ISS SSTV Image 2 of 12 received by Andrew Garratt M0NRD April 11, 2015

AMSAT-UK member Andrew Garratt M0NRD got some good publicity for Amateur Radio from the recent ISS Slow Scan Television transmissions.

The SSTV pictures were sent in celebration of Yuri Gagarin becoming the first human to reach space, on April 12, 1961. The Russian cosmonauts on board the station transmitted images from Gagarin’s life which were received by radio hams worldwide. Andrew said he hoped it would encourage more people to become interested in radio.

The Russian Federal Space Agency (Roscosmos) has announced another round of amateur radio Slow Scan Television (SSTV) activity from the International Space Station (ISS). It will commemorate the anniversary of the first human spaceflight by Yuri Gagarin which took place on April 12, 1961.

Continuous operation, using the call sign RS0ISS, is expected to start at 1000 UT on Saturday, April 11 and continue until 2130 UT on Sunday, April 12.

Twelve different images will be sent on 145.800 MHz FM using the SSTV mode PD180, with a 3-minute off time between transmissions.

One of the photos shows the commemorative diploma created by PZK, the national Polish Amateur Radio society, on the occasion of the 80th anniversary of the birth of first cosmonaut Yuri Gagarin.

The equipment used will be the Kenwood D710 transceiver located in the Russian Service Module. It is thought the equipment may be producing about 25 watts output which should provide a very strong signal.

Plans are being discussed for transmitting new images from space enthusiasts around the world in the coming months. Additional details will be released.

The images received by amateurs world-wide during previous transmissions can be seen at http://www.spaceflightsoftware.com/ARISS_SSTV/ and you are invited to upload any pictures you receive during the upcoming transmissions.

In the UK newspaper the Daily Mail, Jonathan O’Callaghan wrote about how 22-year-old Radek Karwacki, an AMSAT-UK member, received pictures from the ISS using a £10 ($15) RTL-SDR dongle and a dipole antenna, see http://amsat-uk.org/2015/02/04/iss-sstv-in-uk-press/

All you need to do to receive SSTV pictures direct from the space station is to connect the audio output of a scanner or amateur radio transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM. You can even receive pictures by holding an iPhone next to the radio loudspeaker.

On Windows PC’s the free application MMSSTV can be used to decode the signal, on Apple iOS devices you can use the SSTV app for compatible modes. (Note: see comments below about MMSSTV adjustments which may be needed to reduce picture slant)

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld with a 1/4 wave antenna will be enough to receive it. The FM transmission uses 5 kHz deviation which is standard in much of the world apart from the British Isles and Europe where 2.5 kHz deviation is more common.

Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the wider deviation filters. Handhelds all seem to have a single wide filter fitted as standard.

The ISS Fan Club website will show you when the space station is in range.

Paul Turner G4IJE, co-developer of the SSTV PD modes, says regarding the MMSSTV PD180 mode: “Don’t forget to either enable “Always show RX viewer” or use the “Picture viewer” (magnifying glass icon) to show the picture at its real resolution of 640 x 496. If you just view as normal you will only see 320 x 248 resolution, which kind of defeats the object of using a high resolution mode.”

In Option > Setup MMSSTV (O) > RX make sure Auto-slant is ticked.

On the AMSAT-BB Rick W2JAZ and Alan WA4SCA comment on the need to set the MMSSTV sound card setting to 48 kHz instead of the default 44.100 kHz
• Options
• Setup
• Misc
• Then the Clock section at the bottom of the page

The MMSSTV default setting may need to be set to 24000 (exactly half of the sound card setting). You then should get good clean images.

The sound card adjustments will vary slightly depending on the version of the OS you are running, but usually will be under the advanced properties for the device. You can probably use a higher sampling rate for the sound card so long as it is a power of 2 multiple (2,4,8, etc) of the value in MMSSTV. For instance 192k (8x) has no issues. The same applies to most similar software.

You can receive the SSTV transmissions online using the SUWS WebSDR remote receiver located near London along with the MMSSTV software http://amsat-uk.org/2014/08/15/suws-websdr-moves-to-new-site/

The Japanese Space Agency, JAXA, have released a video showing the deployment of the Brazilian amateur radio satellite AESP-14 from the International Space Station (ISS).

The AESP-14 is a 1U CubeSat developed by undergraduate and graduate engineering students at the Technology Institute of Aeronautics (ITA) in Brazil. The satellite’s primary mission is to test the various subsystems in the space environment.

The satellite was sent to the ISS as cargo on the SpaceX Falcon 9 mission CRS-5. Launch had been scheduled for December 16, 2014 but was postponed three times and it wasn’t until January 10, 2015 that the launch eventually took place. AESP-14 then awaited deployment from the ISS by the JEM Small Satellite Orbital Deployer (J-SSOD) which is in the Japanese Experimental Module, Kibo.

