Space.com reports Planet Labs is launching 28 Dove 3U-CubeSats early 2014,
presumably like Dove-1/2 using 2400 MHz.
http://www.space.com/22622-planet-labs-dove-satellite-photos.html
I'd heard a similar number of CubeSats were going to be deployed from the
International Space Station in 2014 by NanoRacks.
Can anyone confirm the Dove CubeSats are being deployed from the ISS ?

I think this 2-part 4 minute video is very relevant here:
http://www.youtube.com/watch?v=51fKeeHSxTg
*Building a SpaceCraft*
Although less bureaucratic companies/organizations will widdle down this
process considerably it still holds true. Once that rocket launches there
is no turning back, Year's of peoples lives goes into making the several
minutes of reaching orbit actually work and not kill your spacecraft. Each
part on a spacecraft needs to be designed correctly, tested to operate
correctly, tested to operate in all expected conditions (vibrations,
temperature, radiation, etc...) without any physical maintenance.
Funcube vibration testing: http://vimeo.com/26954073
Getting to orbit is a very difficult process, in-fact the first seconds of
the launch is very very violent and has a high potential to destroy
satellites on-board. Vibrations due to the ground reflections will
potentially rip components right off the PCB, unscrew bolts/connectors...
I've seen this happen in testing and when it does it's time to go back to
the drawing board and re-layout your board or parts to dampen/strengthen
it. All electronics need to survive the lack of air convection taking heat
away from hot things (think amplifiers...) as well as survive incredibly
cold temperatures, temperatures in space do not change slowly, they will
crack PCB's, components, etc... All spacecraft need to be qualified for
flight to ensure the $100,000's (if not hundreds of millions) of dollars
and years of people's efforts are not doomed from the beginning, many
launch providers require these specifications to be met even to fly on
board their rockets.
*Getting to Orbit - And Surviving*
Getting to HEO is also another challenge since we must travel through the
van-allen belts, and survive the long-term exposure of higher radiation.
That nice micro-controller that works well on earth or in LEO now has bit's
flip, gates short, and other analog components dies a slow but steady death
as well in this radiation environment. All of this needs to be ensured to
work.
For the launch itself, there are many more players in the market and many
(schools...) that are willing to shell out several million easy. If you're
on-board a HEO launch your likely going to be going under very strict
guidelines and you must prove that you won't hurt the main satellite
through rigorous documentation and testing. I'm not say that this is
unfeasible as we've done this in the past but getting a LEO bird up is
considerably easier and cheaper as compared to a HEO.
I also want to say that the cubesat standard is a wonderful thing, cubesat
electronics are getting better, more reliable, and are increasing their
functional density which means we can do more with less space/weight! The
modular systems of cubesats also pave the way for *faster builds and
cheaper R&D in the long run!* Standardizing radio/power/control systems
into modular boards means we can optimize, upgrade, and reused designs
quickly and focus on the bigger better things in years to come. Building a
solid LEO cubesat base is very important for this very reason as we can
learn to use the platform and avoid re-designing the wheel in years to
come. Fox-1 is that stepping stone for us and Fox-2 will provide the
continuing efforts to make larger, better, and more capable spacecraft!
Each Fox satellite specifically improves on the previous design and when we
get a solid and reliable system that can scale to large cubesats (6U) we
will have a reliable bird in the sky with incredible functionality.
*Utilizing Our SAT's - SDR's*
I think it's also a good time to think about utilizing our LEO birds for
not just voice communications but for data (both communication and
sensors/cameras) which current technology makes much easier. With
additional help to the effort I don't see why a simple and cheap ground
station set-up can't be developed and sold that directly increases the
ability for people to use our satellites. Think FUNcube(
http://www.funcubedongle.com/), what better way to increase access and
abilities than a cheap and somewhat dedicated ground system? If we're
always limited to 1200 baud through an HT or multi-band radio we'll never
explore other technologies. SDR's are cheap nowadays and offer the ability
to directly downlink voice and data flexibly.
Anyways, that's my 2 cents! I welcome all of you to help volunteer even if
you've never been involved in the aerospace industry! From managing, to
public appearance, to engineering AMSAT is always looking for help and it's
a great way to give back to the hobby that all of us love. This hobby was a
large factor in my career choice and AMSAT satellites were a big draw for
me. *Most of my other college peers and even young co-workers love what
AMSAT stands for* and how we do it! The more excited and cooperative
everyone is the more people will get on-board. I know ton's of people
(technical and not) that are incredibly interested in what AMSAT is doing
and just need a push to jump in.
Thanks,
Brent, KB1LQD

