experiment Results:

Robust exchange of voice information and photo, video image produced by the ISS RS principal investigator (100-300 Kilobytes per SE session).
