On March 25, 2016, the EO-79 SB/CW transponder was activated and will be available during Easter.

The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided by AMSAT-UK and AMSAT-NL and is a similar subsystem as on FUNcube-1, but without the telemetry downlink circuitry.

The current software running on EO-79 does experience occasional reboots. When these reboots happen, the transponder is automatically turned off and will have to be turned back on by a command station. The FUNcube team has selected a few command stations to do so, but be advised the transponder may be off.

TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD #    40025
COSPAR designator    2014-033-R

Frequencies:
Uplink: 435.035-435.065 MHz LSB
Downlink: 145.935-145.965 MHz USB

EO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds instead of 10 seconds. The beacon frequency is 145.815 MHz and consists of AX.25 frames on BPSK. more details about the downlink can be found on the ISIS HAM page at http://isispace.nl/HAM/qb50p.html

Just like FUNcube-1, the crystal oscillator circuits exhibit drift with temperature. This means manual tuning will probably work best.

Lastly, the commanding team availability will be limited over Easter, so please report the transponder being on or off on the status page of AMSAT: http://www.amsat.org/status/
It does not appear in the table, but it does in the reporting drop-down.

73 and have FUN

Tom Scott was given a tour of the Innovative Space Logistics clean room facility by Wouter Weggelaar PA3WEG. He got to see the FUNcube-1 Engineering Model and the new Nayif-1 CubeSat which carries an amateur radio SSB/CW linear transponder.

Welcome to Innovative Space Logistics, in the Netherlands: they invited me inside their clean room to see an actual CubeSat satellite that’s going into space soon! (No, this isn’t a sponsored video: I paid my own way there!) Go look at their site: http://isilaunch.com/ – and if you need to send something into space, get in touch with them!

The satellite model I’m holding is holding is the engineering model of FUNcube-1 and the flight satellite that I definitely couldn’t hold is Nayif-1, a cooperation between the Mohammed bin Rashid Space Centre and the American University of Sharjah.

Second Birthday of FUNcube-1

FUNcube-1 (AO-73) was launched into space two years ago on November 21, 2013.

We are delighted to be able to report that more than 900 stations, including many schools around the world, have received the telemetry from the spacecraft since launch. Our Data Warehouse is storing more than 750 MB of data from almost 1 million data packets. We are very grateful to everyone who has been contributing to the success of this mission. Please continue to keep the data flowing as it will provide a valuable resource for students in the future.

The stats continue – speeding along at around 17,500 mph, FUNcube-1, which had a launch mass of just 982 grams, has completed more than 10,500 orbits of the earth. This means a total distance travelled of more than 260 million miles.

All telemetry sensors continue to provide valid data, real time, whole orbit and high resolution channels alike. The flight code is really robust and we have only had three unexpected “events” since launch. Two of these we believe to have been caused by noise of the command receiver being incorrectly interpreted as a command and only one appears to have been caused by a RAM error. The battery and solar panels also continue to work perfectly and provide a very positive power budget.

We have sent out many Fitter messages for school and other similar events. On November 17, 2015 there was a demonstration at Thorne Green Top School in Yorkshire. Here is a report from Dave Ryan EI4HT/M0GIW:

FUNcube-1 Educational Outreach - Thorne Green Top School in Yorkshire

FUNcube-1 Educational Outreach – Thorne Green Top School in Yorkshire

Good Morning All  

Firstly -thanks to all for your help, we had a great morning at Green Top and the highlight was FUNcube.

I started with a slide show talking about communications from cave paintings all the way up to smartphones, we looked at space communications and travel from Sputnik to Astra and Apollo to the Millennium Falcon! We spoke about satellites and how they are used every day and how we all got to watch “I’m A Celebrity” via Satellite last night from Australia.

I brought in lots of props too, some old Motorola MX330 radios, some PMR 446, and a marine band radio .I also had a small model of a CubeSat that I knocked up over the weekend, I also passed around some NOAA images from last week’s Abigail storm and I had a few QSL cards from ISS and MIR from years ago when I lived in Ireland.  

The FUNcube pass was great, really strong signals, I had my turnstile and FCD set up and had audio through speakers and used the class projector to show Satpc32 and the Dashboard.  

There was a great buzz of excitement when we got the first packet and even more when the Fitter messages came through. The kids were fascinated to see the signal arrive just as the software predicted and then hear the telemetry and the decode.  

After the pass we were able to look at the Warehouse online and print off the QSL card and certificate.

 I didn’t get a chance to take many pics but Mrs Overson will update the School Blog and she took lots of pics.

Once again thanks to all at FUNcube, looking forward to Tim Peake on the ISS in the New Year and planning another visit to the School then.

Regards

Dave EI4HT / M0GIW

PS: I was back dropping my own kids off this morning and Mrs Overson told me they have printed a QSL card and Certificate for each of the students and they have used them for their class journals.

As well providing a great educational resource, FUNcube-1 operates at night and generally at weekends with the linear transponder active for radio amateurs to use for communications. The transponder continues to provide an excellent service. As users will be aware, the transponder uplink frequencies vary with receiver temperature. The RX temp telemetry channel is the best one to use for tracking this effect. This does make it quite difficult to use full computer control for transponder operations and we have already developed new oscillator circuits to improve this performance for future missions.

For the telemetry uplinked to the Data Warehouse, it is possible to download special Certificate or QSL Card here http://amsatuk.me.uk/on/funcube_qsl.php and, for transponder users, the “73 on 73 award” continues at https://amsat-uk.org/funcube/73-on-73-award/

The Nayif-1 CubeSat mission, which includes a full FUNcube payload, is expected to be launched into a similar orbit in the first half of next year and will provide an additional level of service to the community.

Meanwhile we hope everyone will continue to have fun with FUNcube-1!

Young people build antennas at Goonhilly

Young people build antennas at GoonhillyYear 11 students have been spending a week’s work experience at Goonhilly Earth Station learning about radio and satellite receivers. They researched and built a low-cost receiver using the FUNcube Dongle Pro+ Software Defined Radio.
