Riaan Greeff ZS4PR has released a video of the demonstration of the FUNcube-1 (AO-73) CubeSat by Graham Shirville G3VZV to delegates at the IARU Region 1 Conference in September 2014.

Watch the video Graham G3VZV demonstrates FUNcube satellite

Mats SM6EAN has posted a brief report on the Swedish Amateur Radio Society (SSA) website about the FUNcube-1 CubeSat presentation at the IARU Region 1 General Conference in Varna-Albena, Bulgaria.

The following is translated from the original Swedish post.

After the session of the VHF, UHF and Microwave C5 Committee had completed the delegates were given two interesting presentations.

Graham Shirville G3VZV did a poolside demonstration of the FUNcube-1 satellite which was launched in November 2013. Using a computer, FUNcube SDR dongle and a turnstile antenna, held by Kjetil Toresen LA8KV, he received FUNcube-1 and displayed the telemetry data on the computer screen. The satellite’s telemetry beacon on 145.935 MHz was also heard using a handheld SSB receiver.

A presentation was also made about Hamnet which is being expanded, especially in Germany. Hamnet is a high-speed multimedia network and it was discussed whether and how IARU Region 1 could support the expansion of this network.

David Bowman G0MRF will be giving a presentation titled ‘A Beginners Guide to Amateur Satellites’ at the Sutton & Cheam Radio Society (SCRS) on Thursday, January 15 at 8 pm, visitors are welcome.

The SCRS newsletter says:

Last February, we had an excellent and well-attended talk by David Bowman – GØMRF on the topic of ‘The FUNcube Satellite Project’. The technology of satellite communication seems to have caught the interest of many of our members, but what has been missing at our meetings so far has been an illustrated talk on the basics of getting started.

David will be paying us a return visit on Thursday 15th January with a talk entitled ‘A Beginners Guide to Amateur Satellites’. This will cover the development of amateur satellite communications along with plenty of information on the necessary equipment to get started and the techniques employed.

Some amateur satellite operators have extremely sophisticated and no doubt expensive station set-ups,
however, it is possible to start off at a very basic level. All will be revealed at this meeting.

It’s always good to see a good turn-out of members and visitors at our meetings, so hopefully we can ‘kickoff’ 2015 with a packed clubroom. See you all on Thursday 15th.

John – GØBWV

The meeting will be held in the Vice Presidents’ Lounge, Sutton United Football Club, The Borough Sports Ground, Gander Green Lane, Sutton, Surrey, SM1 2EY at 7:30 pm for 8:00 pm.

Goonhilly Earth Station (GES) Ltd are transforming the BT satellite communications site at Goonhilly into a new Space Science centre.

The Goonhilly Satellite Earth Station is located on the Lizard Peninsula in Cornwall. It’s famous for many reasons, but perhaps most notably, for receiving, the first ever trans-Atlantic satellite TV images, broadcast by Telstar, on July 11, 1962. The impressive 25.9m dish called Arthur was used for that historic event.

The Register has published an article by journalist SA Mathieson following a recent visit to the site. This included seeing the AMSAT-UK ground station used to track the satellites FUNcube-1 and UKube-1 which both carry educational payloads developed by radio amateurs from the voluntary satellite organisations AMSAT-UK and AMSAT-NL. The station comprises an Asus PC with FUNcube Dongle Pro+ Software Defined Radio (SDR) and a turnstile (crossed dipoles) antenna.

SA Mathieson also visited another recent addition to the site, the radome used by the imaging start-up Planet Labs Inc to communicate with its constellation of  “Dove” CubeSats.

FUNcube-1’s Birthday

Hi Folks,

It seems amazing to us that FUNcube-1 – AO73, was launched nearly one year ago, in fact at 07:10 UTC on 21 Nov 2013. The very first signals were received by ZS1LS in South Africa at 07:37 UTC and he was even able to upload the resulting data to the Warehouse so the results could be seen immediately.

We are extremely happy to say that, since then, the satellite has been performing very satisfactorily, the battery voltage doesn’t drop below 8 volts, and becomes fully charged within about 7 – 10 minutes after re-entering sunlight from eclipse.

On Friday 21 Nov 2014, we will be celebrating the satellite’s first birthday. To mark the occasion, we will be activating the transponder earlier than normal – late on Thursday 20 Nov, so that it will be available for use during the whole of Friday. So please make as many contacts as possible through the transponder during Friday, FUNcube’s actual birthday. You are invited to make a note of any stations worked on this day, or any other comments on the FUNcube Forum. Please use the existing “FUNcube-1’s Birthday” topic, under the Welcome heading. The URL of the Forum is http://forum.funcube.org.uk/

Please also remember the ’73 on 73′ Award which is kindly being organised by Paul Stoetzer N8HM. See http://amsat-uk.org/funcube/73-on-73-award/ for more details.

We would like to take this opportunity of thanking all of our ‘users’, both those who download telemetry and forwarding it to the warehouse, and of course, all users of the transponder. This telemetry data is invaluable, both as an educational resource and to enable us to see how the spacecraft systems are performing and surviving. So far we have collected almost 400MB of unique data via stations from all around the world.

Of course we are hoping that the satellite continues to function nominally for several more years to come even though we may never reach AO7’s record!

AMSAT-UK upload JOTA greetings message to satellite

Wouter Weggelaar PA3WEG talking about FUNcube-1 to students at Abbeys Primary School in Bletchley

Wouter Weggelaar PA3WEG talking about FUNcube-1 to students at Abbeys Primary School in Bletchley

AMSAT-UK have uploaded a special Jamboree On The Air (JOTA) Greetings Fitter Message to the amateur satellite AO-73 (FUNcube-1).

Scouts and others can receive the message by downloading the Dashboard App software and listening to the beacon on 145.935 MHz (+/- Doppler) SSB.

What is a Fitter Message ?

‘Fitter’ is derived from ‘Twitter’. So it’s like a tweet, but via FUNcube.

It is a short (200 characters maximum) text-like message which can be uploaded to the satellite (by authorised ground stations), and transmitted several times every five minutes or so. It will continue to be retransmitted until such time as it is replaced by a new Fitter Message.
Links for tracking, downloads and other information can be found in the FUNcube-1 / AO-73 panel on the right-hand side of the AMSAT-UK homepage at http://amsat-uk.org/

From the early planning stage of the project we decided that we would make telemetry information from the AO-73 (FUNcube-1) CubeSat available to end users.

Since deployment the FUNcube Data Warehouse has displayed the latest data:
• Reatime
• Whole Orbit
• High Precision
• Fitter Messages
and of course the upload rankings. Additionally we have made available small csv files for WOD and HiRes.

Starting October 14, we will be making all captured WOD available as weekly csv files.

Please see: http://warehouse.funcube.org.uk/wod.html?satelliteId=2 for the link to the downloads page. It currently up to 26/6/2014 (32 files)

The files are on average:
• 9706 lines (expected 10080) ~ 96.3% capture
• 905 KB

We will play catch up over the next few days and then automate the process.

It it really intended for consumption by an analytical suite such as MatLab, or a DIY one, in a language of your choosing. However, it can be simply graphed in Excel or Open Office Calc.

Feedback would be appreciated.

Enjoy!
