AMSAT Field Day on the Satellites
It’s that time of year again; summer and Field Day! Each year the American
Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout,
practice
for emergencies, an informal contest and, most of all, FUN!”. The event
takes
place during a 24-hour period on the fourth weekend of June. For 2015 the
event takes place during a 27-hour period from 1800 UTC on Saturday June 27,
2015 through 2100 UTC on Sunday June 28, 2015. Those who set up prior to
1800
UTC on June 28 can operate only 24 hours. The Radio Amateur Satellite
Corporation (AMSAT) promotes its own version of Field Day for operation
via the
amateur satellites, held concurrently with the ARRL event.
If you are considering ONLY the FM voice satellite SaudiSat-Oscar-50 for
your
AMSAT Field Day focus … don’t … unless you are simply hoping to make one
contact for the ARRL rules bonus points. The congestion on FM LEO satellites
was so intense in prior years that we must continue to limit 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).

Brazilian CubeSat NanosatC-Br 1 Team Requests Reception Reports
Edson, PY2SDR requests fellow amateur satellite operators listen for a
downlink signal from NanosatC-Br 1, the first Brazilian cubesat. NanosatC-Br
1 was launched on a Dnepr rocket from Dombarovsky near Yasny in 2014.
The 1U CubeSat carries an ISIS U/V transceiver with 1200 bps FM AX.25 UHF
command uplink and a 9600 bps BPSK downlink on 145.865 MHz.
NanosatC-BR1, is experiencing battery issues for the last several months and
it now seldom emits a beacon in CW. For some time, Paulo PV8DX, was able to
detect a beacon signal when the satellite was over the Caribbean sea during
daylight. But now, no more signals have been detected.
Edson would like to request assistance from hams in the northern hemisphere
to see if NanosatC-BR1 is still transmitting any signals. Any help will be
much appreciated.
[ANS thanks Edson, PY2SDR for the above information]

FUNcube-1 / AO-73 Glitch and Commanded Reboot
On Sunday, June 21, there was an anomaly on FUNcube-1 that required the
reboot
of the satellite’s MCU (Microcontroller).
After a bus freeze, the databus watchdog did kick in as expected and
rebooted
the satellite. However, we did need to command the satellite back on to
automatic mode. When we did so on the 20:00 UTC pass, it came back up in
the
correct mode.
We envisage to switch back to autonomous mode either tonight or tomorrow
morning local time. FUNcube is still happy and healthy. This is the 4th
reboot
since launch, of which one was intentional. Thanks for your reports and
concerns.
On behalf of the whole team best 73s,

Kletskous Development News From the SA AMSAT Symposium
At the SA AMSAT Symposium pre-conference Engineering meeting held on Friday
evening on June 19, 2015, members of the SA AMSAT CubeSat team reached some
decisions about the development and launch of the South African Kletskous
amateur radio satellite. During the past few years, various options and
subsystems have been experimented with.
The team has now set the launch date of Kletskous at July 2017 with the
first flight model to be ready by February 2016 for testing after which
final integration will start. This requires that various module designs are
locked down and built by October 2015. It is planned to have all the modules
wired together in a breadboard configuration for testing the interoperation
of the various subunits by December 2015. Some modules are at a more
advanced stage than others, but in the next few months, the team expect to
catch up and meet the deadline for the first breadboard test.
Frik Wolff, ZS6FZ, the League's technical manager, has joined the team and
is working on solar panels and stabilization issues. Francois Oberholzer, an
honors student at Stellenbosch University, is working on improving the
weight/strength relationship of the space frame, a project that is part of
his thesis. Nico van Rensburg, ZS6QL, as programme manager and the person
responsible for documentation, will support the project manager, Hannes
Coetzee, ZS6BZP.
There are many opportunities for radio amateurs to join the engineering
team. If you have a particular expertise or passion to add value to the
KLETSKOUS project, please discuss your participation with Hannes Coetzee or
any of the team members and send your details to saamsat ＠ intekom.co,za.

North Texas Moon Day Event Annouced
A great opportunity to showcase Amateur Radio and especially Amateur Radio
in space to the general public will be held on Saturday, July 18th at the
Frontiers of Flight Museum in Dallas, TX. In commutation of the anniversary
of the Apollo 11 moon landing, the museum has celebrated "Moon Day" for the
last number of years as a STEM outreach specializing in astronomy, space
science and space flight past and future.
This year the Moon Day organizers decided to theme the day around the
International Space Station. They applied for and were granted an ARISS
scheduled contact to become part of the event. Keith Pugh, W5IU is serving
as ARISS mentor for the event and is working diligently on setting up all
the details of this "Telebridge" contact. The museum is sponsoring an "Ask
a question of an astronaut" contest with details at
http://www.flightmuseum.com/iss-expedition-crew-43-question/
General details can be found at
http://www.flightmuseum.com/moon-day-2015/
If you know young people interested in astronomy and space
science/exploration,
have them check out the links and see if they submit a question to be used
during the ARISS contact. Deadline for entry is June 30th.
In years past, several of us have participated in Moon Day activities by
manning an AMSAT table showing off Amateur Radio in space and even doing
some on-air contacts for and with interested participants.
Keith will be very busy all morning setting up and preparing for the ARISS
contact and has several individuals working with him on that. I have
volunteered to help staff an AMSAT display table but need additional
volunteers to assist with the table and also to be available to make Amateur
Satellite contacts and demonstrations as the sats allow. Please contact
Keith w5iu ＠ swbell.net or myself Tom Schuessler, n5hyp ＠ arrl.net to volunteer
to help at least part of the day or the whole 10A-5P duration and tell us
what you can "Bring to the table" as it were.
Help us to support the Museum's ARISS contact and also to put a bug in the
ears of many event goers about the fun and challenge of Amateur Radio
Satellites.

