FOR IMMEDIATE RELEASE
Duringthe COVID-19 Pandemic, ARISS to Begin Experimental Demonstrations
ofSchool Contacts using a Multipoint Telebridge Amateur Radio Approach
April28, 2020?AmateurRadio on the International Space Station (ARISS) is
pleased toannounce the first use of a concept called MultipointTelebridge
Contact via Amateur Radio,allowing school contacts for Stay-At-Home students
and simultaneousreception by families, school faculty and the public.
Duringthe last several weeks, efforts to contain the spread of the
COVID-19virus have resulted in massive school closures worldwide.
Inaddition, the Stay-At-Home policies invoked by authorities, initiallyshut
down opportunities for ARISS school contacts for the nearfuture.
Tocircumvent these challenges and keep students and the public safe,ARISS is
introducing the MultipointTelebridge Contact via Amateur Radio concept.First
operation of this experimental system will occur during acontact scheduled
with a group of Northern Virginia Studentslocated in Woodbridge, VA on
Thursday, April 30 at 13:35 UTC (9:35EDT). During this event, an ARISS
telebridge radio ground stationwill link to the astronaut on the
International Space Station (ISS)ham radio station and each Stay-At-Home
student and their teacherwill be individually linked to the telebridge
station. Under theteacher?s direction, each student, from their home, takes
a turnasking their question of the astronaut.
QuotingARISS Chair Frank Bauer, ?Thisapproach is a huge pivot for ARISS, but
we feel it is a greatstrategic move for ARISS. In these times of isolation
due to thevirus, these ARISS connections provide a fantastic
psychologicalboost to students, families, educators and the public. And
theycontinue our long-standing efforts to inspire, engage and educatestudent
in STEAM subjects and encourage them to pursue STEAMcareers.?
ARISSis inviting the public to view a live stream of the upcoming contactat
its new ARISS YouTube Channel: https://youtu.be/Cu8I9ose4Vo.
Duringthe contact, participants will ask as many of the following
questionsas time allows:
1.What does the sun look like from outer space?
2.How comfortable is it to sleep in space?
3.What is one thing you want to eat when you get back to earth?
4.I've heard that stars are red, yellow and blue. Can you see thosecolors in
space when you look at the stars?
5.Besides your family, what do you miss most while being in space?
6.What are your thoughts on our Covid-19 situation right now? Does theEarth
look differently over the last 3 months now that many peopleare inside and
not creating pollution?
7.How often do you get to go out of the ISS? Have you been on any spacewalks?
8.Who makes the rocket that takes you to the ISS?
9.What does it feel like to float all the time?
10.Do you use flashlights on space walks?
11.How do you exercise in space?
12.How do you get out for space walks safely without the air from theISS
coming out into space? How does it feel to walk in space?
13.What do you wear in the space station?
14.How did it feel when you first got to space?
15.How is space different from Earth?
16.What do you study in school to become an astronaut?
17.What do you like the most about being in space?
18.Were you nervous when you launched into space?
19.How do you communicate with loved ones while you are in space?
AboutARISS:
AmateurRadio on the International Space Station (ARISS) is a
cooperativeventure of international amateur radio societies and the
spaceagencies that support the International Space Station (ISS). In
theUnited States, sponsors are the Radio Amateur Satellite
Corporation(AMSAT), the American Radio Relay League (ARRL), the ISS National
Laband National Aeronautics and Space Administration (NASA). The primarygoal
of ARISS is to promote exploration of science, technology,engineering, and
mathematics (STEAM) topics by organizing scheduledcontacts via amateur radio
between crew members aboard the ISS andstudents in classrooms or public
forms. Before and during these radiocontacts, students, educators, parents,
and communities learn aboutspace, space technologies, and amateur radio. For

Yeah, great images!? Say, let's talk 640x480 when you get a chance, just
a reminder and you can reply to my office email address...?? hihi
My recollection is clear since I don't do anything so I am keen to play
with "settings" (intentional no-detail reference) and it be would be
nice to combine it with a resolution change capability as well.
Carrot on a stick in front of everybody, I'm mean without a doubt!?

I don't know if it was mentioned, once the receiver is opened with a
67Hz tone AO-9n does not need to hear a tone with any transmission until
the one minute timer passes at which time the repeater TX stops.?
Hearing a tone with each transmission resets that timer, but it is quite
possible to make a QSO or cause interference during the one minute
without having the tone on your uplink signal.? A repeater output or
whatever other source of an unexpected signal such as a harmonic, could
be heard and repeated if it had better than ~ -120 dBm signal at the
satellite during that time.

It appears to be just a little behind the ISS so I am assuming it is

Subject: [amsat-bb] AO-92 High Speed Data decode questions

<CACymvmczZHa6Xy_kRBc+bU6jthm=Z=0Os8zSNA2YTtKsD7LcKg@????.?????.???>

I tried capturing some of the high-speed data from AO-92 today from the
final 1750Z pass today when the camera was activated. I believe I had some
success, but I am a little confused about what I captured. I did it in two
stages using my phone to capture the raw IQ from my SDR during the pass and
then playing it back on my computer right after into Foxtelem 108z5. The
pass was only 16 degrees at it's peak, but I was able to hear the satellite
down to as little as 6 degrees and Foxtelem reported 24 frames successfully
decoded.
My first point of confusion is I heard QSO what sounded like modem sounds
over the FM downlink intermixed with amateur calls coming through. I assume
that was the high-speed 9600 data mode I was hearing, but this was starting
a few minutes before 1750Z so was the camera mode able to be activated a
little early? Second, is the repeater still active while HS mode is
running? I thought that repeater operation would be disabled to avoid
having voice interfering with the data downlink or is this not an issue?
Last question is, why do I not having anything under the Camera (1D) tab
for AO-92? That tab is completely blank and doesn't seem to have any data
collected. It appears that all frames received are under either the Health
tab or HERCI HK (1D). The recent telemetry for HERCI HK is also all zeros
it seems.
It definitely sounded like there was some high-speed data transfer
happening, something besides the 200 bps DUV signal, but it doesn't look
like I collected anything particular to the Camera operation. Was it not
active during that time or did I just not collect enough frames to assemble
anything?
I still have the original raw IQ capture from the event today.

What you heard was the command station attempting to send the command to
AO-92 to activate the camera.
Unfortunately, there were several stations trying to use the repeater at the
time and blocking the commands being sent to
AO-92.
When the camera is active, the repeater is not available.

Thanks for testing that Eric. Today it's in L/V mode, but tomorrows ~15:25
pass should have a similar time and profile to the ones where there have
been problems.

Hi,
What is the sat name that is used for PO-101 in LoTW? I am also having a
problem but using 11.9. I am manually adding the sat name entry as my
logger doesn?t support sats and using PO-101 but it doesn?t like it.

A little more info please on the camera mode of AO-92 , Is this just a real
time transmission as the satellite is overhead or close by? is it stored and
sent continuously for a predetermined time? I had my station on remote all

Thanks for all the help. I had to update my TQSL and in the update, the
file for PO-101 was also updated. My logging program now works and my
contacts go to LoTW. I will have to remember that TQSL files have to be
updated whenever a new satellite is activated.
