Slow Scan Television (SSTV) images transmitted from the International Space Station and other ARISS supported satellites

Images will be downlinked by ISS on 145.800 MHz.

International Space Station

Looks like the MAI-75 folks have scheduled some SSTV activity during specific periods each day from Dec 6-8. The times correlate to a small number of passes each day in range of Moscow.

Dec 6, 2017

Setup and power on – 13:40-14:20 UTC

Power off – 17:05-17:15 UTC

Dec 7, 2017

Power on – 13:45-13:55 UTC

Power off – 17:30-17:40 UTC

Receive sstv image from International Space Station

In commemoration of the 20th Anniversary of ARISS. The Amateur Radio on the International Space Station (ARISS) program is planning a slow-scan television (SSTV) event starting on Thursday, July 20, and continuing for 2 days.

SSTV transmissions are set to get under way at 21:25 UTC, wwill feature 12 images from past and present ARISS activities. The SSTV signal should be available nearly anywhere on the globe at some point during the event. The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the onboard Kenwood TM-D710 transceiver. Those receiving the images can post them at https://ariss-sstv.blogspot.com/ for viewing by the public. SSTV signals will be transmitted on 145.80 MHz using FM. The SSTV mode is expected to be PD120, with PD180 as a possible second option. Free SSTV decoder software is available on the Internet.

For more information and you can read the blog post from the ARISS site at: http://ariss-sstv.blogspot.com

ARISS Celebrates it’s 20th Anniversary through SSTV Event

In commemoration of our 20th anniversary, the ARISS team is planning to transmit a set of 12 SSTV images that capture the accomplishments of ARISS over that time. While still to be scheduled, we anticipate the SSTV
operation to occur around the weekend of July 15. We are planning for at least a 2 day operation, but are working for a potential longer operation. Note that all of this tentative and may change based on crew scheduling and
ISS operations.

Starting with our first meeting in November 1996, our joint operations on Mir, becoming the first operational payload on ISS in November 2000 to our 1103rd school contact (so far), ARISS' accomplishments have been tremendous. We have touched the lives of many and inspired and educated countless students to pursue science, technology, engineering and math careers.

Please stay tuned as more details on our SSTV event will be communicated in the coming weeks. Please spread the word. And think about how you can get students in your area involved in capturing these images. We would love to hear your stories on how that goes.
