Another Round of International Space Station SSTV Activity Set for Late February


The Amateur Radio on the International Space Station (ARISS) program has announced another round of Amateur Radio slow-scan television (SSTV) activity from the International Space Station will take place later this month. Transmissions will be from RS0ISS.

The images transmitted will reprise the first series commemorating Russian space history, previously sent last December and again earlier in late January and early February. Non-stop SSTV transmissions from RS0ISS will begin on February 21 and end (at 2130 UTC) on February 23. The SSTV mode will be PD180, which can produce high-quality images with a frame scan of 187 seconds. Twelve different images depicting Soviet space pioneer Yuri Gagarin — the first human to orbit Earth — will be sent on 145.800 MHz, with a 3-minute off time between transmissions.

Received images may be uploaded to the image gallery. The ARISS team is developing plans for transmitting new images to space enthusiasts around the world in upcoming months. Additional details will be released.

During the last round of SSTV transmissions from RS0ISS, a Polish radio enthusiast, 22-year-old Radoslaw Karwacki, used an RTL-SDR “dongle” to pick up the SSTV signals from the ISS. The tiny software-defined receiver, which plugs into a computer USB port and includes an antenna port, cost about $15. He used a basic dipole and free software to receive and display the images. “I blindly tuned in on that frequency during ISS flyby and happened to receive the signal,” he told Daily Mail Science and Technology reporter Jonathan O’Callaghan.

AMSAT-UK has posted a report on the last round of SSTV transmissions in late January and early February.
