The STELAR Project 2014

STELAR Logo SmallThe education and science charity STELAR has been active in promoting radiocommunications in schools and colleges for over 20 years, as part of curriculum enrichment and personal and professional development for teachers.

Through its specialist courses, it has achieved much notable success in establishing radio clubs in schools and inspiring young people to seek careers in science, electronics and industry. It has played a major role in space and satellite communications in schools.

In 2013 it provided opportunities for satellite experiment by offering SDR receivers to schools allowing them to participate in the current series of FUNCUBE satellite experiments.

Now in 2014 STELAR is offering a new challenge to educators both professional and Amateur. The phenomenal success of the Raspberry Pi computer has opened up new opportunities and stimulated demand for educational projects linking communications systems, via computers.

This year STELAR is seeking to support the very best of those ideas by making available grants to educational groups, with projects designed to stimulate experiments with radio linked computing.

Typically these might take the form of:
• Radio systems linked to but not exclusively, a Raspberry Pi, computer.
• A detailed Teachers guide to the use and benefits of FUNCUBE or similar satellite systems in schools,
• The creation of radio-science projects to aid teachers personal and professional development.

Educational groups can apply for funding to develop a project of their choice, by submitting ideas for consideration by June 30, 2014. Groups should set out their aims and giving as much detail as possible. Successful entries will be notified during the Autumn term.

Interested ? then make contact by visiting the STELAR website http://www.stelar.info/

KickSat launch postponed until Friday

KickSat Sprite CompetitionThe SpaceX CRS-3 Dragon launch of five CubeSats and 104 Sprite satellites has been postponed until Friday, April 18, 2014 at 1925 UT.

SpaceX were finally set to launch their Dragon spacecraft on its third Commercial Resupply Services mission to the ISS Monday, prior to a scrub being called over an hour ahead of lift-off. It is reported there was a helium leak on the first stage, the next launch opportunity is Friday.

The launch had been planned for December 2013 but has suffered a number of delays.

Configuration 4 was used:
* ARISS antenna 43
* Frequency 2395 MHz
* Symbol rate 2.0 MS/s

Ground stations G4KLB, F6DZP, IK1SLD and KI (Livorno) received the signals and streamed the video over the BATC server. The DATV signal was received for about 6 minutes.

Commander Wakata congratulated ARISS for this achievement and answered a series of questions, prepared in the manner of a school contact. He also proceeded to a microgravity experiment.

Congratulations to the Ham Video team for this outstanding performance.

Next step should be a video enhanced ARISS school contact. We will keep you informed on any progress.

The Ham Video transmitter has downlink frequencies of 2.369, 2.395, 2.422 and 2.437 GHz in a DVB-S type format (symbol rates of 1.3 Ms/s and 2.0 Ms/s). The two patch antennas, ARISS 41 and ARISS 43, are located on the nadir of the Columbus module. The Ham Video transmitter puts out approximately 10 W EIRP. The camera is a Canon XF-305.

Juno spacecraft QSL cards sent out

Juno Spacecraft QSL Card October 9, 2013

Juno spacecraft QSL card October 9, 2013

Juno QSL cards have been sent out to those radio amateurs who participated in the Juno Earth flyby experiment.

Amateur radio operators sent a very slow CW (1/25 WPM) to NASA’s Juno spacecraft during its Earth flyby on October 9, 2013.

Hams sent “HI” every 10 minutes as Juno approached Earth, and the message was clearly detected several times. The Juno team confirmed that more than 1400 radio hams participated, representing all seven continents.

ISS astronaut Koichi Wakata KC5ZTA will operate using the call sign OR4ISS. Ground stations F6DZP and IK1SLD will receive the signals and stream the video over the BATC server. The video is expected to be received during 5 minutes.

This will mark the end of the Blank Transmissions.

We thank the operators who filed reception reports of blank transmissions. Your  participation to the Ham Video testing campaign has been invaluable.

No decision has been taken yet on the future use of Ham Video. We will keep you informed on any progress.

KickSat Sprites – Radio Competition

KickSat Sprite Competition

On the KickSat updates page Zac Manchester KD2BHC has announced a competition to receive the first amateur radio signals from the KickSat CubeSat and the tiny Sprites satellites.

The KickSat CubeSat will carry 104 tiny Sprite satellites into a 325×315 km 51.5 degree inclination orbit. The launch carrying four other CubeSats, SporeSat, TSAT, PhoneSat-v2.5 and ALL-STAR/THEIA is planned for Friday, April 18, 2014 at 1925 UT and should be broadcast live on NASA TV and also streamed on Ustream.

Zac writes:

Our launch coming up in less than a week and, to keep things fun, I’d like to announce a little contest…

I’ll be offering prizes to the first several people who receive telemetry packets from KickSat as well as the first few who receive signals from the Sprites. The prizes will include souvenir Sprites and CRS-3 and ELaNa-V mission patches.

437 MHz Sprite

Now for the rules:
• In the case of KickSat telemetry, you have to send me the raw hex or ASCII packet data and I have to be able to successfully decode it.
• In the case of the Sprite signals, you have to send me a raw baseband recording and I have to be able to decode at least one Sprite signal from it.
• I’ll continue offering prizes until I run out of cool swag.
• I have the ultimate say on whether or not you win.

To get in on the fun, check out our wiki and join the KickSat mailing list. Let the games begin!

All the Sprites operate on a single frequency of 437.240 MHz and use Code Division Multiple Access (CDMA). The transmitter runs 10 mW output of Minimum Shift Keying (MSK) modulated binary data with each data bit modulated as a 511 bit Pseudo-Random Number (PRN) sequence. The ITU emission designator is 50K0G1D.

The KickSat CubeSat has downlinks on 437.505 MHz and 2401-2436.2 MHz.
