ARISS SSTV Event April 11-13

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) April 11-13 on 145.800 MHz FM to celebrate Cosmonautics Day and Women in Space

The event is slated to begin on April 11 at 16:30 UTC for setup and operation and continue until April 13 ending at 12:00 UTC. These times are tentative and are subject to change due to crew availability.

Images will be downlinked at 145.8 MHz +/- 3 KHz for Doppler shift and the expected SSTV mode of operation is PD-120.

The theme for this event will be celebrating Cosmonautics Day and Women in Space.

Radio enthusiasts participating in the event can post and view images on the ARISS SSTV Gallery at https://www.spaceflightsoftware.com/ARISS_SSTV/

The signal should be receivable even on a handheld with a 1/4 wave whip. If your rig has selectable FM filters try the wider filter for 25 kHz channel spacing.

Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV (SSTV) images on 145.800 MHz FM probably using the SSTV mode PD-120.

The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda) using a Kenwood TM-D710E transceiver.

• April 7 start about 08:00 GMT, stop about 15:35 GMT*
• April 8 start about 08:40 GMT, stop about 16:10 GMT*

CAS-10 CubeSat has an Amateur Radio Transponder

CAMSAT’s CAS-10 is an 8U CubeSat that will carry an Amateur Radio VHF to UHF linear transponder for SSB communications.

A follow on mission from CAS-9 and also known as Hope-4 (XW-4) CAS-10 is an 8U CubeSat, approx 228 x455x 100mm, with a mass of 12kg. The satellite will carry:

1. A VHF uplink and UHF downlink linear transponder with a bandwidth of 30kHz. This transponder will work all day during the life cycle of the satellite, and amateur radio enthusiasts around the globe can use it for two-way radio relay communications.

2. A camera, and the pictures it takes are stored in the flash memory on the satellite, we have designed a simple remote control system based on DTMF, and amateur radio enthusiasts around the globe can send DTMF commands to download the camera photos.

3. A CW beacon to send satellite telemetry data, which is also a feature that is widely welcomed by amateur radio enthusiasts.

4. A AX.25 4.8k/9.6kbps GMSK telemetry downlink

Planning a launch in November 2022 from Hainan Launch Center using a CZ-7 launch vehicle into a 400km circular 42.9 degree inclination orbit.

The IARU satellite frequency coordination panel report an application has been submitted for an amateur radio payload to be hosted on the Tiangong space station.

The coordination request says:

CSSARC is the amateur radio payload for Chinese Space Station, proposed by Chinese Radio Amateurs Club (CRAC), Aerospace System Engineering Research Institute of Shanghai (ASES) and Harbin Institute of Technology (HIT).

The first phase of the payload is capable of providing the following functions utilizing the VHF/UHF amateur radio band:
1. V/V or U/U crew voice;
2. V/U or U/V FM repeater;
3. V/V or U/U 1k2 AFSK digipeater;
4. V/V or U/U SSTV or digital image.

The payload will provide resources for radio amateurs worldwide to make contacts with onboard astronauts, or communicate with each other. It will also play a rule to inspire students to pursue interests and careers in science, technology, engineering and math, and to encourage more people to get interested in amateur radio.

Planning a launch from Wenchang in Q3 2022 to the Chinese Space Station.
