my answer to your mail from Oct. 16 has twice been returned by comcast.net. The

That subject may be a bit optimistic. Bob and Paul will be trying to stretch
the footprint. At the applicable passes between Scotland and Seattle. So when
Seattle comes into the footpint a little bit of room would be appreciated.
Remember, if this were easy, everyone would be doing it!.

Someone mentioned waaay back in this discussion something about ITAR and
international students being taught in the US. Read this article:

Wait... gah!!!
No matter the solution, would you mind posting to the -BB also, Erich?
I'm in the process of trying to finish an LVB and, if I run into the
same problem this might be a good place to start.

Of course we are. Satellites aren't launched on desire only.

find who had launches to over 800km. They had no secondary opportunities
available.

We have a unique opportunity with the Atlas 5/DMSP launch, as DMSP is
a relatively lighter spacecraft than many of those that fly on Atlas.
For that reason, we have a tremendous amount of performance margin.
That's certainly not the case for some future missions that Atlas will
be flying. So

So I have a pair of 14 dbi flat panel Wi-Fi antennas, complete with pigtail

I tried to be careful of the words I used.

Suitsat 2/ARISSsat is a linear transponder done with DSP. Its seems
perfectly reasonable to me to do transponder signal filtering and command
decoding digitally as it makes things smaller and lighter. You could also
make a better transponder by forming filters around the uplink signals so
Your math seems to be off. Eagle disappeared due to lack of money to pay for
a launch rather than technical problems. This is much better than paying for
hardware to sit on the ground. Suitsat 2 and ARRISsat are the same thing so
there has been no failure yet.AO-51 is in orbit and working.

Hi Bob (N4HY)
Thanks for taking the time to ponder for the BB and me some of the twists
and turns
of ITAR issues.
I hope the BB apprecaites your time and effort.
Here are a few more questions?
8.) How do exclusionary zones with in the US work as in the AO-40
integration and shipping
zone,
Do you think that they would agree to fly anything other than ballast? Have
you talked to the project manager? AMSAT has flown satellites using excess
space in the past because the launch agency agreed years in advance and the
satellites were built to fit in that space.
