The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710 transceiver. Those receiving the images can post them at https://ariss-sstv.blogspot.com/ for viewing by the public.
The 20 year history of ARISS will be displayed through a collection of 12 unique images sharing the amazing accomplishments of ARISS over the last two decades. SSTV signals will be sent to earth at 145.80 MHz using FM. The SSTV mode of transmission is expected to be PD 120 (PD 180 may be a second option). The event is expected to continue over a two day period.
Since it’s inception, Amateur Radio on the International Space Station (ARISS) has provided students an opportunity, through ham radio, to engage in conversation with orbiting astronauts and inspired many to seek careers in science, technology, engineering and math. Consider how you might inspire students in your area through this chance to capture images directly from space to their computers.
