What are the top barriers to revisiting highly elliptical and AO-40 type

goals?
Actually, from my perspective right now the top barrier is orbital
debris regulations.? GOLF-1 isn't going where I wanted to go because the enforcement has become stringent and a hot topic worldwide.? We can't
license or launch anything that doesn't de-orbit within 25 years and a
HEO orbit (GTO actually, keeping it simple for this point) is likely to
last "too long" by itself.? There are options available for deorbit BUT
the kicker right now is that they have to be proven and approved by the
FCC.? In that we know of no such device(s) available at this time,
keeping within the current expectations of 3U.? A change in size (6U)
might yield some possibilities but I know of none there either, right
now.? We have been discussing and working with both NASA and FCC for possibilities.? If something is available whether drag or propulsion,
then we get into the cost issue not to mention the price of a launch to
a GTO which is currently around $900k MSRP.? If we had a million bucks
and approved device(s) were available right now that fit within a $1
million budget then we would be pursuing that.

Another option is to find a launch with a low enough perigee to
naturally decay in 25 years, but whether earning an ELaNa launch or
buying one, we will always be secondary payload and don't have a lot of
say in specific orbit parameters.

One more option is rideshare, and that is also in active discussion.?
The point there would be that the onus of orbital debris compliance is
on the satellite we hitch a ride with, although that also goes into not
having a lot of say on the final orbit not to mention satisfying a
primary payload that everything will be just fine if they take us
along.? And then again, there's likely cost there too...? We have some
options that wouldn't necessarily require lots of money, they just won't
be happening today.?

Other possibilities?? As far as I know we are pursuing the current
options available per NASA and FCC, but that doesn't mean that there
aren't other possibilities.? If you have any, keep in mind that building
a good case for use of whatever the possibility might be is key to
gaining any approval.? And 90% probability that whatever will get you
back in less than 25 years is a tough challenge.?

We are bucking a trend, general CubeSat missions are happy with going
lower or from ISS, and bucking the trend not new with AMSAT but it is
new in this world today because of the regulation and stakes as well as
the fact that most everyone we deal with has no knowledge of AMSAT
beyond the record the we have created and grown in the last 4 years of launches.? We are not magically known just because we launched some
pretty cool satellites in the past.? Hopefully we will be known by more
through our continued contact, cooperation, and "by the book" production
and delivery of CubeSats with NASA, FCC, launch integrators, and others
who we look to for these launch opportunities.

Or get a bunch of money because that probably is the second biggest
barrier...

This resonates with me, as I see a general decline in the ability of
newly minted engineers coming out of our "higher education"
institutions. Too many distractions have made the average youngster impatient, sloppy, and poorly focused.

I'm not commenting either way on this observation, but it did make me
think of another consideration in the return to HEO or for that matter,
non-LEO and anything with a hefty price tag.? There has been a fair
amount of outcry over not so much the failure of AO-95's receive
capability and yes we are still working on possibilities to help
determine what went wrong or perhaps, get it working (I'm an optimist)
but take that to the level of a $1M or more project and the scrutiny
probably becomes pretty hard to bear, as you can imagine.?

Given the money to do a HEO it is also necessary to exercise the caution
and care to make sure you succeed, lest a mistake cripple the satellite
and run off half the membership kind of like AO-40's unfortunate tale,
not to mention running off investors.? That takes a bunch of time and
dedicated volunteers who have the expertise and stick around long enough
to make it work and pass along the knowledge.? To my knowledge, all of
the prior HEO took a lot of time, money, and effort.? I would be happy
to be involved with such a well subsidized effort but I honestly don't
see it happening quickly in terms of member-years, although 5 or
possibly more years in the "construction" business is nothing and no
matter how many years, is always amazingly short.

Just sayin', return to HEO is as much my desire as anyone else and I
still have my AO-10/13/40 antennas so I have every incentive to
succeed!? (That's partially a joke, son.)
It just may not be fast, it has to be careful, and it sure has to be a
mission set in solid requirements from the get-go and free of politics
or personal desires to change the course once the requirements are
written and design begins.? And with volunteers, that's not always as
easy as you might think, especially because they come and go.?
Volunteers are in my experience, less inclined to stay around the longer
times needed for things like this, at least 'these days'.? Look at how
many worked long and hard at AMSAT's prior HEO and projects.? And these satellite things, they will frustrate and contradict you every step of
the way.? It's almost like they resist being easy, perfect.? They are
the embodiment of Capt. Edward A. Murphy's law.? Ya gotta love it!

By the way, if you send a message from any client (YAAC, APRSIS32 or a D72 radio) to ISS with anything for text, you will receive the next pass predictions.

Hi Ken,

APRS client for windows is easily APRSIS32 by Lynn KJ4ERJ (http://aprsisce.wikidot.com/ ) Very much current and actively
maintained. It also includes satellite pass predictions via APRS
(keeping this satellite-relevant).

APRS client for Raspberry Pi: My preference here is YAAC by Andrew
KA2DDO (https://www.ka2ddo.org/ka2ddo/YAAC.html). If you don't need a
user interface (i.e. just for beacons, digipeating, and iGating),
Direwolf is a very good choice all by itself. I run them together, with Direwolf just handling the KISS TNC functions, and YAAC doing the
Graphical interface.

Android: APRSdroid gets my vote, though there are others.

Hello everyone,

I'm seeking suggestions for good APRS client software packages for
Windows? There are a number of ancient packages out there but it would
be nice to find one that's thoroughly modern and still being maintained.

I'm also looking for an APRS client for the Raspberry Pi and maybe
Android down the road.

What's your favourite?

Thanks & 73, Ken VA7KBM
