It's great to hear that there will be opportunities for the rest of us to
contribute later in the mission.
As for now, just like Europe & elsewhere there are a good number of amateurs
in the U.S. collecting telemetry as their primary satellite activity every
day. Of course, effective range, equipment capabilities, and hours
dedicated to the hobby vary but there is a LOT of data collecting potential
out there... nearly world-wide.
So, the visibility window is essentially all the time.
While out-of-date and VERY roughly done, you might get a kick out of an
effort that I made some time ago to document the coverage provided by
amateur operators contributing telemetry to the DK3WN/PE0SAT database at
that time:
http://www.qsl.net/k/k4kdr//files/Amateur-Space-Network.png
(Imagine how much more complete that coverage actually is if you add the
stations I missed, or who have become active since I made that map!)
In the U.S., specifically, I see that there are very high D-SAT passes in
the prime evening hours coming up for us over the next several days... the
area of 10pm-11pm local time over the East Coast & 1 1/2 hours later over
the Western U.S. For people who work during the day and are more active
with hobby activities in the evening, of course this is ideal.
So, if you have any needs or special activities that you have been holding
to test other than when over Europe (or for longer duration than a single
pass over your location), the area of 0230 UTC will find D-SAT high in the
sky over the Eastern U.S. should that be of any interest to your team.
Finally, many of us have worked (and ARE working) directly with cubesat
teams to transmit commands UP to satellites for various reasons that were
useful to their projects. I would encourage you to reach out to any of us
that are located in positions favorable to your orbit if there is ever an
opportunity to add value to your project.
Thanks for the info!

Hi Scott,
Thanks for the congrats.
Actually D-SAT?s transmission can be triggered by telecommand or by a timer.
During this initial mission phase we have communicated only over the Europe
but if we know that there are people that are ready to listen to D-SAT in
the US we can absolutely schedule some dedicated transmission over that
area. For instance, we can schedule a SatAlert experiment transmission and
some telemetry transmissions.
We just need to know when your visibility window starts ? !!
The involvement of radio amateurs in the U.S. could be much greater during
the decommissioning phase because we are interested in collecting the
telemetry data that will then be automatically transmitted during the
re-entry trajectory. The final reentry maneuver, planned during the first
week of August, will be activated the Italy, where D-SAT will start lowering
its altitude, it will then pass over the North Pole to finally it reentry in
the Pacific Ocean (closer to Hawaii).
I hope this was helpful. Let me know if you need more information!
Sincerely,
Alessio

Oggetto: Re: [amsat-bb] D-SAT Mission
Congratulations on your project so far, Alessio.
I have a question, please...
Does D-SAT transmit over locations other than Europe?
I have seen great posts from others reporting reception of D-SAT, but over
the U.S., I have not had any luck receiving the satellite.
If only SOME of the possible data is transmitted outside of Europe, it would
be helpful if you would like to provide a list of what one might expect to
receive.
Thanks very much!

Subject: [amsat-bb] D-SAT Mission
Dear Sirs,
my name is Alessio Fanfani; I'm a young telecommunication engineer and an
enthusiastic Italian satellite amateur (callsign IU5CRE).
Three years ago I started to work with D-Orbit, an Italian aerospace
company, on an ambitious CubeSat mission called D-SAT.
D-Sat is a three-unit CubeSat designed, built, and operated by D-Orbit and
it will be the first satellite in history that will come back into Earth's
atmosphere in a safe and controlled way by means of a dedicated solid rocket
motor and burn up instead of becoming new debris.
D-SAT was launched on June 23th, 2017 into a 500 km sun-synchronous orbit
from Indian SHAR.
D-SAT is now fully operative in orbit and it is hosting three communication
experiments in collaboration with an Italian university, high-level schools
and a local hamradio community.
For more information on D-SAT, you can visit the mission's website
(www.dsat.space), where you will also find a page entirely dedicated to
radiohams (www.dsat.space/radiohams) where you can download the software
necessary for the reception of D-Sat's signal.
We really hope you will consider joining us! Also, should you have any
question about the mission, don't hesitate to ask!
Thank you for your time and consideration.
Sincerely,
Alessio Fanfani, IU5CRE

