ISS SSTV reception on a portable setup using RTL-SDR

Standing in a car park, I was able to successfully receive the images using a handheld 3 element 144 MHz Yagi antenna connected to a RTL-SDR USB dongle.

The dongle was connected to Windows-8 tablet using a USB OTG cable.
I was running SDR# to listen and record the FM audio on 145.800 MHz.
I had a LNA connected between the antenna and rtl-sdr but since the the downlink from the ISS was quite strong it was probably not required.

Among the many radio amateurs receiving the pictures was Frank Heritage M0AEU. His station comprised a 5 element crossed Yagi on a Yaesu 5600B Az/Ele rotator, about 4 metres above the ground, interfaced with a LVB Tracker. Frank used the Ham Radio Deluxe satellite program (v5) for the tracking and a Yaesu FT736R feeding audio to the free MMSSTV software on a Dell laptop.

Martin Ehrenfried G8JNJ used the online SUWS Web-based Software Defined Radio (WebSDR) located near London to receive a number of images during the day. Martin made the 144 and 430 MHz helix antennas for the WebSDR which are optimized for satellite reception. The SUWS WebSDR is available for anyone to use.

Other images received by amateurs world-wide can be seen at http://www.spaceflightsoftware.com/ARISS_SSTV/

The next ISS SSTV transmissions on 145.800 MHz should start around 12:40 UT on Saturday, December 20 and end at 21:30 UT. It is expected the SSTV mode will be PD180 with 3 minute off periods between transmissions. A total of 12 different photos will be sent, each celebrating the 80th anniversary of the birth of Yuri Gagarin, the first human to orbit Earth.

The transmission will be mode using the Kenwood D710 transceiver located in the Russian Service Module. It is thought the equipment will be producing about 5 watts output which should provide a very strong signal.

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’s loudspeaker.

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 the 5 kHz deviation which is standard in much of the world.

Many FM rigs in the UK 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.

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. 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.”

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/

On November 19 Oleg Nizhnik gave a presentation on CubeSat amateur laser communication with Earth to Moon orbit data link capability.

In his paper Oleg says the available bands at 2.4 GHz and 5.8 GHz for amateur satellite communication are increasingly crowded. Higher frequency amateur bands meanwhile require uncommon microwave parts to implement transceivers, and working with 10 GHz or above require electric power typically not available in CubeSat. Therefore, to enable amateur Moon exploration, amateur laser communicator built of common, low-cost parts will help to extend amateur satellites operating range up to at least moon orbit.

The presentation was made in the 3rd Mission Idea Contest (MIC3) held during the 2nd UNISEC Global Meeting at Kyushu Institute of Technology, Kitakyushu, Japan, Nov. 19, 2014.

Amateur Satellite Seed Funding

AMSAT FOXOn December 2, 2014 the AMSAT-NA Board of Directors approved Technology Development Seed Funding.

As a part of AMSAT’s “Design The Next AMSAT Satellite” challenge, the Board of Directors approved $5000, within the 2015 engineering budget, to be used as seed money for future satellite development. Additional fund raising sources will also be investigated and pursued.

AMSAT President Barry Baines, WD4ASW, said, “We’re prepared to return to space starting in 2015 with a fleet of satellites that will equal, if not exceed, the performance, and availability to the average ham, of our previously popular AMSAT OSCAR 51. Meanwhile, we are preparing for the future looking to potentially leverage new technologies, to provide the best opportunities for enhancing amateur radio’s presence in space.”

Director Tom Clark, K3IO, noted the need for a defined future systems program. Tom said, “We saw a significant number of both new and old members who want to see the development of critical system elements for future opportunities by 2018-20. As I see it, critical ‘tall poles’ in applying potential technologies require significant work to begin now to ensure success.”

AMSAT is interested in supporting technology ideas that enhance the utility of using the CubeSat form factor to support more robust amateur satellite capabilities.  The scope of potential interest in not limited; some examples of  technology enhancement might include:

+ Microwave technology suitable for use in amateur spacecraft. This includes the need to identify optimum frequency bands.

+ Complementary, low-cost ground systems, including an effective ~1º antenna pointing system.

+ Define and develop optimum coding and modulation schemes for low power microwave use.

+ Attitude determination & control systems to point the spacecraft antennas towards the user while maximizing solar panel production.

Individuals interested in learning more about this initiative should contact AMSAT Vice President-Engineering Jerry Buxton, N0JY (n0jy at amsat.org).

Meanwhile, the development of AMSAT’s current series of the Fox-1 cubesats continues on schedule. AMSAT Vice-President of Engineering, Jerry Buxton, N0JY reported during the Board meeting that construction and testing of five Fox satellites is on schedule:

+ Fox-1A will launch on a NASA ELaNa flight during the 3rd quarter of 2015 from Vandenberg AFB,

+ Fox-1B will fly with the Vanderbilt University radiation experiments expected in 2016.

+ Fox-1C will launch on Spaceflight’s maiden mission of the SHERPA multi-cubesat deployer during the 3rd quarter of 2015. This flight was purchased by AMSAT.

+ Fox-1D is a flight spare for Fox-1C. If not needed as a spare it will become available to launch on any open launch slot which becomes available and be submitted in a CSLI proposal in 2015.

+ Fox-1E is built as a flight spare for Fox-1B but has been included in a student science proposal as part of the November, 2014 Cubesat Launch Initiative (CSLI) for an ELaNa flight slot. If selected the Fox-1B spare will fly as Fox-1E.
