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:

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.


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 and, for transponder users, the “73 on 73 award” continues at

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!

AO-85 Commissioned


AO-85 (Fox-1A) Flight Unit

AO-85 has been formally commissioned and turned over to AMSAT-NA Operations, who are now responsible for the scheduling and modes.

The following guidelines are provided for users:

Uplink power should be on the order of minimum 200 W EIRP for full quieting at lower antenna elevation angles. Your mileage may vary. With an Arrow, 5 W has been used successfully to make contacts.

Polarity is important. The satellite antennas are linear. So, if you are using linearly polarized antennas, you will need to adjust throughout the pass. Full duplex operation facilitates these adjustments while transmitting and is highly recommended.

The downlink is very strong and should be heard well with almost any antenna.

Downlink audio is 5 kHz deviation, as expected. Many will perceive that the audio is “low.” This is an effect of the filtering below 300 Hz, which provides for the DUV telemetry, coupled with any noise on the uplink signal resulting from lack of full quieting or being off frequency. That makes for less fidelity than a typical receiver in terms of audio frequencies passed.

Transmit (downlink) frequency varies with temperature.  Due to the wide range of temperatures we are seeing in the eclipse cycle, the transmitter can be anywhere from around 500 Hz low at 10°C to near 2 kHz low at 40°C.

Receive frequency has been generally agreed to be about 435.170 MHz, although the AFC makes that hard to pin down and also helps with the uplinks that are off frequency.

Probably the most notable observations about AO-85 are an apparent lack of sensitivity and difficulty in turning on the repeater with the 67 Hz CTCSS when it is not yet activated, or holding it on by the presence of the CTCSS.  We have determined a probable cause for the sensitivity issue and while that can’t be fixed on AO-85 we are taking steps to prevent similar issues on the rest of the Fox-1 CubeSats.  The tone detection threshold along with the receive sensitivity issue makes it hard to bring up the repeater.  This is being addressed by adjusting the values for a valid tone detection in the other Fox-1 CubeSats now that we have on orbit information about temperatures and power budget. Full details will be in the Nov/Dec AMSAT Journal.

It is important to remember that science is the reason behind the Fox-1 satellites. Not only does science help with the launch cost, it provides a great amount of educational value both from the science payload and in amateur radio itself. The data-under-voice (DUV) telemetry is an excellent way to provide the science without sacrificing the use of the satellite for communications, which would be the case if higher speed downlinks were needed. DUV provides constant science as long as the repeater is in use, which in turn provides more downlink data for the science – a mutually beneficial combination.

Fox-1A is AMSAT-NA’s first CubeSat. Many new techniques are incorporated and lessons will be learned, as with any new “product.” The Fox-1 Project is a series of CubeSats. A total of five will be built and flown. Launches are scheduled for three more, and a new NASA CubeSat Launch Initiative proposal will be submitted for the fifth. We will incorporate changes from what we learn in each launch, to the extent possible, in subsequent Fox-1 CubeSats.

Of the four NASA sponsored CubeSats on the ELaNa XII launch October 8, we are sad to report that ARC1 was never heard from and BisonSat was lost after a few weeks of operation. AMSAT extends our deepest sympathy to the people who worked so hard on these projects. To our members, we want to say that the Fox Team is very proud and pleased that our first CubeSat is very successful and hopefully will be for some time.

Nayif-1 at YouthConnect

Nayif-1 at YouthConnectYouthConnect is an initiative led by the Expo 2020 UAE team and is catered specifically for the Youth of today. The Nayif-1 team took part in the event by throwing a workshop titled “Introduction to Cubesatellites.”

What's a CubeSat ? Brainstorming Session

What’s a CubeSat ? Brainstorming Session

YouthConnect is the first in a long-lasting and wide-ranging series highly interactive forums designed by youth for youth. The inaugural event took take place on Saturday, November 14, 2015. This first interactive, full-day forum, part of a far wider programme to talk to the younger members of society, was open to all UAE residents between the ages of 18-25.

“From our earliest days conceiving Expo”, says Her Excellency Reem Al Hashimy, UAE Minister of State and Director General of the Bureau Dubai Expo 2020 “we were determined to put our youth at the heart of our plans. It is these young men and women who will be representing and leading our nation in the years to come. So it is important that they contribute to these events and decide what they want to see and do on the day.”

