On Monday, May 4 at around 0830 UT it is intended to activate for one orbit the AMSAT-NL FUNcube-3 transponder on QB50p1 / EO-79.

TLEs are in the normal repositories, COSPAR 2014-033-R, Object# 40025. Real-time tracking at http://www.n2yo.com/satellite/?s=40025

We would like people to try the following frequencies if possible:
DOWNLINK: 145.960 MHz USB
UPLINK: Tune to match downlink +/- 435.065 MHz LSB
The transponder is linear inverting, nominally 30 kHz wide, and approximately 500 mW output.

If you find the transponder busy on those frequencies, feel free to move around and use the entire transponder passband.

The passband seems to have a “dip” in the middle which is bigger than expected, but we do welcome feedback about the usability. Also, please limit your uplink power, as it looks like this transponder is as sensitive as FUNcube-1. The spacecraft antenna is a monopole, so we would also be interested in signal fading reports.

The commissioning of the transponder done to date is very limited, three activations for 5, 10 and 8 minutes respectively. So your reports are greatly appreciated.

We do understand this is a very short notice, but hope that some of you will be able to participate. This was a take-it-or-leave-it opportunity offered by the ISIS engineers for our consideration, and we are again very grateful to ISIS and VKI for giving us this opportunity.

Please report contacts and signal reports to pa3weg@amsat.org

AMSAT-NL has announced that an initial series of tests of the FUNcube transponder payload aboard the QB50p1 CubeSat have been successfully completed.

QB50p1 is one of two QB50 precursor spacecraft that were launched from Yasny in Russia in June 2014.

The primary science payloads are still being extensively tested but it has now been possible to undertake a short test of the transponder payload as well. The transponder is intended as a long term secondary mission following the initial technology demonstration and de-risking phase.

After spending ten months in space, the transponder was commanded on for short periods during each of the three morning passes over Europe on Monday, April 27, 2015. A number of FUNcube team members in the Netherlands and in the UK were standing by to run through a predefined test plan.

The transponder has a similar performance to that of FUNcube-1 but the passband is nominally 5 kHz wider by design.

It is not yet known when this transponder may be available for regular usage but AMSAT-NL is delighted to be able to report that the hardware is functioning and is very grateful to the QB50 project, the Von Karman Institute and ISIS B.V. for their ongoing support.

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.

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.

FUNcube-1 Solar eclipse update

As expected, FUNcube-1 (AO-73) entered the shadow of the moon around 1000 UT on Friday, March 20, 2015.

Solar panel currents dropped to almost zeroThis is what happened to the solar panel currents, they dropped to almost zero.

This what we usually see from our Whole Orbit Data telemetry

This is what we usually see from our Whole Orbit Data telemetry. Normally the CubeSat is in the sun for 60 minutes and in eclipse for around 30 minutes…but not this morning!

The FUNcube team are pleased to announce that the Data Warehouse has received two million packets of telemetry data from ground stations around the world.

FUNcube-1 (AO-73) was launched on November 21, 2013 and since then radio amateurs and schools have been receiving the telemetry packets transmitted by the satellite and passing them to the AMSAT-UK Data Warehouse for analysis and storage.

There are normally several people uploading the same packet but for the 2 millionth it was an individual:

Carlos Eavis, G3VHF

The Data Warehouse statistics as of 09:53 UT on March 15, 2015 were:

Number of registered users: 1529
Number of active users (data received in last two weeks): 193
Number of active users since launch: 818

Number of packets transmitted by satellite since deployment: 8312304 (2.13 GB)
Number of packets uploaded by users before de-duplication: 8539662(2.19 GB)

Number of packets stored in warehouse: 2000000 (512 MB)

Number of packets recovered & stored – Time – Coverage
• Realtime 2M – 115 days – 25%
• HiRes 3.9M – 1085 minutes – 19%
• WOD 0.56M – 385.78 days – 80%

As always, many thanks for all those individuals and groups who are sending data to the warehouse.

Listen to FUNcube-1 during Solar Eclipse

Solar Eclipse - March 20, 2015

Solar Eclipse – March 20, 2015

There will be a total solar eclipse on March 20, 2015 which tracks across the North Atlantic and eventually covers a lot of the Arctic.

Path of Solar Eclipse  March 20 2015

Path of Solar Eclipse March 20, 2015

It would seem that this will affect most spacecraft that are in a polar orbit to some extent as, at that sort of time, they would expect to be in sunlight at the time and location.

On FUNcube-1 (AO-73) we have a good power budget which means that we should be able to maintain our normal autonomous operation schedule for the day but, of course, if the spacecraft does go fully into darkness it should switch autonomously to transponder and low power telemetry.

It will be interesting to see what actually happens and we hope that as many listeners as possible will upload the data they receive between 0740 and 1150 UT on that morning. Our Whole Orbit Data will show the solar currents, battery voltage and external temps clearly during this period so we should get a clear understanding of the effects on board.

If anyone has some software that can model the satellite’s track and the expected impact of the solar eclipse it would be great to hear about it!

On January 27, 2015 Abdel worked Jean-Marie Lenglet F2IL for his seventy third contact. He submitted his claim to Paul who checked it and sent the award certificate the following day.

Abdel was first licenced as M3IAK in 2003 and received his Intermediate call sign 2E0KAR in 2007 but it wasn’t until June 2013 that he was able to get on-the-air. He got his Full call sign M0NPT on March 11, 2014.

When Abdel first took an interest in satellites Lenny Brown 2E0LFK let him use his station and he had two contacts, with 9A3ST and R1AO, via the FM satellite SO-50.

Abdel then set up his own satellite station which comprises a Yaesu FT-847 with a 5 element horizontal polarised Yagi on 144 MHz, a 6 element vertically polarised Yagi on 430 MHz and a Yaesu G-5500 Azimuth-Elevation rotator. His first SSB contact via AO-73 (FUNcube-1) was with Manuel D. Ruiz Carrasco EA5TT on December 3, 2014.

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.
