Christer Fuglesangs radiokontakt från ISS

Den 17 december 2006 lyckades Thunmanskolan genomföra en amatörradiokontakt med Christer Fuglesang ombord på ISS via en s.k. telebridge. Sätraskolan, i södra Stockholm, blev den enda skolan i Skandinavien som fick en amatörradiokontakt med Christer när han åter igen besökte Internationella Rymdstationen i september 2009. AMSAT-SM dåvarande ordförande Eskil SM5SRR hade som projektledare en avgörande roll i genomförande av kontakten.

Planering för videosändningar från ISS

Här kommer lite information om planerade videosändningar från ISS. Som vi kan läsa är de planerade att ske på S-bandet:

ISS_hela_stationen

ARISS-Europe Chairman Gaston Bertels, ON4WF has drafted an overview of a new “Ham Video” DATV downlink system on S-Band being developed for placement on the International Space Station later this year. The equipment is being developed by Kayser Italia under contract with the European Space Agency using a Canon XF-305 camera provided by NASA. The equipment is currently slated for deployment to the ISS on Japan Space Agency’s HTV-4 in August 2013. HTV is Japan’s H-II Transfer Vehicle for resupplying the International Space Station.

Gaston’s paper provides an overview of both the equipment that is being placed on the ISS as well as discusses ground station requirements.  The ESA contract calls for Kayser Italia to provide five ground stations for placement in Europe that will be “chained” to provide overlapping video reception coverage, with the British Amateur Television Club (BATC) serving as a central server site for receiving video from these ground stations and making it freely available to others via the internet.

It is hoped that amateurs will support other ground station “chains” in other countries as multiple stations are needed to provide up to 15 minutes of video in support of school contacts. Gaston’s paper with block diagram and photographs of key components will be available soon on the AMSAT website (www.amsat.org).

AMSAT Field Day 2013

AMSAT-NA anordnar varje år en “Field day”. Läs mer om detta trevliga event!

Every year AMSAT promotes a satellite version of Field Day during
the ARRL annual operating event which is held on the 4^th weekend in
June. This year Field Day will take place from 1800 UTC on Saturday
June 22, 2013 through 2100 UTC on Sunday June 23, 2013.

SaudiSat-Oscar-50 will be the only operational FM transponder
satellite this year. If you are considering only FM voice operating
for your AMSAT Field Day focus the single uplink/downlink channel
will be extremely challenging. As in prior years, this intense
congestion on FM LEO satellites drives the limitation in the rules
allowing their use to one-QSO-per-FM-satellite. This includes the
International Space Station. You will be allowed one QSO if the ISS
is operating Voice. You will also be allowed one digital QSO with the
ISS or any other digital, non-store-and-forward, packet satellite (if
operational).

If you have worked the satellites on Field Day in recent years, you
may have noticed a lot of good contacts can be made on the linear
transponder satellites including VO-52, FO-29, and AO-7. During Field
Day the transponders come alive like 20 meters on a weekend. The
transponders on these satellites will support multiple simultaneous
SSB or CW contacts.

The AMSAT Field Day 2013 event is open to all Amateur Radio
operators. Amateurs are to use the exchange as specified in ARRL
rules for Field Day. The AMSAT competition is to encourage the use of
all amateur satellites, both analog and digital.

For the complete listing of the AMSAT Field Day Rules please refer
to the documents posted on-line at:

Nytt Fox-2 team

Från ANS-167 kommer följande:

Fox-2 MPPT Team Selected In TI Design Contest

AMSAT sponsored a senior design project at the Rochester Institute
of Technology this academic year.
The students included senior EE majors:
Bryce Salmi KB1LQC
Brent Salmi KB1LQD
Ian MacKenzie KB3OCF
and Dan Corriero.

The project was to develop an MPPT circuit that could be used on a
future Fox-2 (3U) CubeSat. The students completed a working prototype
which was on display in our engineering booth at Dayton last month.

With my agreement and encouragement, the students entered this
project into Texas Instruments’ 2013 Analog Design Contest for
university students.
See: http://tinyurl.com/mf6nzhr

I am happy to pass along the great news that the AMSAT MPPT project
was selected as one of the top 10 semi-finalists and the students
were invited on an all-expenses paid trip to TI’s contest summit to
be held July 21-23 in Dallas where the final winners will be
announced.

Congratulations to the Fox-2 MPPT team!
