I often wonder, is it is not possible to configure any of these 
"non-functioning" satellites to suit our needs?  I mean we can do an awfull lot 
with very little.  There are alot of "non-functioning" satellites up there.  We 
are a creative bunch and enjoy the challange.

About the only thing we could do is use them as training guides for
receiving weak signals.  Satellities are not designed to qsy, or do
anything other than they actual function(s), specified long before
they were ever built.  Add more to a bird increases complexity, and
also failures.

I'll bet they turned it off to free up that frequency for something
else.  If that is the case then we can't even really try monitoring.

I've often wondered about the ham community using old systems
but except for really rare cases, they are just too specific to do
anything for us.

I know it would be expensive but on the "if you spread your net wide 
enough" view of thinking, could we not approach commercial satellite 
projects prior to launch and bung a transponder on them only to be used 
when the primary mission fails? OK, so you might win some, might lose 
some and I know it would be expensive but it seems better than the 
situation we have now, plus we could be potentially building in some 
long term birds that would replace the current ageing fleet. It would be 
a long term view, but it would be something!

Presumably this has been brought up before but no harm in re-hashing it 
for any new ideas especially with the BoD voting soon to happen! :-D

Thats a neat idea.  We'd have to build the whatever to the physical
specs provided, and pay for the extra fuel needed.  Sadly, I think
in order to make this work we're talking real money, but perhaps I
am wrong.  Perhaps there is a tax-writeoff somehow?  I'd like to

This sounds like the AMSAT-Intelsat deal except that the Intelsat agreement 
would allow the amateur payload to operate in parallel with the primary 
payload. A number of the RS series amateur satellites also operated this 
way.

This is an intriguing possibility and perplexes me somewhat they (AMSAT)
hasn't mentioned it, or something similar. For instance, every launch has a
ballast load. Why is it that the ballast cannot be replaced with a cubesat?
Why aren't commercial sats required to have a amateur band transceiver
installed, as mentioned here and elsewhere, to activate when the primary
mission ceases? Public utility companies and regulated companies such as
AT&T help us routinely.

Of course the easy answer is 'no', but a thoughtful consideration from the
people who deal with this on a daily basis might be more nuanced. It's not a
technical issue, is it?

Moreover, rigging a series of sats with a transmission system that switches
on in the event of catastrophic failure or switching off of the main system
offers the possibility of establishing a sat network capable of vast
distance datacom at no expense to the primary carrier and of great benefit
to the general public and science.

Isn't it time we move to working on a deep space internet system that the
commercial folks don't want to spend a lot of money on, and that we (ham
folks) can help by proving-in the concept? Seems to me we can do this
without a lot of expense but with the foresighted help of the commercial
folks.

This whole discussion relates back to Bob's proposed idea of having several

to launch.

I think that'd be the place to start.

2009-07-01 Thread James French 
To go off in another direction with this, what would it take to start
our own Deep Space Network for reception and control of some of these
older Deep Space or Near Space craft?

I know that there was a LOT of talk about the Stereo mission and helping
out with reception back a few months ago. What if we could add control
to that also?

What would be the MINIMUM size dish needed?
( I could only put up a max size of ten foot dish )
S/N ratios?
Aiming factor?
decoding and sending telemetry?

I am NOT proposing anything on the scale of the SETI Projects Very
Large Array idea, but if done properly, we could help by extending the
life expectancy of some missions by two, three, or even four fold and
take some load off the NASA Deep Space Network.

This could also generate some credibility for AMSAT and maybe a little
income to finance a few satellites. This would be a good way to utilize
Amateur stations that are at Science and Hands On Museums also.

The Spartan Packet Radio Experiment (SPRE) which went up on STS-72 back
in January, 1996 proved that we could control and receive telemetry from
a spacecraft remotely via the internet even on Amateur frequencies. We
could do the same with this. The telemetry could then be distributed via
internet and decoded like the s...@home project using BOINC or something
else.

AMSAT as a group HAS the knowledge, expertise, and resources to pull
this off. Why hasn't this been considered?

My interpretations of the AMSAT by-laws:

THIRD: Said corporation is organized exclusively for SCIENTIFIC
purposes, including, for such purposes, the making of distributions to
organizations that qualify as exempt organizations under Section
501(c)(3) of the Internal Revenue Code of 1954, as amended (or the
corresponding provision of any future United States Internal Revenue
Law).

The SCIENTIFIC purposes for which said corporation is organized shall be
the carrying on of SCIENTIFIC research in the public interest by the
means of:

B. Encouraging development of skills and the advancement of specialized
knowledge in the art and practice of amateur radio communications and
SPACE SCIENCE.

C. Fostering international goodwill and cooperation through JOINT
experimentation and study, and through the wide participation in these
activities on a noncommercial basis by radio amateurs of the world.

AMSAT-NA is NOT limited to just amateur radio by the by-laws.

Just a little out loud thinking here. If this has been proposed and
rejected before, please excuse the bandwidth wasted here.

Hi All,

The title of this post paints an inaccurate picture
of this joint ESA/NASA mission.  Ulysses power
supply (RTG) is not producing enough power
anymore to run its instruments and heaters to
keep its propellant from freezing.  Ulysses was
due to be retired last year, but controllers devised
a clever method of firing its thrusters every 2 hours
to keep things warm.  The tanks are virtually empty
now.  Also its X-band transmitter failed leaving only
it S-band transmitter running at 512 bps.

Ulysses is currently 5 AU from earth with a 45 min.
1-way light time..to far away to act as an amateur
communication satellite in its decommissioned after
live, but it's an interesting mental exercise.

See the follow for more:

Think about it  If you had a multi mega dollar project, that your
livelihood and career were resting upon and someone came along and wanted to
add un-needed complexity and additional equipment that may or may not
interfere with your primary mission, how anxious would you be to share the
ride?  How many bad days have you had that started with someone telling you
that what they were going to do would have no impact on you? And then later
it did?

About the only thing we could do is use them as training guides for
receiving weak signals.  Satellities are not designed to qsy, or do anything
other than they actual function(s), specified long before they were ever
built.  Add more to a bird increases complexity, and also failures.

I'll bet they turned it off to free up that frequency for something else.
If that is the case then we can't even really try monitoring.

I've often wondered about the ham community using old systems but except for
really rare cases, they are just too specific to do anything for us.
