Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at West Michigan Aviation Academy, Grand Rapids, MI on 22 Oct.
The event is scheduled to begin at approximately 17:14 UTC. It is
recommended that you start listening approximately 10 minutes before this
time. The duration of the contact is approximately 9 minutes and 30 seconds.
The contact will be direct between NA1SS and W8ISS. The contact should be
audible over portions of the eastern U.S. and adjacent areas. Interested
parties are invited to listen in on the 145.80 MHz downlink. The contact is
expected to be conducted in English.
The West Michigan Aviation Academy is a tuition-free public charter high
school founded by Dick DeVos upon encouragement from wife, Betsy. Stemming
from their passion for both education and aviation, the school opened its
doors in the fall of 2010 and is located on the grounds of the Gerald R.
Ford International Airport. Like other high schools, our curriculum
includes core subjects. But as an aviation-themed high school the curriculum
at WMAA is designed for students who have a passion for aviation and/or an
interest in science, technology, engineering and mathematics. (STEM)
The Aviation program includes training for the Private Pilot certificate in
the student's senior year. The school owns our own Cessna 172 that is
provided at direct operating costs to the students. Although they must pay
for the flight training the total cost is much lower than renting at the
local flight school and ground instruction is provided for as part of their
elective classes. Currently we have 11 students in the program and hope to
have 18 by the time of the contact. We also try to get the kids out around
the airport to experience the many different job opportunities available in
aviation.
The Robotics program includes FIRST robotics programs and many of our
competitors are taking both engineering and aviation classes. Our
engineering program provides for instruction in aerospace, robotics and
electronic fields. We try to closely alley the Aviation and Engineering
departments.
We currently have about 500 students were everyone knows each other. We have
students from all walks of life from the suburbs to the inner city all
working together and enjoying the diversity this environment offers.
Participants will ask as many of the following questions as time allows:
1. What courses did you take in high school that you find most relevant to
your work at the International Space Station?
2. Are you planning on expanding the size of the ISS, if so then when do you
plan on starting the constructing?
3. So far during the twin study, what research has been recorded since Scott
Kelly was sent up to the station?
4. What do you think of the liquid water on Mars? Do you think it would make
it possible to colonize it earlier?
5. Waking up in space every day and seeing earth out your window, how has
seeing this and having this opportunity changed your perspective on life?
6. Concerning the twin study, in order to remove variables from the research
on gut organisms, will the twins have the exact same diet during the
space mission?
7. Could you use a gyroscopic space station to simulate gravity so the
astronauts can still maintain balance and bone strength?
8. What are the ways you blend your culture with the other cultures
surrounding you at the station?
9. Do you always have enough food? If not, how is more food sent to you?
10. Being confined in that small area so far away from others, do you guys
ever feel lonely? How are the group dynamics?
11. How does space positively or negatively affect your health?
12. What is the daily checklist for astronauts, in terms of safety
inspections, instrument tuning, and/or incoming information?
13. What types of plants do you grow to study and what are the main
differences between their growth in space and on earth?
14. What kind of emotional impact do you feel being selected out of
thousands of scientists to be one of the few humans to venture into
outer space?
15. Does zero gravity affect your dreams?
16. I understand most astronauts stay in space for approximately six months,
do you feel that astronauts should be kept in space for this long or
should it be longer such as Russian astronauts who have been
known to stay for a year?
17. In your opinion, do you think that commercial rocket companies such as
SpaceX will help the space industry by exploring new realms of our solar
system, or will the cheaper, reusable rockets hurt the industry by
causing a fatal accident?
18. Does Scott Kelly have to do anything different while in space to gather
data for the identical twin/effects of space study?
19. What does a lunar eclipse look like up at the space station?
20. How does having women on the ISS impact the mission?

> An ISS school contact? in Michigan on 22 Oct.
> ? to begin at approximately 17:14 UTC.
This is a great time for those skilled portable "arrow" operators to get
data on using fixed vertical arrow beam antennas for ISS voice at or near
the horizon.
The test will show if well placed fixed tripod "arrow class" antennas at AOS
and LOS and a central turnstyle could possibly make it easier than a full
AZ/EL Oscar class antenna at the school.
Testers, Please read the concept paper at http://aprs.org/aos-los-test.html
If your QTH is west of Michigan, then you should test your LOS horizon. If
your QTH is east of Michigan, then you should test your AOS horizon. This
is because we want to make sure we are getting voice quality data AT the
horizon while the ISS crew is actually speaking.
The desired data is a minute-by-minute log throughout the pass of ISS signal
quality (noting nulls or fades) without moving or adjusting the antenna.
Your receiver must be right near the antenna (no coax loss). Just orient
the beam vertically with an up tilt of 15 degrees. Then aim it at a fixed
Azimuth that is half way between AOS (or LOS) and when the ISS rises above
(or drops below) 30 degrees elevation to cover the first (or last) portions
of the pass.
Leave your antenna fixed throughout the pass. We need to know how well the
squelch on your radio eliminates the weak signal when the ISS is outside
your particular fixed beam too.
In a real scenario of this full technique, above 30 degrees the ISS is 3
times closer and 10 dB stronger and would be heard fine on a central omni
antenna. But that is not part of your horizon performance test. So be sure
to choose a good low horizon *and* the horizon you share with the School
contact in Michigan so that there is ISS audio during your particular
horizon crossing (AOS or LOS).
An audio recording would make it easier to prepare the log after the pass or
you can just make checks or X's every 5 seconds on a piece of paper and
summarize it later. Do NOT run open squelch. Set the squelch for normal
ham radio operation to silence the radio when the signal would be
unintelligible anyway, since we would not want unintelligible noise from one
receiver to distract from good audio from the possible others..
If this concept works, then the idea would be to bring in all three receiver
speakers (left-to-right) into the auditorium operating position to give
equal weight to each receiver but also give a sense of the passage of the
ISS. If this test shows any promise, it could not only eliminate all the
complexities of long crossed yagis, AZ/EL rotators, big masts and active
tracking, but also completely eliminate the problem of long runs of coax
from the school gymnasium to the antennas. The coax is eliminated by
placing 50W mobile rigs (capable of cross band repeat) at each of the
possible three antennas and operating them remotely via 3 UHF HT's indoors
on-stage (coupled into the sound system).
So, if you are in range of this Michigan ISS school contact, and you have an
arrow on a tripod at your QTH, you could collect data on a horizon
transition to see if this idea is a possibility.
Again, YOU ARE RECEIVE ONLY. Your test is *independent* of the actual
school contact, you are just taking your own receive data wherever you are
of how well a FIXED arrow on a tripod can hear the ISS at low elevations.
Be sure to find a place with a good horizon at AOS(or LOS) to set your
antenna.
If we learn that there will be any significant fades or loss of signal, then
this idea fails... But if it works, then the two arrows, tripods, three
crossband-repeating mobile rigs and three UHF HT's could be made into a
suitcase GOKIT to standardize some school contacts with a lot less work.
Just an idea