Nayif-1 was built by students at the American University of Sharjah, UAE, in partnership with the Mohammed bin Rashid Space Centre. The nanosatellite will incorporate a novel autonomous attitude determination and control system. This will be the first flight of this system. Additionally it will carry a UHF to VHF linear transponder that will have up to 0.5 watt output and which can be used by Radio Amateurs worldwide for SSB and CW communications.

A launch is planned for the first half 2016 on the SpaceX Falcoln 9 SHERPA mission with deployment into an elliptical, sun synchronous, Low Earth Orbit (LEO) of about 450 by 720 km.

DeorbitSail Update and Initial Camera Image

DeorbitSail project team members

Chris Bridges 2E0OBC of the Surrey Space Centre provides this update on the status of the DeorbitSail Cubesat.

Dear AMSAT Community,

We would like to express our gratitude for your cooperation in the DeorbitSail project, and update you on the status of the mission.

As you know the DOS mission was launched on 10th July. After 4 months of operations, the satellite is healthy and stable, although unfortunately we have not been able to meet all of the mission objectives. Initial contact with the satellite was established relatively smoothly and we received a lot of good data, both through our own ground station but also via the network of you radio amateurs who have been very generous with your time and help.

We achieved a power stable state early on, with good comms (uplink and downlink) established within the first few days. We deployed the solar panels successfully, and managed to return to a good and stable power state after deployment. The ADCS has been challenging from the start, and continues to be challenging – we have struggled to accurately determine the satellite tumble rate and get it under control  (more detail on that is included below). We know that the satellite has seen some very high spin rates for various reasons, including some inherent design/magnetic characteristics which have become apparent.

Despite many attempts, we have unfortunately not been able to deploy the sail, and having recently thoroughly analysed and investigated the possible causes, mission events and ground test data and history, we are now reaching the conclusion that achieving successful sail deployment is very unlikely. Again there is more detail on that in the main body of text below.

We thank you for your patience and would like to apologise  for not keeping you updated on mission progress as often as we’d hoped. The operations phase has been a learning and sometimes stressful experience for all of the team at SSC, with a lot of head scratching and sleepless nights involved.



Here is some more detailed information regarding what progress and achievements have been made during the operations to date.

• After the launch on the 10th of July, and the first week in orbit, with a power safe and healthy satellite, the operation passed from the LEOP phase to the ADCS Commissioning phase. This second phase was estimated to last between three and four weeks; this proved to be optimistic.

• Although the spin up of the S/C was much higher than expected and saturated the sensors, the SU simulations and the available data suggested a large Z-spin rate on DOS which was confirmed by the B-field and MEMS magnetometry measurements. To induce a bigger difference in the Moments of Inertia (MoI) of the two non-longitudinal axes, the decision was taken to deploy the solar panels. This operation was performed the 10th of August.

• More than a month after the launch the satellite was really healthy, power safe and with great comms through newly developed software defined radio and database backend operations. Although the stabilization wasn’t achieved even with the solar panel deployment, at one month from the launch the team decide to proceed with  the sail deployment.

• This decision was agreed with DLR that confirmed that tumbling rates were no issue for the sail deployment, because the Moments of Inertia increase rapidly slowing down the tumble rate. DLR has performed a deployment test on Gossamer while tumbling before coming to this opinion.

• On the 15th of August, the first attempt for sail deployment was performed, the command was sent and the acknowledgement from the S/C was received, but no current was drawn from the boom deployer motor. Multiple experiments were performed to try and determine the cause of sail deployment failure.

• At this point, after a thorough investigation, the most plausible hypothesis and justification seems to be a physical disconnection of the motor cables. (Note that after the vibration test, it wasn’t possible to physically inspect the connection due to the design itself of the S/C)

Our simulations showed that with the actual configuration (deployed solar panels, undeployed sail) the decay time should be 20 years circa.

The aim now is to exercise and exploit the parts of the satellite that are working, and gain more confidence and experience with the SU ADCS system, the ISIS TRXUV and solar panels, and the SSC SDR groundstation and database tools to explore better the interaction of the panel circuitry with the attitude stabilisation. That will allow us to improve our performances in the next missions.

