AMSAT-UK and AMSAT-NL are delighted to announce that a FUNcube communications package has been selected as a major payload for the Nayif-1 CubeSat mission.

Nayif-1 Mission PatchThis mission is intended to provide Emirati students with a tool to design and test systems in space. It is being developed by the Emirates Institution for Advanced Science and Technology (EIAST) in partnership with American University of Sharjah (AUS).

It is expected that this payload will provide a large amount of valuable environmental data from space together with  a new, enhanced, UHF to VHF linear transponder.

The AMSAT team will be working closely with the Emirati students, in collaboration with support partner, ISIS – Innovative Solutions In Space B.V. from the Netherlands, to develop this new system in time for the launch which is scheduled to take place towards the end of 2015.

This exciting news was announced on April 25, 2015 during the Dutch “Interessedag Amateursatellieten”  or “Satellite Interest Day” event in Apeldoorn.

More information, with details of frequencies and planned operating schedules, will be made available as soon as possible.

Ofcom considers 10.475 GHz and 47 GHz bands for 5G

Ofcom-logo-col-tThe Amateur Satellite Service allocations at 10.475 GHz  and 47.0 GHz are being considered by Ofcom for 5G use .

Ofcom has published an update on spectrum bands above 6 GHz that might be suitable for next generation mobile, often referred to as ‘5G’ – the fifth generation of mobile services.

This document summarises responses from Ofcom’s earlier Call for Input in January and sets out their current views on bands and next steps. The update identifies several bands in different parts of the 6 – 100 GHz range, including 10.475-10.575 GHz and 47.000-47.200 GHz, they believe are candidates for further study for use in the UK.

Ofcom’s goal is to have globally harmonised bands for next generation mobile services and is currently engaging with other administrations around the world, ahead of these services becoming commercially available in the next five to six years.

Consideration of these bands will now be taken forward in forthcoming international discussions, including the World Radiocommunication Conference-15 (WRC-15) at which the scope of a future WRC-19 agenda item on bands above 6 GHz will be considered.

This does not guarantee these bands will be adopted in the future and Ofcom do not rule out considering other options ahead of WRC-15, pending further research and development.

Kosmos-2504 pushes target off its orbit

Launch of Kosmos 2499Anatoly Zak reports on the maneuvers of Cosmos-2504 whose signals were detected by a Dutch amateur radio enthusiast Cees Bassa.

Cosmos-2504 was launched on March 31, 2015, at 16:47:56 Moscow Time from Site 133 in Plesetsk. Just hours later it was noted it was transmitting signals similar to previous maneuverable satellites — Cosmos-2491 (RS-46) and Cosmos-2499 (RS-47).

The request to power up the Ham Video system was added to the crew task list on April 16.

That means, that crew is invited to activate Ham Video as a free time activity. No precise day/time for this activity is fixed.

Please monitor the 2395 MHz at 2.0 Ms/s frequency and tell everyone as soon as you observe it.

This will be a period of blank transmission for testing and calibration. Please make maximum use of it.

With a heavy heart – G3CWV – SK

Clive Wallis G3CWV

Clive Wallis G3CWV

It is with great sadness that I have to inform you that I have just learnt of the passing of our dear friend Clive Wallis, G3CWV on 27th March 2015.

Clive has been a very staunch supporter of AMSAT from the very early days. Many will recall his intense interest and loyalty in following UOSAT-2/UO-11. He maintained a very comprehensive web site with details of the spacecraft’s activities. He wrote many articles for Oscar News about his activities. He attended many AMSAT-UK Colloquia.

He was awarded the Louis Varney cup for 2015 by the RSGB, and although he knew of the award before his passing, the formal presentation is not until 25 April.

His funeral is to be held on Wednesday, 22 April 2015 at 3.00pm at Christchurch, Bedford Road, Hitchin, Herts, UK. I am sure that his family would appreciate the presence of any AMSAT members who are able to be there.

We send our condolences to his widow, Janet.

RIP, Clive.

73s

FUNcube-1 (AO-73) Transmitting Again

FUNcube-1 (AO-73) is again transmitting telemetry. A restart took place during the 0930 UT pass over Europe.

The CubeSat had stopped transmitting at around 2018 UT on Wednesday, April 15.

The team is still investigating the situation, but have concluded from earlier telemetry analysis that it was safe to switch back to nominal operations.

During the 0930 UT pass over The Netherlands, Wouter PA3WEG commanded it back to nominal mode with full automatic mode switching.

At this time, there is no reason to believe this event was dangerous to the spacecraft, all systems were nominal and the battery is nearly full.

Many thanks for all the reports that the team have received.

ISS Ham Radio SSTV Video

On the weekend of April 11/12 Randy Hall K7AGE used his Arrow dual band J-Pole antenna, FT-817, Signalink USB interface and MMSSTV software to capture some great amateur radio Slow Scan Television (SSTV) images from the International Space Station (ISS).

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.

Local newspapers are generally only too glad to publish stories like this if someone takes the time to get in touch and tell them about it. Andrew made sure the newspaper was aware of his local clubs website URL and Facebook page enabling those reading the story to contact the club.

ISS SSTV and Packet Radio signals on the SUWS WebSDR

ISS SSTV and Packet Radio signals on the SUWS WebSDR

Martin Ehrenfried G8JNJ describes how he uses WebSDR’s to listen to ISS transmissions on 145.800 and 145.825 MHz. The SUWS SDR at Farnham can even receive the 143.625 MHz ISS comms channel.

We were treated to more Slow Scan Television (SSTV) pictures from the International Space Station (ISS) on the weekend of April 11/12.

During the Sunday evening passes a Cosmonaut suddenly decided to try some ad-hoc voice contacts between SSTV transmissions. Quite a few other stations were calling RS0ISS, but I didn’t hear any actual two-way exchanges. I made a very late, hurried and half-hearted attempt to call near the end of the pass, when my collinear antenna was most likely to be effective, but the ISS was very quickly out of range.

I was also monitoring the Russian VHF-2 comms frequency 143.625 MHz FM on the new extended 143 MHz band on the SUWS WebSDR in a second browser window, and heard a very short transmission from a Cosmonaut near the end of the UK pass. I suspect they were attempting to call Moscow as they started to come into range.

When the ISS dropped out on the SUWS WebSDR, I swapped over to the Russian http://sdr.22dx.ru/ WebSDR and heard some full contacts during a long pass over the Russian mainland.

With the exception of Asia (Bangkok SDR seems to be very deaf) it’s now possible to switch between WebSDR’s at different locations and catch just about all Amateur transmissions from the ISS. In fact it’s possible to set-up multiple browser tabs, one for each WebSDR and just leave them set on 145.800 MHz FM with squelch enabled, so that voice or SSTV traffic can be heard on each SDR in turn when the ISS passes into range.

These are two sound files captured on the WebSDR’s record function
