Re: [amsat-bb] Elections HEO QO-100' Linear NB + Digital WB
Yes, we once had a deal with Intelsat until it fell through. More recently we had a deal with the US Air Force and one of its contractors, until that also fell through. The reason we don't have a western hemisphere transponder in GEO is not because the "old guard" wants to shoot it down, but because these types of deals are very difficult to pull off in a market driven economy such as the US satellite industry.
QO-100 was hosted on a satellite built for a royal government which is not responsible to stockholders, a government in which an amateur radio operator held a high position of influence. A US based company would have to answer to Wall Street analysts to explain why they are giving away money that could have been paid out in stock dividends.
Changing the BOD membership will not alter any of these facts. It is not because we haven't asked the powers that be, and not because we are reluctant to "jump ahead of the project and grab what is needed". Space is Hard, and all the wishful thinking in the world is not going to change that.

I am intrigued about QO-100 and have monitored it here in Florida by remote WEB SDR access. I have not been active in the years since AO-40 failed and have been eager to see some HEO operations like I enjoyed from AO-10 and AO-13. Listening to QO-100 has rekindled that interest.
Last month on AMSAT-BB I posed the question about getting a GEO ride share with a commercial satellite, something that was considered 12 years ago with Intelsat. Having a QO-100 type transponder here CONUS would grow the hobby and get folks like me active again (and contributing sums as I did for AO-40). However, the "old guard" shot my idea down for the usual reasons. (See my threads last month).
Having a QO-100 type transponder with a hybrid of narrow band linear side and wide band digital side would open up a lot of opportunities for operations, public service and experimentation.?? I hope the new "slate" of BOD will consider this type of project as a priority.
Personally, I think GOLF has not achieved results fast enough to getting us a larger footprint. I am not advocating scrapping of that effort, but sometimes you have to jump ahead of the project and grab what is needed.

Dan, I agree with you completely that the reality of the market is not going to change and we can't expect a hand out like QO-100 got. We can change how we pursue our goal in light of the existing conditions. To do that requires a change in leadership that is willing to make hard decisions that may not be popular at first but necessary in the long term.
At the 2014 Symposium, Jan King gave a inspiring talk about the ways to get to HEO which he followed up with a special meeting the following day with the AMSAT president. You were there Dan. This meeting layed out a proposal for a 6U cubesat in a GTO orbit. The meeting was attended by some of the most experienced engineering talent ever to be part of AMSAT. The pitch was made and rejected by the board. Many of these people are still on the board. The majority of that talent has left in frustration and six years later we are trying to catch up to where we were 20 years ago. It's the old definition of insanity, doing the same thing over and over and expecting different results.

Howie,
I believe your premise that the pitch was outright rejected by the Board is misleading. Although their proposal to submit for a CSLI launch in November 2014 was not adopted at the time, we have adopted the approach of returning to HEO through a CubeSat in GTO through the GOLF program. We have many talented engineers working on that project. I believe that work on that project has progressed to such a point where we can make a big push to execute this within the next few years. As a Director, I will push for an aggressive fundraising program to make this happen.
Unfortunately some have proposed canceling the GOLF program, including one Director who nominated you. This would be a disastrous mistake that would scuttle both our relationship with NASA and all the progress our excellent engineering team has made over the past three years.

No one has proposed cancelling GOLF.
Howie has been a board alternate over the past year, and knows that what you have said is not true.
We can afford to fully fund either the office and an employee, or fully fund GOLF, if and only if we save some significant money by digitizing the Journal. I presented a paper about this to the board in early spring.
Without any board meetings, there have been no proposals since the motions made in March about the bylaws committee (hasn’t met yet), formal support of AREx by AMSAT, and the PPP loan.
If there had been a proposal to cancel GOLF you better believe it would be in the minutes, and If it had come from me then I would have written an article about it for the Journal with a solid alternative replacement and a funding plan.
The board did indeed reject the proposal Howie is talking about. It disappointed a lot of people.

Dan,
Agree that the context are different but the only way to achieve same is to work hard on it and without begging (as it seems that we do no have the money for either HEO or GEO) no way we may succeed.
That said, there are some possibilities and if we try hard enough we may succeed, the real issues are that the community as a whole does really work hard enough and we are probably not passionate enough to put the birds up there? Yes difficult but not impossible, may be US laws is a deterrent but we are global and other jurisdiction may be used.
QO-100 has made us to think globally or at least half of it, this is we way forward for both financing and putting birds up there. It we direct our effort in that direction (a global vision) we have more chances to succeed. So rethinking the HAM satellite strategy globally instead of thinking regionally may work out.
Just my 1 cent input.

I, too, would love to see electric propulsion on one of AMSAT's birds. However, it is not as simple as "buy this off the shelf":
- Power: One must also consider the 40W required at nominal thrust. This has implications for generation (solar cell area/efficiency required), management (circuit board space & heat dissipation), and storage (battery).
- Physical integration: How big is it and how much does it weigh?
- Control: The algorithms to alter one's orbit in space are known, but much planning, coding, and testing is needed to make sure money isn't wasted by doing something that causes early de-orbit.
- Testing: Where does AMSAT obtain the testing facilities necessary to ensure proper operation, or even inclusion in the launch manifest, should the ride provider dictate it.
All of these problems are solvable with enough time, appropriate funding for all aspects of the project, and motivated, knowledgeable volunteers.
As for the basic cost of the the thruster: I'll chip in $100. We need only 489 more people, roughly, to do the same.
Who's with me?

As it happens, Applied Ion is reporting partial success with a thruster design today: https://twitter.com/Applied_Ion His cost per thruster is much closer to Zach's $100. Two thrusters of a previous design of his are scheduled to fly on the AMSAT-EA Genesis satellites, NET September. These are Open Source designs.
Thanks

slow, but it's a cost effective way to raise an orbit.

I, too, would love to see electric propulsion on one of AMSAT's birds. However, it is not as simple as "buy this off the shelf":
- Power: One must also consider the 40W required at nominal thrust. This
has implications for generation (solar cell area/efficiency required), management (circuit board space & heat dissipation), and storage (battery).
Physical integration: How big is it and how much does it weigh?
Control: The algorithms to alter one's orbit in space are known, but
much planning, coding, and testing is needed to make sure money isn't wasted by doing something that causes early de-orbit.
- Testing: Where does AMSAT obtain the testing facilities necessary to
ensure proper operation, or even inclusion in the launch manifest, should the ride provider dictate it.
