[amsat-bb] ORI Transponder Design Review 30 July 2020

[Michelle Thompson]

I apologize for the misunderstanding. Entirely my fault.

There was very strong support for the architecture at the ARISS hardware
summit last month. This workshop review is intended to honor that approval
and support, and pay it back with interest, not to upset it in any way.

Reviewing the systems architecture (to be ready for a PDR originally
scheduled for August) was discussed in a recent call, along with
recruitment from wider communities. This seemed to get a green light.

A review was discussed in the systems engineering splinter group with
strong support.

I have complied with a request to get the right communications support (GTM
vs Zoom), which is greatly appreciated feedback.

Having a workshop review was not perceived as controversial during that
conversation, or I would have not proceeded.

With schedule and staffing identified at the highest risk level (severely
high!) I’m very motivated to reduce that risk for you, however I can. The
more people that review everything we have for architecture, as soon as
possible, the better.

The impact is intended to be more and better choices for widest possible
use, as soon as possible, no strings attached. The only people restricted
are those that implement any provisional design. All know it is subject to
change and high risk.

What things would you like me to do in order to satisfy all your concerns?