Hi,
I think it takes about 2500m/s delta V to get from from LEO to a GTO.
How feasible is it to use some type of an electric thruster (high
specific impulse but low net thrust - eg a hall effect thruster or
similar device) to slowly crawl up to GTO from LEO?
I imagine that such a bird would charge it's batteries from solar power
for most of an orbit, and would power the thruster from battery power
during each perigee to slowly raise the apogee altitude. This would
allow the use of a thruster with an peak electrical demand that is
higher than the peak power generating capacity of the PV cells.

FUNcube-1 Launch Date Announced
AMSAT-UK and AMSAT-NL are delighted to be able to announce that they
have been
advised that the launch date for FUNcube-1 is now expected to be
November 21,
2013. This date is still subject to final approval by the authorities.
The FUNcube project started back in 2009 so it is a great relief that we now
have a confirmed date for lift off.
FUNcube-1 will lift off from the Yasny launch base located in the Orenburg
Region, Russia on a Dnepr Launch Vehicle that will insert multiple
satellites
into a 600 km sun-synchronous orbit.
FUNcube-1 is a 1U CubeSat that will provide a signal directly from a
satellite
in space to the classroom, and can easily be received by schools and
colleges.
The target audience is students at both primary and secondary levels. The
information will be displayed in an attractive format and provide
stimulation
and encouragement for students to become interested in all STEM (Science
Technology Engineering & Maths) subjects in an unique way. In addition the
spacecraft is also carrying a 435/145 MHz transponder for radio amateurs
to use
for communication using SSB or CW.
The spacecraft itself has now been completed and the last external panel was
finally screwed and glued in place on Friday, August 30 at the facilities of
ISIS BV in Delft. FUNcube-1 will be subjected to some final testing and
battery
charging on Tuesday when it will also be set into its pre-launch
configuration.
It will then be placed into its ISIPOD on Wednesday ready for transport
to the
launch site.
Communication subsystem:
? 400 mW Inverting linear transponder for SSB and CW
- Uplink 435.150 ? 435.130 MHz
- Downlink 145.950 ? 145.970 MHz
? 400 mW BPSK Telemetry 145.935 MHz
More information about how to receive the signals from FUNcube-1 will be
made
available over the forthcoming weeks at the www.funcube.org.uk website.

A Ham Radio AX.25 Open Source Soundcard Modem
AX.25 packet radio is currently the most popular data protocol for use in
CubeSats.
Radio amateur Alejandro Santos LU4EXT is developing extmodem, an open source
APRS compatible AX.25 packet radio modem.
It is currently capable of both sending and receive packets. The main
feature
of the software is that it is currently running three different
demodulators in
parallel, increasing the quality of reception. The first modem is Thomas
Sailer
HB9JNX / AE4WA?s multimon, the other two are described by Sivan Toledo
4X6IZ in
an article in the July/August 2012 issue of QEX.

Ham Radio Satellites at Tokyo Ham Fair
The JARL Ham Fair 2013 was held at Tokyo Big Sight, Ariake, Tokyo on
August 24-
25. JAMSAT and several amateur radio satellite projects were represented.
The University of Tsukuba CubeSat ITF-1 YUI ?Binding? support project was
there. 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 or binding in Japanese, it came from the project?s concept?
?Creating the Worldwide Human Community?.
The ITF-1 satellite beacon on 437.525 MHz 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.
According to the ITF-1 website the ?Binding? support project is organized by
the student volunteers to support the construction of a consolidated network
and expand public relation activities with the aim of encouraging many
reception reports when the satellite is launched. ITF-1 will fly with the
primary payload the Global Precipitation Measurement Dual-Frequency
Precipitation Radar GPM-DPR satellite in 2014.
The ARTSAT stand featured the Invader CubeSat which is being developed by
students at Tama Art University. The IARU has coordinated 437.325 MHz and
437.200 MHz for Invader which aims to have a camera for Earth imaging and a
Digi-Talker, to transmit voice data using FM. Invader will be on the same
launch as ITF-1.
Also at the fair was the SPROUT project. This nano-satellite, built by
students from Nihon University, is 20 x 20 x 22 cm with a mass of 6.7 kg. It
plans to launch with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic
Aperture Radar (SAR) satellite ALOS-2 in December, 2013.
SPROUT will have a digi-talker and will transmit, using Slow Scan TV (SSTV)
and FM packet, pictures of the Earth taken by an on-board camera. It is
believed that radio amateurs will be able to make use of the digipeater and
possibly even command when pictures are taken.

