ARISS One Step Closer to Flying New Equipment to ISS
On behalf of the ARISS International team, I am proud to announce
that on Friday September 29th the ARISS team submitted the
InterOperable Radio System (IORS) Safety Data Package to NASA for
review! Our next step in this process is the Safety Review, which is
planned for November 2.
Submitting this was a phenomenal accomplishment!! Particularly
since the entire Safety Data Package was developed exclusively by our
ARISS volunteers---something we have never done before. Prior to
this submittal, all safety packages---from Owen Garriott's in the
early 1980s to today--were developed with contractors from NASA, ESA
or Energia. And might I say at substantial expense. I am pleased
that the ARISS team did it ourselves!
Why is this important? Two reasons:
1) This is a very major IORS milestone. We cannot get to orbit
without successfully completing the safety review process and getting
our hardware certified for flight.
2) Developing the safety package exclusively with volunteers is an
innovative and gutsy approach to keep costs down and get the hardware
flown sooner. Otherwise we probably would have to slip launch 1-2
years while we acquired additional funding to get this done.
NASA Human Spaceflight Safety Certification is a four-step process---
Phase 0, Phase 1, Phase 2 and Phase 3. The material we submitted
covers the first three of the four phases. As part of Phases 0, 1
and 2, we need to make sure NASA understands our design. And we need
to show NASA that we understand all the potential hazards that our
hardware systems could introduce to ISS and how we have mitigated (or
prevented) these hazards. One example is to demonstrate to NASA that
our IORS was designed with electrical wiring and circuit breakers
that possess adequate features and sufficient margin to prevent an
electrical shock or fire on-board the ISS. Critically important
stuff! The final phase (Phase 3) will be complete when we have
completed all testing and NASA inspection of our flight hardware and
NASA deems it flight worthy. At that point the IORS will be flight
certificated and we can fly! Currently we are looking to March-May
2018 for flight readiness.
For those not following ARISS hardware development very closely, we
are developing the IORS to replace most of the on-board radio
hardware. It is called "interoperable" because it is being designed
to be operated anywhere on ISS. But specifically, it will be used in
the two areas with ISS Ham legacy antennas: the Columbus Module and
the Russian Service Module. Interoperability allows us to leverage
existing ISS power cables, it can be moved between modules in the
event of on-orbit failures, and it supports common training and
operations. The IORS is the most complex in-cabin hardware system we
have ever designed, built, tested and flown as a volunteer team. We
will remove the 3 watt Ericsson handheld radio system, initially
certified for flight in 1999, and the Packet module--both of which
have recently had issues-and install a brand-new, specially modified
25 watt JVC Kenwood D710GA radio to enable a multitude of new or
improved capabilities on ISS, including voice repeater and be
tter APRS operations. A key development is the Multi-Voltage Power
Supply (MVPS), which interfaces with multiple electric outlet
connection types on ISS and provides a multitude of power output
capabilities for our current and future ARISS operations and amateur
radio experimentation. It will also allow our Ham Video system to
have a dedicated power outlet, eliminating the outlet sharing we have
now, which shuts down Ham Video at times.
This effort would not be possible without the dedication and
persistence of our IORS development team of volunteers. They have
been working tirelessly behind the scenes to provide an outstanding
amateur radio experience for all. Our IORS development team
includes: Lou McFadin, W5DID, our Chief Engineer; Kerry Banke, N6IZW,
the MVPS lead designer; Bob Davis, KF4KSS, the MVPS Mechanical
enclosure designer; Ed Krome, K9EK, supporting IORS thermal control
and cabin noise dissipation; Dave Taylor, W8AAS, our JVC Kenwood D-
710 development liaison; Bob Bruninga, WB4APR, our APRS and D-710
operations expert; Shin Aota, JL1IBD, and Phil Parton, N4DRO for all
their phenomenal support from JVC Kenwood; Kenneth Ransom, N5VHO, our
operations lead; and our safety package team-Ken Ernandes, N2WWD, and
Gordon Scannell, KD8COJ. Kudos to all on a fantastic effort!
Designing, building and testing the IORS is a huge undertaking and
*very* expensive. We need to build ten (10!) units to support flight
hardware, flight spares, testing, and training across the
international team. Hardware parts, development tools, fabrication,
testing, and expenses to certify the IORS are expected to cost
approximately $150,000. And the hard part (i.e. most expensive part)
is just now starting. So please consider making a donation to ARISS
to take our hardware system from dream to reality. You can donate to
ARISS directly through the AMSAT web site at:
http://www.ariss.org/donate.html. ALL donations go directly to ARISS.
Thank you for all your support to inspire, engage and educate our
youth to consider wireless communications and amateur radio, and to
pursue STEAM careers through our exciting human space exploration and
amateur radio endeavor!

Sputnik Replica - The Transmitter

Frank's Sputnik Replica - The Transmitter
In the January edition of the RAZzies magazine Frank Waarsenburg
PA3CNO continued to report about building a replica of the original
Sputnik 1 transmitter.
In his interesting article he writes about the difficulties and
obstacles he faced: Missing data for winding the coils, errors
in 2p19b datasheets and a critical bug in the schematics. He des-
cribed his approaches to tackle these problems. (See the blog
page for a photo of the project.)
I think for everyone who is interested in understanding the
Sputnik 1 transmitter or who wants even to build a replica Frank's
article is a must read. Please note that the RAZzies is a Dutch
HAM magazine. If you don't understand Dutch simply use the Google
translator or similar tools in order to get a translation.

