ORI Transponder Design Review 30 July 2020
Greetings all!
A design review workshop has been scheduled for 7am Pacific 30 July 2020 for the 6U digital multiplexing transponder from Open Research Institute. This work is made available for free to the general public and assumes AMSAT as the primary audience and beneficiary.
The design is the same as one in progress for AREx (AMSAT/ARISS USA). The design review will be of direct benefit to AREx and meets their requirements.
The design is under consideration for other missions.
If you would like to participate in the design review workshop, then please write me at w5nyv@arrl.net for a Zoom invite.
The communications functions and circuits are the focus of this review.

(Brief) Statement of Work for Phase 1 can be found here: https://openresearch.institute/wp-content/uploads/sites/10/2020/02/Summary-P...
Thank you! -Michelle W5NYV (One of your AMSAT Directors)
Update!
Thanks to Lou McFaddin, it will be on the AMSAT WebEx server so that more people can attend.
Will send out links next week.

Which existing product most closely match the completed P4XT functionality?
Are there any affordable modulators for Ham Radio ground stations?

Good question, thank you.
We did a survey of communications systems similar to this design for the Commodity Jurisdiction request. Most of those are substantially more expensive than our price target. Some provided much less functionality or had very restricted user interfaces.
Our 5GHz RF efforts focus on a design originally outlined by Mike Seguin N1JEZ, using Skywave parts, and prototyped by Julian KF4MOT. I'm sure he'd appreciate additional help.
There is a lot of useful feedback from recent work with the AREx team that will be incorporated and a variety of daughter cards we use in the lab.
The goal from a product point of view is to provide more than enough information for people to use existing SDRs and amplifiers, as well as providing a manufactured solution.

Michelle,
I am kind of surprised that AMSAT-BB is the first time I have heard about a design review that could impact the AREx design for the Lunar Gateway SDR. As I stated in the AREx meetings, I want to ensure we have a host of independent space experts that are pre-selected and vetted for all our design reviews. This has not been done yet. And it will be an essential element for AREx to move forward on our Lunar Gateway payload with the space agencies.
This design review has not been communicated to the AREx team. We absolutely need to have open and full team communication on all design developments to ensure AREx mission success. Not communication to AMSAT-BB, where only a small segment of the AREx team is a part of.
As the acting Program Manager for the AREx Lunar Gateway initiative, I would appreciate you letting us know ahead of time of any planning for design reviews as well as any planned meetings that can affect the AREx system design. If I remember correctly, I was expecting a plan from each team on their efforts to evolve their systems over the next several months. This is a critical first step. We also need to get a handle on who all is on this team so that we can ensure that there is open, effective and impactful communication across the team and the subsystems.
I would appreciate your attention on this matter.
Thanks,

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?