Message-ID: <4571b02d8bbbb40a36a5f6a0663acd7a@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset="UTF-8"
PRESS RELEASE:
The QIKCOM-1 module containing an APRS transponder and Terrestrial Alert
beacon will be deployed from the ISS on 21 Aug 2017.
http://aprs.org/qikcom-1.html
Built as a student project Amateur Satellite module at the Naval Academy,
and attached to the NovaWurks SIMPL spacecraft, it will function identical
to the ISS transponder on 145.825 with the same ARISS alias and once they
widely separate, will permit possible dual-hop experiments between it and
the ISS APRS digipeater. See page.
A second experiment is a terrestrial alert beacon on the North American
continent APRS frequency of 144.39*. This beacon can alert mobile
operators doing normal APRS activities that the spacecraft is in view and
that they can QSY to the space frequency of 145.825 for a quick satellite
operation. A European beacon was also planned, but is disabled due to lack
of consensus, and only the two A/B frequencies were possible in the
hardware. This unconventional operation was coordinated in 2014 prior to
the IARU change in policy in 2016 that will no longer coordinate such
out-of-subband operations.
The module and host SIMPL spacecraft have been on the ISS since December
2015, but not deployed due to a SNAFU with the FCC.
Although this is the date of the Great North American Solar Eclipse, as far
as we know at this time, this scheduled deployment has nothing to do with
the Eclipse. But tens of thousands of hams will be out in the field that
day to observe the eclipse, so remember to bring your APRS HT with you and
listen for QIKCOM-1. (Release time is unknown at this time). It is 4
Watts and should be hearable on an HT.
Bob Bruninga, WB4APR and
Todd Bruner, WB1HAI control operator.
* As everyone knows, the terrestrial 144.39 frequency is wall-to-wall
packets in most populated areas and the chance of hearing the QIKCOM-1
module is small, but remember, those people who are driving in remote areas
who are NOT hearing wall-to-wall packets, will have a high probability of
seeing the beacon. And it is these remote travelers, far from the
terrestrial network that are the ones that might need a satellite to get
their message out!

John, V47JA, reports that his FT857 failed
yesterday during a SO-50 pass when he was about to
call N8HM. He will be looking to borrow a UHF
receiver from someone on the island to get back
on SO-50. He will also be returning to St. Kitts

1/4 Wave stub lesson learned.
I always wondered exacly where one measured a ? wave coax stub.. the
shield, or the total connection length to the center coax?
ANSWER: The length of the center wire makes a difference.
We had poor second harmonics from our Cubesat VHF transmitter. Carefully
built a prototype shorted ? wave stub and tweaked it to over 26 dB of a
notch at the second harmonic. But then to install it on the cubesat
transmitter board, we couldn?t quite get the prototype coax to fit right at
the transmitter connection and had to extend the center of the coax about
1/8?.
This detuned the stub by over 5 MHz at the 145 MHz operating frequency
though the length of the shield remained the same.
Now I know. Everything counts!
Fortunately it detuned it lower so I have two more cuts available on the
flight unit to bring it in?

Packet Module status on board ISS
ARISS has received several reports stating that the packet system on ISS is
down. Here is what we know and our current forward plan.
The packet system in the Columbus module started to act up late last week,
sending only a beacon. The ARISS team requested a power recycle by the
crew, and with that power recycle, the packet system appears to have stop
functioning completely. Note that this unit has been on-orbit for 17 years.
It was launched on the STS-106 Space Shuttle Atlantis mission in September
2000 and was built, tested and certified for flight about 20 years ago.
The ARISS team has had some extensive discussions on the way forward. We
would first like to do some additional troubleshooting with the existing
packet module. It will take some time (weeks) to develop troubleshooting
procedures, get the procedures approved by NASA and then conduct the tests
with the crew. This includes an additional power cycle. The turnaround
time is much longer than usual because a new crew will soon be arriving on
ISS. The current crew is focused on the new crew arrival and there will be
about a one- to two-week transition after the new crew arrives. On the
positive side, one aspect of our troubleshooting-a second power cycle-will
occur automatically because ARISS is shut down during crew docking and
turned on afterwards. However, there will be more to our troubleshooting
than just the power cycle.
We have some additional plans with alternative solutions, but those are
currently being discussed and prioritized within the ARISS team. All
solutions will require international ARISS team coordination, additional
procedures and crew interaction. People who have carefully followed ISS
operations know that crew time continues to evolve with the more extensive
research that is occurring on-board. Suffice it to say, it will take longer
than what it has taken in the past to work through this issue.
The above information is to make sure that ARISS properly sets expectations
on how long it will take to resolve this. At this point, expect a few
months with no ARISS packet.
As you all can see, deploying the Interoperable Radio system that is
currently under development by ARISS has become even more critically
important. The ARISS team is laser focused on getting that system developed
and deployed. We are conducting a final design review with NASA on this
system next week. But we cannot get to the finish line without your help.
If you can, please consider a donation to the ARISS radio fund by clicking
on the ARISS donate button on the ARISS web page (www.ariss.org) or the
AMSAT web page (www.amsat.org). All donations, large and small are
appreciated.
On behalf of ARISS, we thank you for your sustained interest and support of
our program.
Sincerely,

About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and the National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies and
amateur radio. For more infor
mation, see www.ariss.org, www.amsat.org, and www.arrl.org.
