Slow-scan television (SSTV) transmissions are planned from the International Space Station (ISS) on February 13-14, 2017.

The SSTV images will be transmitted as part of the MAI-75 Experiment on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-180 SSTV format.

The MAI-75 activities have been scheduled for the Russian crew on Monday, February 13 from 09:25-18:00 GMT and Tuesday, February 14 from 11:25-16:30 GMT.

Note the ISS transmissions on 145.800 MHz FM use the 5 kHz deviation standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try the wider filter.

Tancredo-1 TubeSat Video

Ubatubasat TeamPaulo PV8DX has released a video describing the new TubeSat Tancredo-1 and showing reception of the 437.200 MHz downlink by Drew KO4MA.

Tancredo-1, mounted in a TuPOD Deployer, was ejected from the International Space Station on January 16, 2017. The satellite is a STEM project built by middle school students at Escola Municipal Tancredo Neves school in Ubatuba, in the state of Sao Paulo, Brazil.

The video is in Portuguese but try enabling the YouTube Closed Caption subtitles and use the Auto-translator to get English.

Masahiro Arai JN1GKZ reports that six CubeSats delivered to the International Space Station by the HTV-6 will deploy from the ISS using the new JEM Small Satellite Orbital Deployer (J-SSOD) on Monday, January 16.

JAXA ISS CubeSat Deployment 2017-01-16The new J-SSOD has four satellite install cases. One satellite install case has 3U space, so the new J-SSOD could deploy twelve 1U CubeSats at a time.

The six CubeSats are installed as follows:

Case    CubeSats
#1        three 1U CubeSats ITF-2、WASEDA-SAT3、FREEDOM
#2        one 3U CubeSat    EGG
#3        one 2U CubeSat    AOBA-VELOX3
#4        one 3U CubeSat    TuPOD (including Tancredo1 and OSNSAT)

ITF-2、WASEDA-SAT3、AOBA-VELOX3, TuPOD and Tancredo1 have amateur radio downlinks.

#1 and #2 will be deployed at 0900-0930z January 16, #3 and #4 will be 1030-1100z.

Live broadcast will start at 0850z on the JAXA YouTube channel.

Making contacts through the ISS APRS UHF Digipeater

John Brier KG4AKV has released a video showing his contact through the International Space Station packet radio digipeater on 437.550 MHz FM (+/-10 kHz Doppler shift).

This was my second contact through the ISS digipeater. I actually contacted the same station I contacted in this video, W8LR, three days before, but I wasn’t recording any video.

For this video I recorded the audio from my Kenwood TH-D72a and later played it back to Soundmodem+UISS. Soundmodem decodes many more packets than my radio does. I made a screen capture of UISS and its map so you can see the complete details of every received packet.

Another thing this video shows is how hard it can be to track a near overhead pass (close to 90 degrees elevation). When I was beginning in satellites I only tried to work overhead passes because I knew the signal would be strongest when the satellite was closest to me. While that is true, the closer the satellite is to you the faster its relative speed is. When it passes overhead it switches from coming towards you to going away from you very fast, and drops 10s of degrees in seconds. That makes the satellite very easy to lose track of.

In this video I got distracted while changing settings on my radio and lost the ISS after it went overhead. It didn’t help that I was using a tripod for the first time. I prefer to hold the antenna in my hand precisely because I find it’s easier to track, as I can make quick adjustments and listen for the signal going up and down. To control the radio for packet, it helps to have two hands.

Tomsk-TPU-120 CubeSat to deploy during EVA

The amateur radio CubeSat Tomsk-TPU-120 may be deployed during a Russian spacewalk (EVA) in July 2017.

The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and is the world’s first space vehicle with a 3D-printed structure. It was launched from Baikonur in Kazakhstan to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel.

It will be deployed by hand during a Russian spacewalk, which is why unlike other CubeSats this one has a handle. The call sign of the satellite is RS4S.

According to Alexey Yakovlev, head of the Tomsk Polytechnic University’s Institute of High Technologies, the 3D printed satellite is something of a landmark for additive manufacturing, being the first example of a fully 3D printed satellite: “The Tomsk-TPU-120 is the first such project in the world, in which the entire casing of a satellite is fully 3D printed using dynamic modeling,” Yakovlev recently told Sputnik. “The combination of these technologies can significantly reduce the development time and the number of full-scale tests, find new engineering solutions, and reduce the project’s cost.”

In May 2016 the Tomsk Polytechnic University celebrated its 120th anniversary. As part of the celebrations on May 10/11 the Tomsk-TPU-120 was activated in the ISS and transmitted a greeting to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.

The greeting message was transmitted once a minute on 437.025 MHz FM. A Kenwood transceiver on the ISS provided a cross-band relay, re-transmitting the signal on 145.800 MHz FM.

Middle School Students’ Tancredo-1 TubeSat Scheduled for Launch

Ubatubasat Team

Ubatubasat Team

The Tancredo-1 satellite, a small TubeSat built by middle school students in Brazil, is scheduled to be sent to the International Space Station on December 9, 2016. The satellite will be sent to the ISS inside the TuPOD TubeSat deployer onboard JAXA’s KOUNOTORI6 cargo ship (HTV-6 mission). The TuPOD is expected to be ejected into space by the J-SSOD satellite deployer on December 19th and on December 21st, Tancredo-1 is expected to be finally ejected from the TuPOD into space. Once in space, Tancredo-1 will start transmitting telemetry data.

Tancredo-1

Tancredo-1

Tancredo-1 is the first satellite of the Ubatubasat project, a STEM project idealized by Prof. Cândido Oswaldo de Moura at Escola Municipal Tancredo Neves public school in Ubatuba, state of Sao Paulo, Brazil. The project is supported by the Brazilian Institute for Space Research (INPE) and the Brazilian Space Agency (AEB). Tancredo-1 will initially have the same orbit as the ISS, but it will slowly drift with time and will eventually reenter in the atmosphere and burn.

The Ubatubasat project team and AMSAT-BR would like to kindly request radio amateurs around the planet to monitor and report any signals heard from Tancredo-1. Please send any reports (audio, AX.25 KISS files, etc) to py2sdr@gmail.com

Tancredo-1 will transmit on 437.200 MHz using 1200 bps AFSK AX.25.
