ARISS SSTV Award

Hello,
Thank you for submitting your report.

The ARISS Series 31 images will consist in 12 pictures commemorating wants Cosmonauts Day, the 100th anniversary of liquid-fueled rockets, the inaugural Space Shuttle launch and SuitSat!
The certificate shows people associated with these events. From left: Konstanin Tsiolkovsky was a visionary and theoretician. He focused on the mathematical foundations of space flight, developed the rocket
formula (the Tsiolkovsky equation), and designed theoretical models of liquid-fuel rockets.
Robert Goddard – He was an engineer and practitioner. He focused on construction and testing. He launched the first liquid-fueled rocket in history in 1926.
The crew of the first space shuttle flight: John Young and Robert Crippen. The STS-1 mission aboard the Space Shuttle Columbia launched on April 12, 1981.
Exactly 20 years earlier, the first man in the world, Yuri Gagarin, made the first space journey on board the Vostok-1 spacecraft. 20 years have passed since another important event for radio amateurs.
SuitSat! (RadioSkaf) – a worn Russian Orlan spacesuit with an attached amateur radio transmitter. It was assembled by the crew of the Soyuz TMA-7 mission residing at the International Space Station. It was
launched into orbit on February 3, 2006, and operated for six months. It burned up in Earth’s atmosphere on September 7, 2006.

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). The
primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and
amateur radio.

TEN-KOH-2 Update

The signal from Ten-Koh2 is weaker than expected.
At our ground station, we are monitoring telemetry(voltage, temperature etc.) via the CW beacon. Reception reports via SatNOGS are very helpful. We would appreciate your continued support in receiving signals.

Currently, only the CW signal on 435.860 MHz is active. It is transmitted every 90 or 180 seconds depending on the satellite status.
Thank you very much for your cooperation!!

UO-11 telemetry beacon

 

..and the “Grand Dame” of digital communication experiments is celebrating its 40th anniversary these days.

On March 1, 1984, the second satellite designed and built by the University of Surrey’s Spacecraft Engineering Research Group—USAT in the UK, UoSAT-2 (UO- 11) was launched on a Delta rocket from the Western Test Range at Vandenberg Air Force Base
Among its many experiments, UoSAT-2 carried the Digital Communications Experiment, which was the first use of amateur radio store&forward techniques with Low Earth Orbiting Satellites
In 2008 it was determined that there was no viable battery backup functioning, only the solar panels were available to provide power. With the watchdog timer and eclipse schedule during orbits, the satellite has a 20 day cycle of 10 days on and 10 days off.

The older satellite radio amateurs will surely fondly remember the many wonderful hours we spent with UO-11. That makes it all the more wonderful to still receive the familiar signals today:

FO-29 is back

Mike san,

Thank you for providing the S/W regarding the shading and sunlight of FO-29. I was able to predict it accurately. Also, thank you for the CW telemetry information.

I will inquire with JARL whether it is possible to issue a QSL, but it is probably discontinued. This year, there is full sunlight for about half a year. The old lady will celebrate her 30th birthday this August.

Thank you very much, Mike san.

73’s  JA1OGZ Akira.
