MO-76 (50dollarsat) was licensed by the FCC and had to submit a debri
mitigation plan. 50dollarsat was approximately 2" x 2" x 3" and most
certainly is being tracked by radar without retro reflectors. You can find
all about 50dollarsat at 50dollarsat.info with links to schematics,
pictures and descriptions. One of the things that reduces the time in orbit
is the very low mass of 210 grams. That in addition to Kapton sail brakes on
the antenna's to increase drag made the deorbit prediction to be less than
10 years. The "too small" argument does not seem to hold water in my
opinion. However, that doesn't mean they should have violated the law.

Subject: Re: [amsat-bb] FCC and Satellite Size
I've been following this as well.....and am confused about one or two
things...maybe someone can enlighten me?
This article has links to the actual exchanges between the company and
the FCC for folks that are interested in the 'source material':

Seems the problem was that they were too small (0.25U) for the ground
based space situational awareness tracking network to reliably track
them for the purpose of collision avoidance and prediction for other
spacecraft operators. They mentioned the addition of retro-reflectors
to aid in ground based tracking by increasing their radar cross section,
but FCC said this wasn't good enough. That was the grounds for
rejection from the FCC, too small to be tracked.
To be clear, the ACTUAL problem was that despite the fact the FCC turned
them down, it appears they worked the system to launch anyway, same ride
as AO-92 (so roughly the same orbit, though obviously there has been
separation over time)! Not good.
So putting aside the apparent disregard for the FCC...........why did
they get rejected in the first place? FCC said they were too
small....but............
I'm pretty sure the 0.25U form factor is something that Bob Twiggs (of
cubesat specification fame, as well as had a hand in MO-76) is pushing.
I forget the name they came up with for the 0.25U form factor, but they
had a new one (different I think than pocketQub form factor, like
MO-76). How then did MO-76 (aka Eagle-2, aka $50Sat) get up? It is a
'pocket cube' sized spacecraft (roughly maybe 1/3 the size of a 1U
cubesat). Also, how did KickSat get approval with all of its little
roughly 1" by 1" deployable 'Sprites?' I'm pretty sure both MO-76 and
Kicksat were approved by the FCC. Kicksat never deployed its Sprites so
no 'tracking data' for that, but MO-76 had reliable TLEs throughout its
life (and still does, most recent TLE epoch from a day or two ago on
celestrak). Also, if they are too small to reliably track, then how are
their TLEs getting updated reliably (their called SpaceBEEs for those
interested, index like APRS SSID, so SpaceBEE-1, SpaceBEE-2, etc. and
their are four of them total)? Satflare and N2YO are showing them
(though couldn't find them on Celestrak....).
Did the Amateur Radio nature of MO-76 and Kicksat factor into their
approval decision (the SpaceBEEs were an experimental filing and not in
the Amateur Satellite Service)? Maybe that was the trick? Amateur
Radio Licensing is more of a notification process to the FCC (and
coordination with IARU), where as the Swarm Technology folks were
straight up applying for a new license under experimental rules? Both
routes have to submit information according to what Paul mentioned, but
since the other two were 'already licensed' there was nothing for the
FCC to actually 'grant' ? (this is pure speculation, but I still
wonder....)
Finally, Kicksat was deployed from ISS and the 'mothership' was a 3U
(certainly trackable). Maybe since the sprite deployment was planned
for after the deployment from the ISS at lower altitudes they didn't
really care about tracking since they were going to burn up in a
relatively short time anyway. Also, the 'cloud of sprites' deployed
from kicksat would have been all around the 3U, so maybe that was
sufficient for tracking purposes? Still doesn't answer the MO-76
question though........
Interesting topic to see how this plays out........Already relevant to
this group with respect to MO-76, and potentially relevant for future
AMSAT missions if launch costs can be further reduced below a 1U form
factor.......
I ask because we are interested in the smaller form factor stuff here at
VT, so this is pretty important if the minimum size is dictated by
regulation and not technology. Seems to me that there is a 'gray area'
in terms of what can and can't be tracked (maybe intentional to not
reveal too much of the SSA capability?). From a regulatory perspective
maybe MO-76 and KickSat 'slipped through' because they were older
launches and the FCC wasn't prepared for something that small and has
since changed its process to include asking the SSA folks before approving?

I was under the impression that they had sent up a second one that worked

Paul,
Having "Linear SAT Activity Days" is a GREAT idea!
Maybe an AMSAT "Linear SAT 100" Award for 100 Q's
would be interesting. Perhaps, endorsable, too.

I admit that the launches of AO-91 and 92 have reduced my linear
operating time. As much as I enjoy operating on the linear sats,
operating portable as I do, I'm not going to be able to operate every
pass. I have made fewer than two dozen linear sat QSOs this year.
Perhaps some linear satellite operating days are in order where
everyone decides to work as many passes of the XWs as possible or
CAS-4B or UKube-1 or something. FO-29 and AO-7 do seem to draw a
decent amount of activity still.

They sent up a second one and claim that it worked, but there's no
independent verification despite many hams around the world listening
for it.
Also, there is still no entry in the Space-Track catalog for DSTAR ONE
Phoenix, just four unidentified objects from that launch. That
suggests that there are no signals for them to identify which object
they are and claim it.

At least part of the problem is that all-mode VHF/UHF equipment is
expensive. The FM satellites are busy because you can work them with an
HT. The linear birds are empty because you need to spend a month's (or
more) wages to get on.

Its not too many satellites, not enough ops!

Hello from Seattle
I read the bb almost thoroughly throughout the day. A small common
denominator is subtly appearing. I read, "I was on the bird all alone",
or something like, "no one to talk to".

I agree 100%, Scott. Unfortunately, I'll bet that fixing their ham radio
is a pretty low priority for NASA and the astronauts.

launched later this year. Can anyone give us all an update on the progress?
