"Through the appointment" December 1-2 International Space Station 145.80MHz SSTV Image Transmission

Moscow Aerials SSTV event, December 1 (Wednesday) and December 2 (Thursday) International Space Station 145.80MHz SSTV Image Transmission

December 1, 2021 (Wednesday) will start using an amateur radio band from the ISS (International Space Station) to the Moscow area to send SSTV (slow scanning TV) images.

December 2 (Thursday) 20:00 to December 3 (Friday) 2:05

(Date and time may be changed according to the safety work schedule).

During this period, the International Space Station has two or three times through my country, but only some of the northern parts of my country may receive a good full SSTV signal. In other regions, the downlink signal may also be received based on the receiving facilities and location.

The experiment will be carried out as part of the "Moscow Aviation Academy" SSTV activity, commonly known as "MVI", the SSTV transmission frequency from the international space station is 145.80MHz (due to Doppler frequency shift to 5kHz), "RS0iss" "in FM mode Make a call number (there are some deviations).

Refer to the satellite through the satellite in Japan to view the path of 21 points from the relevant link below the article "Jamsat (Japanese Amateur Satellite Communications Association)", so it is a good reference to it.

During the period of operation, the international space station arrived at Jiuzhou, Okinawa and other places.

(Time from JST and Jamsat announced)

Note: Japan time is more than an hour than my country Beijing time

Although this depends on the position and antenna, "30 degrees or greater elevation" is a guidelines for receiving SSTV images.

"Moscow Aviation Institute / National Research" is a Russian higher education institution, providing technical education and training in aviation, aerospace, rockets, and is established in 1930 in the period of the former Soviet Socialist Republic.

This time, as part of the SSTV activity carried out by the organization, an experiment will be performed using a 145.80MHz amateur radio frequency band from the International Space Station (ISS) to transmit the SSTV image mainly for the Moscow region.

The frequency used is 145.80 MHz (due to Doppler frequency shift, the deviation is approximately 5 kHz), and the SSTV signal (PD120) is placed in the FM mode and transmitted. The rails of the International Space Station are published on the Internet, as well as the convenient smartphone apps such as "International Space Station Detectors".

The SSTV signal transmitted from the International Space Station is sent from the JVC Kenwood Recent V / UHF band transceiver "TM-D710E" installed in the Russian International Space Station Service module.

Amateur radio "TM-D710E" is installed in the Russian International Space Station Service Module

How do you receive it, please see the related links below, "Let’s receive SSTV in the ISS / International Space Station with SDR # + RX-SSTV. (Plus RTL-SDR)". You can also view the latest schedule in the Related Link "ARISS-SSTV Image".

In addition, images received on the ground can be published online (image upload) and viewed in the "ARISS SSTV Gallery". Many stations have successfully received the SSTV image transmitted from the International Space Station in the past, and the received image has been uploaded to social media.
