HAMSAT VO-52 Falls Silent



The amateur radio satellite HAMSAT VO-52 ceased operating on February 28, neither it’s beacon or 435/145 MHz SSB/CW linear transponder have been heard since.

Ib Christoffersen OZ1MY reported that he heard and briefly used the transponder on the pass with Acquisition of Signal (AOS)  in Copenhagen at 0826 UT on February 28. On the next pass with AOS at 1003 UT it was not on.

Mani VU2WMY provides this update:

Dear HAMSAT VO-52 users,

With regrets, we confirm the non-availability of the transponder on HAMSAT VO-52 since 28th February 2012. This is the first ever interruption in the services of HAMSAT since 5th May 2005.

The timely feed back from John K8YSE, Domenico I8CVS, Eugenio IZ8JHD, Jan PE0SAT and Nitin VU3TYG were highly appreciated and acknowledged by the ISRO’s HAMSAT Mission Management Board.

I’m herewith enclosing the mail received from Mr. T.Parimalarangan, Operations Director-HAMSAT VO-52 regarding the ‘Temporary Non-availability’ of VO-52 transponder and beacon.
Mr. Subramani VU2WMY:

Thanks for obtaining the user feedback. You may please post the following message in the Users website. If possible, try to find out who has last operated HAMSAT payload transponder on 28th and at what time

“HAMSAT Transponder services not available temporarily due to operational reasons. Inconvenience regretted”

With Best Regards,

Ph:  080 – 2202 9011 (O)

AMSAT-UK Net Recorded via 20 km WiFi Link

Simon Brown HB9DRV in Switzerland has made available a recording of Sunday’s AMSAT-UK 80m net that he made using a remote receiver in Poole, Dorset. What is remarkable about this recording is that a 20 km long experimental 2.4 GHz WiFi link was used at the Dorset end.

The AMSAT-UK net is held every Sunday morning at 10am local time on a nominal frequency of 3.780 MHz. Due to interference the net may move either side of that frequency so tune around. Newcomers are most welcome to call-in.

Listen to the AMSAT-UK Net recorded Sunday, February 26, 2012. Due to the experimental nature of the 20 km WiFi link there are a few breaks in the recording.

NASA has selected 33 small satellites to fly as auxiliary payloads aboard rockets planned to launch in 2013 and 2014. The proposed CubeSats come from universities across the country, the Radio Amateur Satellite Corporation, NASA field centers and Department of Defense organizations.

CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites are approximately 10 cm long, have a volume of about one litre and weigh less than 1.3 kg.

The selections are from the third round of the CubeSat Launch Initiative. After launch, the satellites will conduct technology demonstrations, educational research or science missions. The selected spacecraft are eligible for flight after final negotiations and an opportunity for flight becomes available. The satellites come from the following organizations:

— Air Force Institute of Technology, Wright-Patterson AFB, Ohio
— Air Force Research Lab, Wright-Patterson AFB
— California Polytechnic State University, San Luis Obispo
— Cornell University, Ithaca, N.Y.
— Massachusetts Institute of Technology, Cambridge
— Montana State University, Bozeman
— Naval Postgraduate School, Monterey, Calif. (2 CubeSats)
— NASA’s Ames Research Center, Moffett Field, Calif.
— NASA’s Goddard Space Flight Center, Greenbelt, Md.
— NASA’s Jet Propulsion Laboratory, in partnership with the California Institute of Technology, Pasadena (2 CubeSats)
— NASA’s Kennedy Space Center, Cape Canaveral, Fla.
The Radio Amateur Satellite Corporation, Silver Spring, Md.
— Saint Louis University, St. Louis
— Salish Kootenai College, Pablo, Mont.
— Space and Missile Defense Command, Huntsville, Ala. (2 CubeSats)
— Taylor University, Upland, Ind.
— University of Alabama, Huntsville
— University of California, Berkeley
— University of Colorado, Boulder (2 CubeSats)
— University of Hawaii, Manoa (3 CubeSats)
— University of Illinois, Urbana (2 CubeSats)
— University of Michigan, Ann Arbor
— University of North Dakota, Grand Forks, N.D.
— University of Texas, Austin
— US Air Force Academy, Colorado Springs, Colo.
— Virginia Tech University, Blacksburg

Thirty-two CubeSat missions have been selected for launch in the previous two rounds of the CubeSat Launch Initiative. Eight CubeSat missions have been launched (including five selected via the CubeSat Launch Initiative) to date via the agency’s Launch Services Program Educational Launch of Nanosatellite, or ELaNa, program.

ITF-1 CubeSat – Imagine The Future

University of Tsukuba ITF-1 (YUI) CubeSat

University of Tsukuba ITF-1 (YUI) CubeSat

Students at the University of Tsukuba are working on the ITF-1 (YUI) CubeSat project that is planned to be launched on a H-IIA rocket in the fiscal year 2013. The orbit will be 400 by 350km with an inclination of 65 degrees.

The formal name ITF-1 comes from the initial letter of the university slogan “Imagine The Future”.  The satellite also has a popular name YUI which means “bond” in Japanese, it came from the project’s concept‚ “Creating the Worldwide Human Community”.

The 435MHz satellite beacon will send telemetry by a Morse Code audio tone on an FM transmitter running 300 milliwats output. It should be possible to receive it using simple equipment such as a handheld transceiver or scanner. Telemetry information will be first compressed into binary data  and then cut into 5 bits and converted into 10 – 15 Morse codes.

Ayano Okamura ITF-1 Project Manager

Reception reports will be acknowledged with a certificate and the telemetry will be made available on the web.

FUNcube at Association for Science Education Conference

Graham Shirville G3VZV on AMSAT-UK Stand at ASE

Graham Shirville G3VZV on the AMSAT-UK Stand

The 3 day Association for Science Education Conference opened in Liverpool on Thursday, January 5.

AMSAT-UK have a stand at the conference to show the potential of the FUNcube satellite as a teaching tool.

The FUNcube project aims to boost young people’s interest in Science, Technology, Engineering and Mathematics (STEM).

When FUNcube-1 is launched this Autumn school students will be able to receive the satellite data stream which contains telemetry — things like battery voltages and solar panel currents — and from this they’ll be able to deduce things like the spin rate of the satellite, and what happens to temperatures when it goes into or out of eclipse.

Additionally students will be able to send, via a moderator, ‘Fitter’ (as in ‘FUNcube Twitter’) messages of 200 characters to the satellite.  FUNcube-1 will then transmit them down to Earth on its 1200 bps BPSK beacon.

The event takes place at the University of Liverpool from January 5-7. Admission to the exhibition is free, details at http://www.ase.org.uk/
