LituanicaSAT-1

Dear amateur satellite radio operators,

A courtesy notice that LituanicaSAT-1 FM transponder test is in progress. Today we performed initial operational test over Lithuania successfully. Downlink frequency was noted to have shifted to 435.1755 MHz. More tests are needed to verify that and determine exact uplink frequency shift but 145.950 MHz should work.

Please remember to use CTCSS PL 67 Hz sub-tone. If no problems will be encountered the operational tests for 23rd of April are planned to resume on 12:45 UTC and finish on 16:00 UTC. Just after activation you should here callsign in Morse and short salutation message from Lithuanian president. This identification message is transmitted every 5 min if there is no radio activity as well.

Your reports are more than welcome. Please submit your reports to ly5n@qrz.lt (please provide some supporting data like frequencies, max elevation of the pass, signal to noise ratio, etc.). Also please feel free to share this information through any media channels.

Best Regards,
LituanicaSAT-1 team

Monitoring AO-73 with Minimalist Equipment

In this video Clint Bradford K6LCS demonstrates that a simple antenna is all you need to get a signal the FUNcube-1 (AO-73) telemetry beacon.

Clint writes: AO-73 just passed to the West over Southern California. With just a tape measure beam and a Yaesu FT-60R, it was received. AO-73 is transmitting at about 30 mW on 145.935 MHz today in the sun, and was never closer than about 450 miles.

Watch Monitoring AO-73 – Minimalist Equipment

In the video Clint was also using an  iPod touch, running the satellite tracking App PocketSat3 from http://www.pocketsat.com/

The AO-73 beacon uses BPSK modulation. To demodulate and decode the telemetry data you need a SSB receiver (FT-817, RTL-SDR, FUNcube Dongle, etc)  and the free Dashboard software. Clint made the video at the weekend when the beacon was in low power mode running just 30 mW. During the daylight hours on Monday-Friday the beacon runs 300 mW output so would be an even stronger signal.

Lift-off of SpaceX CRS-3 with five CubeSats and 104 Sprite satellites

Five CubeSats including KicksSat which carries 104 Sprite satellites on 437 MHz were successfully launched by the SpaceX CRS-3 mission on Friday, April 18 at 19:25:22 UT.

Zac Manchester KD2BHC and the SpaceX Falcon-9 CRS-3

Zac Manchester KD2BHC and the SpaceX Falcon-9 CRS-3

Zac Manchester KD2BHC says:

After a beautiful launch KickSat was deployed in low Earth orbit. We at Cornell and several amateur radio operators around the world have made contact with the spacecraft and it is alive and well. I can’t thank all of you enough for your tremendous support over the past two years. Thank you for believing in KickSat!

This is the culmination of a lot of hard work and is a huge milestone, but we’re not done yet. In 16 days the Sprites will deploy from KickSat. We need as many people as possible listening in, so if you’re interested, please check out the wiki and our mailing list for more information. As always, don’t hesitate to contact me with questions.

The CubeSats KickSat, SporeSat, TSAT, PhoneSat-v2.5 and ALL-STAR/THEIA were deployed into a 325×315 km 51.5 degree inclination orbit.

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.

Zac writes: 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!

CRS-3 CubeSat frequency chart by Mike Rupprecht DK3WN

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.

The latest issue of the free BAA-RAG radio astronomy publication RAGazine is now available for download.

The British Astronomical Association Radio Astronomy Group (BAA-RAG) Coordinator Paul Hyde G4CSD writes:

1. RAG 2014
A reminder that BAA RAG is holding this year’s General Meeting at the National Space Centre, Leicester on Saturday, May 17, starting at 10:30.  We have two keynote speakers in Prof Paul Cannon (on solar superstorms) and Dr Klaas Wiersema (on Gamma ray Bursts) plus seven supporting talks to create a packed day on radio astronomy and geophysics.  Tickets are still available at £15 (£12 for BAA members) which includes free admission to the NSC and free parking.  Further information on the event, including details of the presentations, can be found on the BAA RAG website at www.britastro.org/radio/.  Bookings can be made by post, phone, fax or email using the Booking Form downloadable from the same website.

2. RAGazine
The 3rd edition of the RAG quarterly newsletter is now available for download from the BAA RAG website (see above).  This edition contains Karl Jansky’s 1932 paper identifying additional radio noise to that originating from thunderstorms, a review of the recent book on the life and times of Sir Bernard Lovell, and a description of the Siberian Solar Radio Telescope, along with articles on meteor scatter, magnetometry and VLF activity, plus Tony Abbey’s Technology Watch column.

We are always on the look-out for material for RAGazine.  The publication is an informal newsletter for sharing information and experiences in amateur radio astronomy and geophysics and we do depend upon input from those reading it.  We would like to move to publishing every other month, rather than quarterly, provided we can get a steady supply of material.  The Editor (Dave James) is keen to feature members’ home observatories, outreach activities, co-operative ventures and the like. We would also like to find one or two more contributing editors or correspondents for specific areas who can provide regular material on particular areas they feel would be of interest to readers.

If you can offer anything here please contact the Editor – dave<at>greenover.net.

3. HLOG project
The Hydrogen Line Observing Group was set up by Gordon Dennis and Brain Coleman to make use of Brian’s 3.7m diameter dish at Redenham Observatory for measuring Hydrogen Line emissions from the Galactic Plane.  Despite the high winds earlier in the year which twice damaged the azimuth gear box, observations have been largely completed from Galactic Longitude 20 to 94 degrees with some observations at 108, 110 and 180 degrees. The team is now looking for additional volunteers to extend the survey to at least 120 degrees longitude and maybe to 180 and beyond, plus an increased range of latitudes, in some cases as far as ± 14 degrees to capture all the “structure” detectable with the instrument.  Help is also needed to process the resultant data and re-check observations.

The project provides you with an opportunity to do some serious observing with a decent size dish.  All you need to participate is internet access and the time to set up and monitor individual scans.  As an observer you have access to the data collected by the whole Group for your own analysis work.

Those wishing to join the team should contact Gordon Dennis at gordon.dennis<at>koalapub.co.uk

Best wishes

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/contact