ARISS is an international educational outreach program partnering the
participating space agencies, NASA, Russian Space Agency, ESA, CNES,
JAXA, and
CSA, with the AMSAT and IARU organizations from participating countries.
ARISS offers an opportunity for students to experience the excitement of
Amateur Radio by talking directly with crewmembers on-board the
International
Space Station. Teachers, parents and communities see, first hand, how
Amateur
Radio and crewmembers on ISS can energize youngsters' interest in science,
technology, and learning. Further information on the ARISS program is
available
on the website http://www.ariss.org/ (graciously hosted by the Radio
Amateurs
of Canada).

Satelite Shorts From All Over
Work All Ron, N8RO
Look for Ron, N8RO who is enjoying a long road trip that
began on Friday Aug 30th. Ron is heading north through OK,
KS, NE, SD, ND and SK. He will then head east on the Trans
Canadian Highway to MB, ON, QC, NB and NS. From NS he will
go to ME and MA and then work his way home to TX. While the
trip is primarily a vacation, he will attempt to make satel-
lite contacts, hopefully two a day, one morning and one
evening, on SO-50 and FO-29 along the way. (Ron, N8RO on

Russian Spacewalk Installs Commercial Camera Mounts
UrtheCast Corp. is pleased to announce that Roscosmos has successfully
installed the Bi-axial Pointing Platform (BPP) on the Russian module
of the International Space Station (ISS). The BPP is the structure to
which the UrtheCast cameras will be attached.
The BPP was attached to the Zvezda module on the Russian segment of
the ISS on Aug. 22, 2013 during spacewalk #35, conducted by Russian
cosmonauts Fyodor Yurchikhin and Aleksandr Misurkin. The two UrtheCast
cameras, one medium-resolution and one high-resolution, are scheduled
to be launched to the ISS and installed in late 2013.
"We are thrilled with the successful installation of the BPP,"
President & COO Wade Larson stated. "Spacewalks are inherently risky,
so having the mechanism that our cameras will be attached to
successfully installed is a significant milestone."

Hi Ross,
Very feasible, there are a number of CubeSat projects that are trying to do
exactly that.
It seems the problem these projects have is getting a launch - it's not easy.
For example two projects, Project Calliope and Euroluna, will both be
testing Ion Motors. They booked a launch on the same rocket some 3 years ago
now, as yet the rocket hasn't launched.

/
http://amsat-uk.org/2013/03/01/ion-propulsion-euroluna-update-on-cubesat-ht-po
wer-supply/
They seem they are plenty of other projects also planning to use CubeSat
propulsion but in all cases launch availability/cost seems to be the
limiting factor. I'm sure many of these projects will eventually get up
there and who knows maybe one or two might even work as intended first time,
others may need two or three launches before everything is perfected.
I think over the course of the next 5-10 years we should have viable CubeSat
propulsion systems that can go from a 310 km orbit to HEO, may take a few
years of flight to get there but I'm sure it can be done. Of course they'd
need to address the radiation issues that Brent mentioned, although a
CubeSat that simply went from 310 km to a slightly less hazardous 1400 km
orbit would be good.
BTW the Lunar Pocket Spacecraft project, announced in June, is another one
planning to use propulsion, see

Hello,
I am having trouble to understand how Orbitron and WispDDE works to get
right Flipped passes of ISS over my QTH.
Some times when ISS come from South Am?rica and cross over Europe my rotor
need to work flipped, because my stop is North.
Some times he do, sometimes not, then after cross 360? my rotor need to
make a complete turn while is possible to go till 450?.
Here is an example of one pass where rotor is NOT Flipped.

Anyone had the same problem and/or can help me?
Thanks.
Best regards,
Fabiano Moser CT7ABD
