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.

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

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.

FUNcube-1 transponder to be active at weekends

Following the 48 hour test on April 5-6, the FUNcube-1 (AO-73) CubeSat team have concluded that the battery temperature does reduce slightly during full time transponder mode, but only by a degree C or so; it remains within specification. Hence it has been decided in future to switch the satellite into ‘forced eclipse mode’, i.e. full time transponder and low power beacon at weekends. The aim is to significantly increase the availability of the transponder to radio amateurs. This will continue until further notice.

The team plan to switch to full time transponder mode during the first suitable pass over the UK on Friday evenings, normally between 1930 and 2230 UT. If for some reason this is not possible, then the switch will be done on the first suitable pass on Saturday, normally between 0930 and 1200 UT. It is planned to switch the full time transponder mode off during a suitable pass on Sunday evenings, which normally occur between 1930 and 2230 UT. Again, if this is not possible the switch off will be made on Monday mornings, approx. 0930 to 1200 UT.

Do please note that this schedule is totally reliant on the availability of command stations, who will do their very best to ensure it is maintained. We will not normally announce successful full time transponder mode on/off commands, but if it proves not possible to make one of them, then we will make a note here and on the AMSAT Bulletin Board (AMSAT-BB).

So please do enjoy the transponder, and use it any time you hear it on. We are always pleased to hear of your activity, so either leave a comment below, or email g3wgm -at- amsat.org

Oscar 7 and 73 – The old and the new

SUWS WebSDR showing AO7 and 73 on April 3, 2014 at 1040 GMT

SUWS WebSDR showing AO7 and 73 on April 3, 2014 at 1040 GMT

A very good set of co-incident passes of both the AO-7 and FUNcube-1 AO-73 amateur radio satellites occurred over the UK on the morning of Thursday, April 3. The two satellites were launched 39 years apart, AO-7 on November 15, 1974 and FUNcube-1 AO-73 on November 21, 2013.

Simultaneous downlinks from both satellites could be clearly seen and heard on 2m, via the Southampton University Wireless Society (SUWS) online WebSDR at http://websdr.suws.org.uk/ which is available for use world-wide.

23cm_WebSDR_Antenna_up_mastNew Helical antennas designed by Martin Ehrenfried, G8JNJ, the installation of pre-amplifiers by Noel Matthews, G8GTZ, and a new PC build by Phil Crump, M0DNY have helped to dramatically improve the overall performance, especially on the 2m and 70cm Amateur bands.

The FUNcube-1 AO-73 BPSK telemetry beacon on 145.935 MHz is now up to 20dB above the receiver noise floor, and several stations using SSB, including Martin, G8JNJ, could be clearly heard on the 2m downlink via the SDR during last weekends transponder tests.

More improvements are in the pipeline, which we hope will help to further improve the receive sensitivity and reduce the level of interfering signals that can be observed on 2m.

Anybody can operate the SUWS WebSDR to receive signals from Satellites, and we really appreciate users leaving a message in the chatbox to let us know what they have heard.

Regards,
Martin – G8JNJ

Palle Haastrup OZ1HIA, President of Euroluna (OZ9LUNA), provides an update on the Romit-1 CubeSat which has ion motor propulsion.

Euroluna are a Danish amateur team participating in the $30 million Google Lunar X PRIZE contest to be the first privately funded team to land and drive a rover on the Moon.

Their first amateur radio satellite Romit1 is a 2U CubeSat that will transmit on 437.505 MHz using 1200 bps AX.25 packet radio. It will be fitted with an Ion Motor and if everything goes well it should, after a year, be able to raise the orbit from 310 km to 700 km.

It is planned to launch on an Interorbital Systems Neptune 30 rocket.

The team’s latest video update shows Romit-1 going into a vacuum chamber to test outgassing.