Anyone know why the upcoming ARISS contact in Michigan is not listed on the
ARISS.org website? I was trying to tell a friend about and I suggested he
check out the website. The website is not up-to-date. Kind of embarrassing,
I would think.
Is the contact going to be streamed live on any websites?

Probably because the person who maintains that site is on vacation and not
due back till later this week.
The contact in Grand Rapids is scheduled for Thursday, Oct. 22 at 17:15 UTC.
It is direct, so the downlink will be audible in that part of the country.
I have not heard if the school will be streaming it. This has been
announced on amsat-bb, with school info and the questions to be asked.
There is also a direct contact in Dearborn the following week, on Tuesday,
Oct 27 at 16:02 UTC.

Do satellites have sex?
Er, I mean, well ... nautical ships are referred to as being female - "she."
Does Fox-1A have a gender? When I called it "her" in a recent post,
I was asked if it really had a gender.

Steve,
Typically the audio from a telebridge contact is carried on the AMSAT
Echolink server and on the web. Direct contacts in the US are a little
more tricky to get the audio out from the school via phone patch or skype.
Also it's felt to add more to the stress level of the ground crew, we'd
rather have them make a good contact for their local use. I've generally
added that capability to the directs I've done personally and I'll tell you
its a good half a days work to do it. At one school I has 150 feet of Cat5
strung around the gym to get to the stage and on another we tried the
Iphone app. Never got any reports so I don;t know how well that worked. we
were lucky to get a signal in that school. The gear we used was the same
from school to school, which is not the norm.

Is it possible to work duplex with an Elk 2M/440EL antenna and two HT's,
one programmed with VHF up link and the other programmed with UHF down link
.... SO-50 for example?
Since the Elk 2M/440EL is designed for two bands, but only one coax
connection, how would this be done?
Thanks
Loon

Get yourself a duplexer:
http://www.radioworld.co.uk/mfj-916b_mfj_2m_70cm_duplexer
I am not sure which radios you should use but beware of de-sensing one
with the transmissions from the other.
If using two radios an arrow without the duplexer is the equivalent as
it has 2 feed points. And elk with a duplexer may work better than an
arrow with no duplexer as there is additional filtering in the
duplexer, which the arrow would not have, when using 2 radios.
So basically the elk has only 1 feed point, to use 2 radios get a duplexer.
The arrow has 2 feed points, and has an option to add a duplexer to
combine them to give one feed point for a single radio use. Having a
duplexer in line may help with de-sensing.

I wanted to announce the release of FoxTelem Version 1.01. If possible,
everyone should upgrade to
this new version. In addition to some new functionality it fixes some bugs
and issue that mean
more data will be uploaded to the server.
This is a patch release. If you already have 1.00 installed then download
the file FoxTelem_1.01_patch.zip
You can download it from:
http://amsat.us/FoxTelem/windows
http://amsat.us/FoxTelem/mac
http://amsat.us/FoxTelem/linux
Only two files have changed (plus the manual). Copy these files into your
install directory
- FoxTelem.jar
- spacecraft/FOX1A_radtelemetry2.csv
You can also download the whole install file and install it in a new
directory. You can use the
settings menu to continue using your existing log files. Ask if you need
assistance.
Lots has changed in this release and many bugs have been fixed. Please
report any issues
that you see.
Release notes:
* Allow the user to view and set the "track" attribute for each spacecraft
(and other parameters)
* Better doppler tracking in IQ mode and more stable estimate of the
received frequency
* Better Find Signal algorithm with tuning paramaters for experts
* Read Time Zero from the server for each reset and use to plot graphs in
UTC
* Set the default fcd frequency to 145930 so that Fox-1A, Fox-1Cliff and
Fox-1D will be in the passband
* Allow the gain to be set on the FCD (rather than hard coded)
* Do not change the FCD LNA or Mixer Gain. Leave unchanged.
* Do not open the FCD unless the start button is pressed
* Fixed a bug where the last 2 bytes of the radiation telemetry were not
decoded correctly
* Allow Vanderbilt radiation experiment to be graphed
* Allow user to select UDP or TCP for upload to the server (but use UDP
for now please)
* Shorten the period between passes so that graphs look continuous
* Ignore duplicate high speed radiation frames - needed for processing
data from the server
* Allow graphs to be hidden so that average or derivative is easier to see
* Notify the user when a new release is available
* Cleaned up the FFT trace with some averaging
* If showRawValues is checked then save CSV files as raw values
* Several updates to the manual