* Inventors hope to launch 'backyard satellites' to fill gap in Australian
space exploration
Stuart McAndrew is making history from a backyard shed in suburban Perth.
The IT worker is building a satellite capable of being launched into
space and
taking pictures of Earth.
Australia is the only OECD nation without a dedicated space agency, and Mr
McAndrew is one of a growing number of Australians turning to homemade space
exploration to fill the gap.
He has designed the satellite PocketQube, a Rubik's cube-sized box with
antennas, solar panels and electronics.
It is made from mostly off-the-shelf items, including aluminium from the
local
hardware shop, a tape measure and electronics bought over the internet.
Mr McAndrew believes it is the first of its kind in Australia. He has been
working on the project for two years.
"Australia has been lagging behind in recent times," he said. "We were
one of
the first countries to send an amateur satellite to space and then we
dropped
the ball.
"The PocketQube gives us an opportunity to set that straight and it (will)
hopefully inspire other people to continue on this path and build a bigger
space industry for Australia."
Radical change described as 'Space 2.0'
Commercial satellites weigh hundreds or even thousands of kilograms and cost
millions of dollars to launch.
In comparison, nano-satellites can be made for as little as $1,000 and weigh
between one and 10 kilograms.
Mr McAndrew's creation is even smaller, weighing less than 200 grams.
But how an earth do you get it into space?
It takes a lot of planning and a very expensive taxi ride on a much larger
space craft.
"The actual launch cost for a pocket cube is around $30,000," Mr
McAndrew said.
"That's a bit out of my reach so I'm looking to crowd source funding to help
me get my satellite into space."
About 80 nano-satellites were launched in 2013, while 132 went up in 2014.
It is estimated a further 500 will be in orbit by the end of this year.
The University of NSW is sending its own small satellites into space as part
of a global project.
Andrew Dempster, head of the university's Australian Centre for Space
Engineering Research, said the industry was going through a period of
"radical
change".
"Cubesats are creating this idea that people describe as Space 2.0," he
said.
"People like Stuart or universities like us can get relatively easy
access to
space and it means you can develop space capability without a space agency."
Mr Dempster said Australia's lack of a space program was concerning.
"For many years we've been receiving some of our data for free — we get our
our weather data from Japan; some of our remote sensing data we get from
Europe
and the US," he said.
"The problem is that's going to come to an end.
"Budgets are being restricted around the world; NASA's budget in
particular is
declining.
"So someone needs to be asking the question: what happens next?
"We're going to be left with our trousers down if we don't have a way of
providing the data we've become addicted to."
Inventors hope to 'unlock access to space'
Mr Dempster is hoping the rise of nano-satellites will encourage young
Australians to study science, technology, engineering and maths subjects and
put space on the agenda for a new generation.
"If you want to get young kids into science and so on, the things that do it
for them are dinosaurs and space," he said.
"The emergence of cubesats mean we can have our students working on
something
that will actually be launched into space, which attracts good quality
students
and very motivated people."
The expense and logistics of launching small satellites into space remains a
key problem.
An Australian organisation called the Delta-V Space Hub was formed last year
to solve it.
Tim Parsons is the head of Delta-V.
"There's no dedicated launcher for small spacecraft so typically we have to
piggyback off larger space launchers," he said.
"That means you have to deliver your spacecraft up to a year before the
launch
and hope it doesn't go brown on the pad.
"Those are the biggest limitations right now: the frequency of launch
opportunities and how much time you need to get everything prepared."
Delta-V is working with the NSW Government, universities and start-up
companies to help people develop ideas and get their inventions into space.
"Our first step is really just to fly an aircraft that other people can put
(their satellites) onto, so essentially a rideshare model," he said.
"By doing that first model we will essentially unlock access to space."
Call to lower cost for launch certificate
For Mr McAndrew, the backyard inventor, there are still a few barriers to
overcome. He must first test his satellite before obtaining a launch
certificate from the Australian Government, which costs $10,000.
The fee is reduced to just $100 for educational and scientific institutions.
Mr McAndrew wants the Commonwealth to ease those financial requirements in
recognition of the industry's potential.
He is still hopeful of securing a place for his satellite onboard an Italian
spacecraft set to launch late next year.
"Space has always been seen as this pinnacle of engineering and it's not
necessarily the case," he said.
"I can't wait for the day when I see the rocket launch into space with my
satellite on board."