From here, the team have worked hard to take images of the Earth and via SU’s CubeSense camera – which we are delighted to show you today. This would not be possible without the dedication from the SSC team here and, of course, the amateur telemetry you kindly send us. We are going to continue imaging and testing at higher resolutions too so watch this space.

We thank you for all the support.

Wouter Weggelaar PA3WEG has provided this update on the status and plans for QB50p1 – EO-79.

Earlier testing campaigns indicate that the AMSAT-UK/AMSAT-NL transponder on board of this spacecraft is in good health. We have activated the transponder on various occasions for testing purposes.

At the moment we believe the power system is capable of sustaining transponder operations indefinitely. ISIS (the satellite designer and operator) still needs to write and apply a software patch that would keep the transponder running. The current logic in the satellite will switch off the transponder if a reset occurs of the On Board Computer or power system.

Efforts are being made to allow usage of the transponder in the mean time and also allow select command stations to take the satellite out of safe mode if it does reset. ISIS will continue to monitor all telemetry and the satellites health.

The precursor satellites have gathered valuable data about the sensor payloads, and the lessons learnt are being implemented in the flight units for the QB50 main mission.

We will still have to wait until procedures are in place and the activation is cleared by the operator and owners of the satellite, but we are nearly ready for the activation of another transponder!

Transponder activations will be announced on the AMSAT Bulletin Board.

On behalf of AMSAT-NL and the ISIS operations team I would like to thank the community for supporting our mission and thank you for your patience.

With the help of amateur radio operators, Aalborg University engineering students have established two-way communication with their home-built, ESA-sponsored satellite AAUSAT5.

The European Space Agency (ESA) report:

Deployment of AAUSAT5 and GomX-3 from the ISS Kibo robot arm - Credit NASA, NanoRacks

AAUSAT5 was launched from the International Space Station on October 5, 2015. Following initial difficulties in establishing a two way communication link with the satellite from the control centre in Aalborg and attempts to improve the ground station performance, the investigation revealed that the northern location of Aalborg, relative to the satellite’s orbit, was a contributor to the communication issue. Therefore the project team reached out to ham operators in more southern locations in Europe for help.

Aalborg University sent special equipment down to a German ham radio operator. From his location south of Frankfurt, this operator now acts as the relay station between the student’s control centre in Aalborg and the satellite whenever it passes over Europe. In this way, communication has been established.

Several of the ham radio operators who assisted the AAUSAT5 team have been given the status of external crew members. They are: Mike Rupprecht DK3WN (Germany), Lars Mehnen OE3HMW (Austria), Jan Van Gils PE0SAT (The Netherlands) and Lars-Christian Hauer DJ3BO (Germany).

“Two-way communication is a very big step for the mission. AAUSAT5 can easily be heard in Aalborg via equipment in Germany, and the satellite can receive and respond to commands sent from Aalborg. So we’ve been able to reprogramme the radio transmitter and receiver on board as a first step towards optimizing the connection,” says Associate Professor Jens Dalsgaard Nielsen OZ2JDN, who is supervising the team.

“We celebrated with champagne when we managed both to hear the satellite and send commands to it,” says fourth-year engineering student Anders Kalør from the AAUSAT5 team. Although he admits it was disappointing when they did not initially hear from the satellite, Kalør says that the team never lost heart.

In some ways the communication challenges proved to be a blessing in disguise, forcing the team to work even harder and learn even more. “I’ve learned more about radio communication the past three weeks than in the entire rest of the programme. So as training it has been perfect.” says team member Lasse Bromose.

AAUSAT5, a small satellite of 10cm x 10cm x 10cm with a mass of 1 kg, is one of the first two ESA satellites ever sent into orbit directly from the International Space Station, the other satellite was GomX-3.

AAUSAT5’s main mission is to test an improved receiver for detecting Automatic Identification System signals emitted by ships. The next major goal is to determine whether the satellite is capable of registering ships as planned and, if so, whether it can then relay the ships’ positions down to the control centre.

AAUSAT5’s deployment could be the first in a new programme offered by the ESA Education Office called Fly Your Satellite from the ISS!

UKube-1, the UK Space Agency’s first national spacecraft, has now completed its nominal mission following over 14 months of operations. Discussion is underway with AMSAT-UK about the possibility of taking over UKube-1 operations to continue its educational and outreach activities.

