On April 21, 2016, ESA’s Education Office set a challenge for the worldwide radio amateur community to start listening out for three new orbiting CubeSats. The results have now been released.

ESA’s Education Office published the transmission frequencies of the student-built satellites that were about to be launched as part of the Fly Your Satellite! Programme, and invited the radio amateur community to listen out for them.

The first three radio amateurs to send a recorded signal from AAUSAT4, e-st@r-II or OUFTI-1 would receive a prize from ESA’s Education Office. Hundreds of radio amateurs from around the world joined in the friendly competition.

The CubeSats started sending signals after their release from the Soyuz VS-14 rocket and the triggering of their automatic activation sequence. Participants from Russia, USA, Poland, France, Belgium, Netherlands, Brazil, Italy, Denmark, and more tuned their receivers and listened.

Thanks to skill and patience on the ground, the winners come from Russia, the United States of America, Germany, and the Netherlands.

Contact with the first CubeSat came at 00:53:51 UT on April 26, 2016, within an hour of its separation from the launcher. Dmitri Paschkow R4UAB, Russia, heard the signal from OUFTI-1 using two receiving stations, in Kemerovo and Ruzaevka. Upon hearing OUFTI-1, he communicated the news immediately. “I understand that the students are worried [to hear from their satellite] and decided to please them!” says Paschkow.

Just over an hour after the first signal from OUFTI-1 was recorded, the next CubeSat checked in.

AAUSAT-4 was heard over California, US, by Justin Foley KI6EPH of California Polytechnic State University. He had a personal interest in the mission because some of his colleagues had developed the P-POD deployer that was used to eject the CubeSats into orbit.

He was ready at the receiver from the moment of deployment but heard nothing on that first pass, probably because the activation sequence had not yet completed. The signal came through on the second pass, arriving at 02:02 UT.

“It was extremely exciting to see signals from the newly launched satellite, and witness the beginning of a space mission”, says Foley.

Then the wait began for e-st@r-II. At 05:40:58 UT, something dimly lit the screen of Mike Rupprecht DK3WN in Germany.  But something was not quite right. It certainly looked like a signal from the last remaining CubeSat, but why was the message so faint?  It galvanized the amateur radio community to look harder.

Jan van Gils PE0SAT had to wait until May 2 at 16:38:05 UT to receive a signal from e-st@r-II  that was strong enough to be decoded. Why e-st@r-II was only transmitting weak signals is under investigation, but the most important news is that all three CubeSats are functioning and transmitting, and their signals can be decoded.

A special mention goes to a young radio amateur who scored a personal best. Twelve year-old space enthusiast Matteo Micheletti from Belgium caught the OUFTI-1 signal with a portable log periodic antenna and a portable receiver. His triumph occurred on May 1, 2016 between 17:34 and 17:39 UT.

To mark their success, the radio amateur winners will each receive a Fly Your Satellite! Poster, a goodie bag and a scale 1:1 3D printed model of a CubeSat from ESA’s Education Office.

The ESA Education Office Fly Your Satellite! (FYS) programme is designed to train the next generation of aerospace professionals. Three chosen student teams have each developed 1U CubeSats carrying amateur radio payloads which are expected to launch at 2102 UT on Monday, April 25, 2016 on a Russian Soyuz-STA Fregat-M rocket from Kourou in South America into a 453 by 644 km 98.2 degree inclination orbit.

The satellites designed and built by the student teams, arrived in South America on Friday, March 25. Upon arrival, they were given a security escort from the airport to the Guiana Space Centre, near Kourou. The student teams arrived on March 28.

The satellites themselves are CubeSats. This class of small satellites have helped revolutionise access to space. Made of standard components, as the name suggests they come in modular dimensions of just 10x10x10cm in size.

