ARISS Europe and ARISS USA teams plan to perform special SSTV Experiments using a new SSTV digital coding scheme. The first experiment in the series will utilize ARISS approved ground stations in Europe that will transmit these digital SSTV signals. These will be available for all in the ISS footprint when SSTV transmissions occur.
We kindly request that the amateur radio community refrain from the use of the voice repeater thin this ARISS-SSTV experiment on 20th of February 2022 over Europe.
The first SSTV experiment is planned for 20 February 2022 between 05:12 UTC and 11:51 UTC for five ISS passes over Europe. Please be aware that this event depends on ARISS IORS radio availabilities and ISS crew support, so last-minute changes may occur.

The used modulation is 4L-FSK or MSK w/o error correction. For the decoding of the 320 x 240 px image, the software KG-STV is required. Eric PA2EON has prepared a kgstv_ISS.zip software package for this ARISS-SSTV Experiment.
The KG-STV prepared software can be downloaded from the following link: prepared_KG-STV
The crossband repeater operates on a downlink of 437.800 MHz. Each transmission sequence will consist of 1:40 minute transmission, followed by 1:20 minute pause and will be repeated several times within an ISS pass over Europe.
The purpose of these experiments is to optimize future transmissions of SSTV images from the ISS and to investigate alternative transmission methods.

The ZIP file prepared by Eric PA2EON contains the KG-STV program, an installation and setup manual, some images and MP3 audio samples for your first tests as well as links for additional technical information about the KG-STV use.
ARISS-SSTV Upload page:
All members of the ham radio community youth and the public are invited to receive and decode these special SSTV signals. Received SSTV images can be reported to the ARISS workgroup using the ARISS-SSTV Experiment Uploadpage. The Uploadpage is closed at 21 Feb 2022 24h UTC.
For those outside of the footprint of the ISS during these tests
For those outside of the footprint of the ISS during these tests, you may wish to listen via a Web SDR.. During the last near overhead pass here Graham G3VZV checked a number of nearby Web SDRs – the only one that seemed to receive some good signals was G0XBU WEBSDR