UKube-1 CubeSat installed in Deployment Pod

Launched in July 2014, UKube-1 is a technology demonstration mission with a broad set of objectives aimed at attracting and training future generations of engineers, encouraging collaboration across sectors and institutions, fast tracking space technology development and engaging with students.

As a 3 unit CubeSat (30x30x10cm), flying 4 main payloads, with all the key subsystems of much larger satellites, UKube-1 remains one of the most advanced CubeSats ever built. Despite some technical challenges in orbit, the mission has achieved a range of milestones including:

• delivery into the correct planned orbit (around 650km, sun-synchronous)
• successful deployment of solar panels and antenna
• good battery health
• slow spin rate measured
• uplink and downlink capabilities checked, including Large Data Transfer, downlink at 3 speeds, and redundant communications mode
• all core payloads commissioned and data collected for each
• on-board camera technology successfully tested
• data downlinked from multiple ground stations across the globe

UKube-1 has also helped maintain the UK’s leading position in the CubeSat sector. Participation in the mission placed Clyde Space in an excellent position to capitalise on the fast growing global nanosatellite market. The company has experienced 100% year on year growth, both in turnover and employees, as a direct result from involvement in UKube-1, and is firmly established as a global leader.

Mark McCrum, Bright Ascension Ltd, said:

“UKube-1 provided us with an invaluable opportunity to gain flight heritage for our software technology and to get deeply involved in the operation of a complex CubeSat mission. It gave a huge boost to our credibility as a space software provider and has been instrumental in winning further work.”

Craig Clark, CEO Clyde Space Ltd, said:

“UKube-1 represents a pivotal achievement in the development and growth of Clyde Space. The project moved the company from being a spacecraft subsystems supplier to providing full missions for our customers. To give some context to the extent that Ukube-1 has had to our business, Clyde Space has more than quadrupled in size in the last 3 years and there are currently over 60 CubeSats planned through production here in Glasgow over the next 18 months. The return on investment for Ukube-1 in terms of jobs and export sales for the UK has been outstanding and is a great example of industry and the UK Space Agency working together to put the UK at the forefront of global space technology.”

Professor Andrew Holland, Open University, added:

“Involvement in the UKube-1 mission, though our C3D instrument, has had a positive effect on our research and technology programme within the Space Instrumentation Group at the Open University, as well as a positive effect on our technology partners in the project; XCAM Ltd and e2v Ltd. The project has helped the OU to build a new strand of instrument development within the group, raised awareness of the CubeSat platform as a potential vehicle to accelerate the development of scientific space instrumentation, and has provided early in-orbit-demonstration of technologies. The mission introduced us to new academic and industrial collaborators operating in the space sector and supported the career development of the young engineers and scientists working on the project.”

STFC’s RAL Space provided the Ground Station for the misison at Chilbolton Observatory in Hampshire UK, and UKube-1 operations were commanded from there. Mission Manager Dr Helen Walker said:

“It has been a very exciting time, made possible only with the great support from all the teams involved.”

Although the Agency-supported mission phase has ended, discussion is underway with AMSAT-UK about the possibility of taking over UKube-1 operations to continue its educational and outreach activities until the satellite orbit naturally degrades.

More information about UKube-1 can be found in the missions section of the UK Space Agency website


UKube-1 carries a set of AMSAT-UK FUNcube boards which provide an educational beacon for use by schools and a linear transponder for amateur radio communications.

UKube-1 nominal frequencies:
• 145.840 MHz Telemetry downlink
• 145.915 MHz FUNcube subsystem beacon
• 400 mW inverting SSB/CW linear transponder
– 435.080-435.060 MHz Uplink
– 145.930-145.950 MHz Downlink

The University of Southampton is developing its own CubeSat with a view to obtaining a free launch on the VEGA launch vehicle.

University of Southampton Small Satellite is a group of students, primarily from a physics background, who aim to get a fully functional satellite into space, possibly by the end of 2016. Over a number of years they have designed the structure, the power, attitude control and the onboard processing and work is continuing on the development and integration of these subsystems into a full operational system.

Wessex Scene recently published an article about the project which included an interview with Aleksander Lidtke who in 2014 gave a presentation about the CubeSat to the AMSAT-UK International Space Colloquium in Guildford.

Phil Crump M0DNY has released a video showing the first step of the Southampton University Spaceflight CubeSat Telecommand Board construction.
