MAI-75 ARISS-SSTV in December

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

MAI-75 April 14 and 15

Details are a bit sketchy at this point but it appears that the Moscow Aviation Institute will be conduction SSTV image transmissions from ISS on April 14 from around 15:00 to 18:00 UTC and again on April 15 from around 14:00 to 19:00. It appears they will be using the large image quality transmission mode of PD290 during this period. Folks will have to be extremely lucky to capture a full image during a pass of the ISS since the transmission time for each image will be nearly 5 minutes and there should be a gap between image transmissions to reduce the duty cycle on the radio. Transmissions are planned to occur on 145.800 MHz.
