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.

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!

*FOX-1 upp 2014

Ersättaren till den populära FM satelliten AO-51 har ju redan ordnat
sponsrad uppskjutning, så nu kan vi se fram mot en fin satellit för portabla
satellitkontakter.

AMSAT Fox-1 Launch Date Announced

NASA announced on May 13, 2013 that AMSAT’s Fox-1 spacecraft has been
assigned for launch in 2014 on the ELaNa XII mission. The expected orbit is 470 x 780
km at 64 degrees inclination. This orbit has a lifetime of about 11 years.

AMSAT Vice President Engineering, Tony Monteiro, AA2TX, reported that the
software development team successfully brought up the Fox-1 system software
on the Internal Housekeeping Unit (IHU). The IHU is the brains of the Fox-1
satellite and it has a 32-bit, STM32L microprocessor. The operating IHU card was
shown in the AMSAT Engineering booth at the Dayton Hamvention.

The Fox-1 Engineering Team will deliver the satellite for integration with
the launch vehicle during May, 2014 with the launch scheduled for November,
2014. Tony commented, “While this is later than we had hoped, it is well within
the normal variance of ELaNa launch dates and the extra time will be most
welcome for additional satellite testing. This is very exciting news and really puts the
focus on finishing the satellite and ground station software development.”

President Barry Baines says, “AMSAT’s focus on STEM education and development of
a cubesat platform capable of flying a science mission with a reliable communications link resulted in the selection of Fox-1 in the third round
and RadFxSat (Fox-1B) in the fourth round of NASA’s Cubesat Launch Initiative.”

All Fox cubesats are designed to host advanced science payloads to support
future science missions that help us to continue qualify for NASA ELaNa
(free) launches. The Phase 1 Fox satellites are 1-Unit CubeSats. They each include
an analog FM repeater that will allow simple ground stations using an HT and an
“arrow” type antenna to make contacts using the satellite. This was the mode
made so popular by AO-51. The Phase 1 CubeSats also have the capability of
operating in a high-speed digital mode for data communications. Phase 2 Fox
satellites will include software-defined-transponders (SDX) like the one
tested on ARISSat-1. These will be able to operate in a wide variety of analog and
digital communications modes including linear transponders. Since this
requires more power for reliable operation, these will probably all be 3-Unit
CubeSats.

*ISS kommer med videolänk på 2,4 GHz

Frequencies announced for HamTV from the International Space Station

Frequencies have been announced for the new Ham Radio Digital TV transmitter
that will send video from the ISS in the amateur radio 2400 MHz band.

The main mission of HamTV is to perform school contacts between the
astronauts onboard ISS and the scholarship, not only by voice, but also by
unidirectional video from the ISS to the ground within the ARISS program.

In addition to the existing VHF radio amateur station, ISS will host a
S-Band video transmitting station. This new equipment can broadcast images from the ISS
during the school contacts or other pre-recorded video images up to 24 hours
a day to allow ground stations tuning.

It is planned to transmit DVB-S signals on 2.4GHz at either 1.3Msps or
2.3Msps with 10 watts of RF from the ISS Columbus module. The IARU Amateur Satellite Frequency Coordination Panel have announced
frequencies of 2422.0 MHz and 2437.0 MHz.

HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the
name of the complete system, comprising DATV downlink and VHF voice uplink.
Kaiser Italia SRL was the prime-contractor for the design and development of the flight
and ground segment http://www.kayser.it/index.php/exploration-2/ham-tv

Italian astronaut Luca Parmitano KF5KDP is planned to launch from Baikonur
in Kazhakstan to the ISS on May 28 (see High School Student’s RocketHub
Project). It is understood that the HamTV equipment will be carried to the ISS on the
Japanese HTV-4 spacecraft currently planned for a launch on August 4.