The deployment took place around 1250 UT on Thursday, February 5. The AESP-14 telemetry beacon had a power output of 500 mW and used AX.25 with 9600 bps GMSK modulation (G3RUH standard) on 437.600 MHz. It should have started transmitting 30 minutes after deployment but as of March 30 nothing had been heard. It may be the battery did not survive several months without being recharged or the antenna may have failed to deploy.

Astronaut issues challenge for UK students to “make that call”

Tim Peake KG5BVI, the first British ESA astronaut, has issued an invitation to UK school pupils to contact him via amateur radio whilst he is in space.

Tim will launch to the International Space Station (ISS) in November of this year and will spend 6 months working and living on the ISS. Thanks to a collaboration between Amateur Radio on the International Space Stations (ARISS), the UK Space Agency, the Radio Society of Great Britain (RSGB) and the European Space Agency (ESA), UK school pupils will be able to contact him whilst he is on board the ISS via a scheduled amateur radio link-up.

The Kent and Sussex Courier newspaper reports a picture from space has been decoded by an over-the-moon radio amateur from Tunbridge Wells.

Colin Bowman M0NLP spoke to his local newspaper after receiving a Slow Scan TV (SSTV) picture from the International Space Station (ISS) and in doing so gained some good publicity for the hobby.

He told the Courier: “I went mad when I realised I had decoded an entire picture.”

“I had to e-mail my children straight away, though, as they are both licensed amateurs as well and my daughter has just started a new job in the space industry in Turin.”

Danish astronaut Andreas Mogensen completed his amateur radio license class on February 23 and passed his exam on February 25. He has been assigned the callsign KG5GCZ.

Andreas was selected as an ESA astronaut in May 2009 and completed the astronaut basic training programme at the European Astronaut Centre in Cologne, Germany in November 2010. Since completing the astronaut basic training programme, Andreas has been trained and certified as a private pilot by the Lufthansa flight school and is trained and qualified for spacewalks using both the American EMU suit and the Russian Orlan suit.

In July  2009 he attended the AMSAT-UK International Space Colloquium in Guildford where he described to delegates the astronaut selection process. This year it was announced he would be on the same 10-day mission to the International Space Station (ISS) as the UK’s Sarah Brightman.

He will be the first astronaut of Danish nationality to go to space and will launch with Sarah on a Soyuz TMA-18M spacecraft in September 2015.

ISS SSTV in a Brazilian School

Paulo PV8DX of AMSAT-BR turned the recent Slow Scan TV transmissions from the International Space Station (ISS) into an education outreach opportunity for amateur radio.

On Monday, February 23, 2015 at the Gonçalves Dias school he explained amateur radio to the students and demonstrated receiving an ISS SSTV picture on 145.800 MHz FM.

The ISS pass he received did not produce a strong signal and only part of the picture was captured but as can be seen from the video the students were enthusiastic and excited to be receiving a signal from space.

Paulo expressed the hope that the ISS will send images on school days more often.

Space Station SSTV and Packet Radio via SUWS WebSDR

Martin Ehrenfried G8JNJ reports excellent SSTV and Packet Radio signals from the International Space Station (ISS) using the online SUWS WebSDR.

144 MHz prototype helix antenna

144 MHz prototype helix antenna

The omni-direction helix antennas at the WebSDR were designed with high elevation satellites in mind. Conventional antennas concentrate the radiation pattern towards the horizon resulting in weaker signals when a satellite is above 15 degrees elevation. Comparisons with other WebSDRs show the SUWS antennas provide a 6 to 10dB better signal to noise ratio on similar passes.

Martin says: “I had been experimenting with single turn ‘twisted halo’ design, and decided to try stacking them to see if I could achieve more gain. Modelling suggested that a stretched 3 turn helix with a helix circumference of approx 1/2 wave length and an overall length of 1/2 wave at 70cm, and fed with a gamma match at the centre would offer reasonable gain, an omni-directional pattern and mixed polarisation.”

You can use the free online SUWS Web Software Defined Radio from your PC or Laptop to receive the ISS and the many amateur radio satellites transmitting in the 144-146 MHz or 435-438 MHz bands. It also provides reception of High Altitude Balloons in the 434 MHz band and coverage of the microwave 10368-10370 MHz band.

The SUWS WebSDR is located at Farnham not far from London, 51.3 N 1.15 W, listen to it at http://websdr.suws.org.uk/

Full details of the antennas are available at http://g8jnj.webs.com/currentprojects.htm