On March 30 the students removed the so-called Remove Before Flight pins and successfully verified that the CubeSats were ready for launch. Afterwards, the lateral access ports of the P-POD were put back in place.  The next time the students will have contact with their respective CubeSats will be through the communication link after the satellites are deployed into orbit. The next activities consist in completing the application of a special thermal-optical tape on the outside of the P-POD, which will ensure the unpowered CubeSats are shielded from extreme thermal radiation during the launch phase. Finally, the planning for the next weeks will consist in integrating the P-POD with the rest of the launcher.

OUFTI-1 from the University of Liege, Belgium, will be the first satellite to carry a D-STAR Digital Voice transponder. The article ‘D-STAR digital amateur communications in space with OUFTI-1 CubeSat’ by Jonathan Pisane ON7JPD, Amandine Denis ON4EYA and Jacques Verly ON9CWD can be seen in the June 2013 Edition 202 of the AMSAT-UK publication OSCAR News.

e-st@r-II from the Polytechnic of Turin, Italy, will demonstrate an attitude control system using measurements of the Earth’s magnetic field; and AAUSAT4 from the University of Aalborg, Denmark, will operate an automated ocean vessel identification system.

Ham Video transmitter onboard ISS Columbus module

International Space Station ISS with shuttle Endeavour 2011-05-23

How a DATV transmitter on S-band is being added to the ARISS equipment onboard the International Space Station has been related in an announcement recently circulated and available at

http://www.ariss-eu.org/HamVideo.pdf

The ARISS Ham Video transmitter is presently onboard Columbus. The transmitter was delivered by Japanese cargo spacecraft HTV-4, which launched August 4 and docked 5 days later.

ESA astronaut Luca Parmitano KF5KDP / IR0ISS reported that the bags are stored in Columbus. There are two bags: one for the transmitter, the other for the power, camera and antenna cables.

Installation will be done by US astronaut Michael Hopkins KF5LJG who has been trained for the commissioning of the Ham Video equipment.The commissioning is planned later in the year, possibly end October when there are favourable passes over Italy. Indeed, the tests transmissions for the commissioning of the onboard equipment will be received by the ground station of the “Centro di Geodesia Spaziale” of the Italian Space Agency, located in Matera, Southern Italy.

We will report in due time on the commissioning procedure which will involve a series of tests to be performed during 3 or 4 ISS passes.

Possibly, the Ham Video transmitter will transmit continuously between the commissioning steps offering amateur ground stations the opportunity to test and tune their receiving equipment. The transmissions will be performed in automatic mode, without requiring crew time. The camera, which runs on a battery, will not be used and the ground stations will receive a black image.

Meanwhile, commissioning is being prepared steadily. The kick-off meeting took place November 2012 at ESTEC, the European Space Research and Technology Centre, located in Noordwijk the Netherlands.  Detailed procedures are examined and finalized during weekly ESA/ARISS teleconferences. A preliminary EST (Experiment Sequence Test) is planned August 28-29. The test will involve the ARISS ground station IK1SLD, located in Casale Monferrato in Northern Italy.

IK1SLD, which is an ARISS telebridge station often used for educational ARISS school contacts on VHF, has been upgraded for S-band reception. Ham Video manufacturer Kayser Italia has delivered a 1.2 meter dish, a down converter and precision tracking motors, which are part of the ESA funded equipment. For the EST, the station will receive a DATV signal from a local low power S-band test transmitter. The decoded signal will be webstreamed to the BATC server. The British Amateur Television Club offers ARISS free access to their server. ESA examiners will connect to the BATC server and evaluate the reception. Test transmissions at IK1SLD will cover the different frequencies and symbol rates available on the Ham Video transmitter.

Web streaming will take advantage of the special software developed by Jean Pierre Courjaud, F6DZP. References are available in the HamVideo.pdf.

When the Ham Video transmitter will become operational, it will be used for ARISS educational school contacts. Video will be for downlink only. Uplink will be VHF FM audio. The Ericsson transceiver onboard Columbus will be used for reception onboard. This cross band and double mode operation is called Ham TV. Ham Video is the name of the DATV transmitter.
