New subject: [amsat-bb] Re: The Whole GEO Package - EMCOMM

20 Dec 2007

      The notion that Maybe ARRL should be the driver(s) of GEO's
for emergency satellite radio flew past a moment ago.
At least it would appear the issue is larger than just AMSAT-NA

I actually equate the preparation and package to being a combination 
of the
previous efforts of Civil Defense and MARS (not the planet.)
During the Cold War the government funded the placement of 2 meter 
Gonset
Communicators in many CD Shelters and city/town communication 
facilities
around the country. Nets were held. Groups were formed.
Currently I do know that, at least in Massachusetts, there is still 
funding
available to the towns for a "Civil Defense" director in the local
governments.
So...as part of the EMCOMM..."Civil Defense" services are again 
strengthened
through a local "Communications Officer", the old lessons of traffic 
passing
are updated and practiced ala "MARS" TYPE traffic nets (though not 
under
Military oversight), new "standards" are set, satellite "nets" are 
formed
for readiness training allowing the development of "systems" and as 
usual
"emergency traffic" gets priority.
This may preclude 100% access by the casual operator during "net" 
evenings,
but assuming timezone differences and a sufficiently wide passband, 
these
"CD" nets might be held one day/night per week.
In this case, we prove and provide capability, develop a "league" 
of
operators who can become EMCOMM qualified while allowing themselves 
and
others to use the satellite "freetime" while developing their skills 
at
disaster relief if they so choose.
Previously these activities came under the "umbrella" of the ARRL. 
That
would be one solution, however there is a real possibility that this 
becomes
an opportunity for AMSAT to step up and drag EMCOMM kicking and 
screaming
into this century.
Will it require more of an organization, yes...will it require more
"members"...yes,
but the opportunities for digital to pencil traffic handling and
communications are endless.

analysis of the situation.
I believe the proponents of the Intelsat agreement have done us a
great

service by identifying a real and persisting need which AMSAT
can
uniquely

fulfill. By doing so, they not only greatly increase our chances
of
funding

otherwise prohibitively expensive launches, they give our branch
of the
...

hobby a greater reason to do what we do.
However, I also think the EMCOMM branch of our hobby has
different needs
...

than the usual satellite station operator. If we are to really
and
honestly
...
...
make the world a safer place and save lives, I think we will need
to
...
...
provide a GEO EMCOMM package that will require us as a
organization to
...
...
branch into some new and exciting efforts. Let me explain what I
mean.
...
...
Traditionally, a satellite station has been developed through
one
person's
...
...
expertise gradually growing regarding a number of interrelated
aspects:
low
...
...
signal VHF and UHF operation; the mechanics of an az-el antenna
array;
...
...
computer control; and doppler correction. Certain satellites or
operating
...
...
habits allow one to omit one or more of these, but in general
it's, even
by
...
...
ham standards, a challenging array of new skills and
understanding. I'd
say
...
...
the members of AMSAT are self-selected as those who enjoy this
challenge
...
...
and seek to learn as many aspects of the field as possible.
However, for an EMCOMM system to be effective, it cannot rely on
a broad
...
...
array of such specialized knowledge: it is unreasonable to expect
that
the
...
...
first ham on the scene of a disaster will be one of the AMSAT
'us', a
...
...
person who has acquired this specialized knowledge. It is only
reasonable
...
...
to assume that it will be an amateur radio operator, familiar
with the
...
...
general principles of radio theory and operation. In fact, in my
region t
he
...
...
EMCOMM specialists and the technical specialists (if I might put
it that
...
...
way) are often not the same people.
So our challenge is more extensive than the challenge that faced
AMSAT
with
...
...
any previous launch: we need to make communication through this
bird
...
...
possible for any ham shmoe who is opening up a box of equipment
after,
say
...
...
an afternoon of instruction half a year ago.   Please note, this
is not a
...
...
matter of dumbing-down the bird or making it uninteresting. In
fact, for
...
...
the old-hands and the technically adept around here this will be
very
...
...
interesting and a great outlet for our skills. In this
application, if
not
...
...
on all birds, we should take it as a sign of success when people
effortlessly get connected, because it would mean that, in a
true
emergency
...
...
there would be a greater likelihood of useful service.
If this analysis is accurate, we need to imagine, broadly, three
things:
a)
...
...
the services (or modes) this ham will offer to support EMCOMM; b)
the box
...
...
of stuff that this ham opens up; c) the afternoon's training she
undertook
...
...
to know how to use it. These are interrelated, of course. The
training is
...
...
apropos the box of stuff, and the box of stuff allows the
services. They
...
...
should also, I think, be *standardized* to an extent that has not
been
the
...
...
case before with satellite work. Recently I heard the argument on
Amateur
...
...
Radio Newsline that ham EMCOMM services should be more
interchangeable
...
...
across the continent; the same will surely be the case regarding
this
work.
...
...
Ideally the 'stuff' and the training is the same everywhere so
that the
...
...
shmoe has a chance of recollecting her training and is required
to factor
...
...
out/in as few local variables as possible.
The advantage we have is that it isn't unreasonable to expect the
box of
...
...
stuff to be perhaps more pricey than individual hams would like
such
things
...
...
to be.
A large part of a) and b) will be determined by the ACP team,
whose goal
...
...
even with Eagle was to provide ground-station hardware alongside
the
bird's
...
...
hardware. (The wisdom of this new approach should be applauded;
I'm sure
it
...
...
has made re-purposing Eagle hardware for P4/EMCOMM much easier
to
imagine.)
...
...
As I've argued before, I think one of the most important mode we
can
offer
...
...
is simple Internet connectivity, allowing the emergency services
folks to
...
...
use the communication tools like email with which they are most
familiar.
I
...
...
hope this will be part of the mix. As for the second half of b)
and c), I
...
...
think it will focus around designing and teaching the use of
software.
...
...
Perhaps the box of stuff will include a laptop that operates well
with a
...
...
specialized linux distribution-on-a-disk, including all the
software
tools
...
...
needed to assess link quality, perform simple communication, etc.
If I'm
...
...
right, this is fortunate because we seem to have quite a number
of adept
...
...
software developers in our midst.
Finally, the course. Can we provide standard lesson-plans, ppt
slides and
...
...
the like? I think this would significantly lower the bar on each
of us
...
...
teaching a session on P4 to our local club or EMCOMM group.
I think we should spread the load on these tasks as early as
possible,
...
...
making many of us participants in the final goal of increasing
the safety
...
...
of our communities and nations. I'm excited to hear what others
think
about
...
...
the broader implications of the P4 initiative and how we can
deliver on
the
...
...
whole GEO package.

Bruce,
This is an excellent topic to bring to the -bb.
Off course until the design of P4 has progressed, this is mostly
speculation.
...
The EMCOMM radio package will most certainly drive the satellite
requirements, as well.
The ground package needs to be:
1- compact (portable)
2- standardized (so diverse groups can assemble a package)
3- well documented (both for assembly and use)
4- versatile to power (anywhere in the world)
5- robust (to endure rough handling; harsh environments)
6- easy to interface (with computing hdwr; telco; other ham
equipment)
...
7- simple to assemble and aim
8- affordable
9- kit or ready to use (within reason considering the technology)
This should probably be close to the same package that the
apartment
...
user will have.  This would expand the volume of units made.
design
...
be made available to commercial sector to provide units (fitting
the
spec).
...
Hope this gives a starting point.