PE1ITR Posts Impressions and Photos From AMSAT-DL Annual Meeting
http://pe1itr.com/satellite/verslag-amsat-dl-jahreshauptversammlung-
2017.htm
(Ed. note - Google translate helps)
On September 30th I visited with Jack, PA0BOJ, the AMSAT-DL
Jahreshauptvers-
ammlung 2017. We left Bochum at 7:15 am and at 8:00 we were home
again. It
was a long and interesting day, revealing that it was a blast of
activities.
In addition to the usual administrative issues, the central theme of
the
annual meeting was the developments of and around the future Es'hail-
2 satel-
lite. The expectation is now that the satellite will be launched in
Q2 2018.
There were lectures on the construction of the various ground
stations and
their current status. It was nice to see that in the command, ground
stations
built in extensive switching options, which also included space for
experiments.
Also the well-known LEILA is built in custom form and there will be
a websdr
available to monitor the downlink signal.
There was special attention to the digital television capabilities
of this
satellite. In this context I found the reading of Thomas, DG5NGI,
interest-
ing, in which he told me about the DVB-S2 mode that one wants to
use. And
even talked about DVB-S2X as a possible next step afterwards. I had
not
heard of DVB-S2 before, but now I understand that DVB-S2 is more
packet
oriented than DVB-S, so there are more opportunities in the data
stream
build-up. Spoken was about FEC, Modulation, BBFRAMES, Dynamic Coding
and
Transport Capability.
It was also clear that for experimenting with datv on the wideband
trans-
ponder, coordination between users is needed. The BATC is developing a
website that provides more information in this performance.
There was also a dummy S/X band P4A transponder at the meeting. Jack
had taken his DVB-S S-band television transmitter and X-band receiver.
And I'm my ssb/cw S/X band equipment. With this we thoroughly tested
the
dummy transponder. I even made my first qso about this phase4a style
S/X
band dummy transponder with Achim DH2VA, which was on the other side
of
the room. We have therefore exchanged 59 +++ reports. And we were
again
a nice experience richer.

AMSAT Phase 4 Groundstation Report for the Week 3 October 2017
Michelle Thompson, W5NYV, has released the Weekly Report for the AMSAT
Groundstation Team.
https://www.youtube.com/watch?v=tcefTXTj9b0&feature=youtu.be
Her full report, including notes are posted with the video (click on
'See More'). This week Michelle discusses our simplified pi/2 BPSK
decoder, working under the assumption that symbol timing and phase
have already been resolved to a single sample per symbol.
This work fits into the much larger picture of acquiring phase, timing
of symbols, demodulation, decoding, and correlation to the fixed
patterns
of the Start of Frame field in the physical layer header that helps
define each DVB-S2 frame.
The DVB-S2 physical layer header is sent using a modulation scheme
called
pi/2 BPSK. This scheme is defined in the standard. Since we're using
GNU
Radio as our reference design, we decided to make a custom block in
GNU
Radio to do this. This block will evolve to include our specific type
of correlation for the Start of Frame as well.
We started with the definition in the specification where, "SOF shall
correspond to the sequence 18D2E82HEX (01-1000-....-0010 in binary
notation, the left-side bit being the MSB of the PLHEADER)" 90 degree
BPSK, so in complex notation, it's…"The PLHEADER, represented by the
binary sequence (y1, y2,...y90) shall be modulated into 90 p/2BPSK
symbols according to the rule:
I sub 2i-1 = Q sub 2i-1 = (1/v2) (1-2y sub 2i-1), I sub 2i =
- Q sub 2i = - (1/v2) (1-2y sub 2i) for i = 1, 2, ..., 45 "
[Ed. note: examples and explanation are in the video]
Assuming that the demodulation is correct, the next step from here
is to take our start of frame and look for received patterns that
match
it. When this happens, we will produce a tag. Tags in GNU Radio are
synchronized chunks of information that are attached to samples. It
is like metadata that can be used by other blocks. For this block,
we are going to follow the conventions in the general correlation
estimation block. This means that there will be several tags that
can be used by downstream blocks that need them. Those downstream
blocks have already implemented functions that consume the tags, so
if we produce them, it makes for more useful flow graphs.?

COMET Program Training
The COMET Program is pleased to announce the publication of the new
lesson,
"Communicating Winter Weather Surface Impacts
<https://www.meted.ucar.edu/training_module.php?id=1320>". This
lesson will
introduce National Weather Service (NWS) forecasters to the benefits
of
pre-season coordination in understanding the critical needs of
decision-makers, particularly the state and local Departments of
Transportation (DOTs). The strategies used by DOTs to mitigate road
impacts
during the winter and how the NWS can best support their needs are
also
discussed. Learners will gain insight into the common methods of
collaboration between the NWS and DOT, and the different types of
winter
weather events in which they work together. Learners will also
practice
communicating winter weather forecast information that best support
the
concerns of DOT, including working through a simulation to see the
effects
of their communication choices on DOT decisions. The lesson will
take about
an hour to complete (not including the quiz).
The intended audience for "Communicating Winter Weather Surface
Impacts
<https://www.meted.ucar.edu/training_module.php?id=1320>" includes
operational forecasters in U.S. NWS Weather Forecast Offices, and
others
with general interest in communicating weather information. NWS
forecast
offices could use the lesson in their training programs in
preparation for
the winter weather season.
