Message to US Educators
Amateur Radio on the International Space Station
Contact Opportunity
Call for Proposals
Proposal Window February 15 ? April 15, 2017
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew
member on board the ISS. ARISS anticipates that the contact would be held
between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits
will
determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of
participants and integrate the contact into a well-developed education
plan.
The deadline to submit a proposal is April 15, 2017. Proposal information
and documents can be found at www.arrl.org/hosting-an-ariss-contact.
The Opportunity
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.
An ARISS contact is a voice-only communication opportunity via Amateur
Radio between astronauts and cosmonauts aboard the space station and
classrooms and communities. ARISS contacts afford education audiences the
opportunity to learn firsthand from astronauts what it is like to live and
work in
space and to learn about space research conducted on the ISS. Students also
will have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight and
the complexity of scheduling activities aboard the ISS, organizations must
demonstrate flexibility to accommodate changes in dates and times of the
radio contact.
Amateur Radio organizations around the world, NASA, and space agencies in
Russia, Canada, Japan and Europe sponsor this educational opportunity by
providing the equipment and operational support to enable direct
communication between crew on the ISS and students around the world via
Amateur Radio.
In the US, the program is managed by AMSAT (Radio Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with
NASA and
CASIS (Center for the Advancement of Science in Space).
More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

Nah Dave,
that's not big, just a scaled down version of e.g. this one (for
~22 MHz, reception of Jovian storms, built by OH8PX, SK):
http://www.rfshamaanit.fi/hf_helix_1.jpg
Your impedance is about right too, but there are several neat ways
of getting this matched to 50 ohms in a fairly broadband manner,
easily googled.

I have a question,
In Orbiitron, I get when I start the program the pop-up that tells me to
UP-Date the TLE's With a YES / NO set of buttons.
Now someone a few weeks ago showed me with Teamviewer How to do this
manually, and it has worked greatly ever since.
But to do that I have to tell this pop-up "NO" and then do it manually.
Thing is if I say "YES" it messes up the whole program, and takes a
while to get the TLE's working correctly again.
Any idea why this should be?

Hi Joe,
I do not exactly know what problems you encounter, but a common
pitfall is that Orbitron does not have the correct persmissions to
download TLEs to the default folder (program files / orbitron/ TLE).
To solve that, run Orbitron as administrator. It should pick up
sufficient rights to write to the TLE folder.
Workaround 1: install Orbitron somewhere out of Program Files
Workaround 2: put the TLEs somewhere out of the Orbitron TLE folder.
Hope that helps

Hi Wouter,
And everyone that has replied directly.
I always run the program as Administrator.
If I did not want to mess it all up, I'd do a screen video capture to
show ya all what happens.
But the first time it took me months of fighting this thing and never
could get it to work till the one chap did the team viewer thing and
fixed it.
Sorry, Just thought it might be a common problem. That others have
experienced.
I just keep saying no, then click on the manual way and do it anyway.

Very interesting Phil, it seems to make sense that this calculation could be
used in reverse to calculate the energy needed raise the perigee height of a
GTO orbit. Assuming a flight to GTO was available to a 1U or 3U cubesat, if
the perigee is not raised the satellite will not stay in orbit very long, if
I understand it correctly. Given the limited size of the spacecraft and the
prohibition on volatile propellants this poses a difficult challenge. It
would be interesting to determine if enough thrust can be generated by
electrical thrusters to accomplish this ?

Subject: Re: [amsat-bb] BY70-1
Here's a first calculation of the power dissipation in BY70-1 during its
decay.
The highest will be for the period between the last two sets before
decay, which have epochs:
Fri Feb 17 17:37:01.530336 2017 UTC
Fri Feb 17 22:00:25.286112 2017 UTC
i.e., roughly 4.5 hours apart. The specific orbital energy at the first
epoch was -3.044e7 J/kg and -3.054e7 J/kg at the second.
The energy decreased by 100 kJ/kg during this time, so over 4.5 hours
that's an average of about 6.2 watts per kilogram. Multiply that by the
(unknown?) mass of the spacecraft to determine the actual drag power
dissipation in watts.
Depending on how much of that heat was conducted into the spacecraft, I
suppose it would have shown up as a temperature increase in telemetry
but not necessarily enough to cause the electronics to fail.
Decay was about 2.25 hours after the last eleset, and obviously the
power dissipation rose quite sharply toward the end of that interval...

Hi,
For those that have been following the WOD you may have noticed that the PA
Temperature has been displaying some strange numbers.
These were an artefact of the data handling in the warehouse. Now fixed and
were getting sensible data displayed.
Many thanks as always to people who have been sending us data. It has been a

My apologies for some short outages over the past few days as I've been

Content-Type: text/plain; charset="iso-8859-1"
Hi folks,
I have just changed the sat into amateur (continuous transponder) mode.
Plan is to switch back to auto mode on Sunday 26 Feb 2017 pm UTC as usual.
See https://funcube.org.uk/news/ for details of new FUNcube launched last
week, and Pls see below for other FUNcube transponder info
Have FUN with the transponder.
73s Jim G3WGM and the FUNcube team.
AO-73 FUNcube-1
The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)
The nominal transponder frequencies are:
Uplink: 435.150 - 435.130 MHz LSB (Inverting)
Downlink: 145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK
(The passband may be up to 15kHz higher depending on on-board temps. Low
temperatures give higher freqs!)
FUNcube-2 aka FUNcube on UKube
The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with
about 70mW output. The FUNcube-1 Dashboard does not correctly display the
telemetry but it
does correctly decode the data and uploads it to the FUNcube Data Warehouse
from where
it can be examined. Most of the real time data channels are operational and
these include
battery voltages, temperatures and ADCS data coming via the main On Board
Computer (OBC).
The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter
sends its CW beacon and, occasionally, for a few seconds when the main OBC
reboots (approx seven times each orbit).
The nominal transponder frequencies are:
Uplink: 435.080 - 435.060 MHz LSB (Inverting)
Downlink: 145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK
(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)
EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.
The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB
Further detailed info on EO79 transponder frequencies is at:

All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

February 24 - ISS digi on 437.550 was ON during afternoon passes over
Chicago; successful digipeat copying my own packets.
Also noted that NO-84 telemetry reports APRSON status on 145.825. Waiting
for the pass at 1621 within range of Chicago to give it a try.
