Hmm. This is a bit of a brain teaser...
So if the satellite is deployed towards the rear of the ISS, it's velocity
will be slightly lower.
So does that mean it will go to a lower orbit- (Same as firing retros to
reenter)?
If so, then I believe as the orbit altitude is reduced, the apparent
velocity increases.....(??) which will cause ARISsat-1 to 'move ahead' of the
ISS over a few hours
But didn't we say the velocity would be less than the ISS due to the method
of deploying it against the velocity vector ?
Time for me to have a Tuna sandwich. We all know it's probably full of
Dolphin...and they are really clever.

Hi all
I am giving a demo to a middle school in Lafayette LA EM30 . It would
impress the students if you could come up on Echolink node 370324 at 10:20
CST Thursday and help demo to the 7th graders. If you can make it please
respond to this email.
Thanks

Hi!
Does anyone here have a good UHF preamp that is sitting in a corner
collecting dust that I could use on my Arrow or mobile satellite setup? I
would never run anymore than 25w through it ? I would be lucky if I did 10w.
I weatherproof model would be preferred, but not 100% necessary. I thought
I would check here before I go looking at all of the commercial retailers.

Mine is not for sale, but I can highly recommend the ARR 25 watt switched
preamps. Mine is about ten years old and has served me well under both
portable and fixed ops. The price is very reasonable as well.

Interesting puzzler, eh? From what I have read in the past, I think this
their logic.
What they are trying to do is to separate the orbits of the ISS and ARISSat
as quickly as possible, to avoid the potential for a collision. Consider
the options:
1. Throw it sideways to the ISS orbit. The result is that twice per orbit
the two spacecraft's paths will cross, side to side. Bad idea.
2. Throw it ahead of the ISS (faster orbit speed). This will raise the
orbit, slightly, and also make it a bit elliptical (up and down). The
higher orbit makes the satellite go behind the ISS, but the elliptical shape
also means that the orbits will cross every orbit (but out of phase, so they
won't be at the same place when they do). But, then as the ARISSat orbit
decays, they will get closer and closer, potentially getting back to the
same place. Not good, either.
3. Throw it behind the ISS (slower orbit). As you note, this will lower
the orbit (and make it a bit elliptical), and initially the apogee of the
orbit will intersect that of the ISS. Being in a lower orbit, ARISSat will
move ahead of the ISS, and over time, as the ARISSat orbit decays, the two
will diverge even farther. So, this is the safest.
At least, I think that's the logic. If not, pass me some of that tuna...

Thank you Greg.
Makes sense to me now. Also, just calculated the velocity of a 90 minute
LEO orbit and the velocity of a geostationary 24 hr orbit using
circumference and time. Found that the velocity at LEO is higher, so
presumably the
decrease in orbit altitude of Arissat due to decay must also add
acceleration. (Gravity)

Hello to the group:
Have been reading about the satellite and BPSK 1000,but then have a little
doubt on two subjects:
1- The BPSK 1000 part, can be decoded on FM, SSB or a combination of both?
2- In the same line, if one TX to it on U/V, what is the mode to use?
70cmUSB/2mLSB, 70cmLSB/2mUSB and/or 70SSB/2mFM?
Thanks in advance.

Few days ago, a link was posted here to the ARISSat subversion
repository. If you look around there you will find the source code for
the ARISSatTLM application (hint:
https://svn.sarpeidon.net/viewvc/suitsat2/ground_station_software/ARISSatTLM/
). You will also find the reference modem by Phil KA9Q called
"demod2". This package contains both DSP library and small command
line applications and the whole package can be compiled under linux as
is. The demo apps can use pipes for I/O so it is very easy to chain
them together to create a complete modem. There are even utilities to
add noise and CW message.

Isn't this the source directory for the groundstation component?
https://svn.sarpeidon.net/viewvc/suitsat2/ground_station_software/ARISSatTLM/
You may need to navigate up and down a bit.

Angel,
You will receive the beacon on SSB. You may recall the telemetry used on
satellites such as AO-10, AO-13, and AO-40. This is just an enhancement.
The only time you will be transmitting to ARISSat-1 is when the transponder
is active. It is a linear transponder, so the usual rules apply.

Subject: [sarex] ARISSat-1 Demodulation
Hello to the group:
Have been reading about the satellite and BPSK 1000,but then have a little
doubt on two subjects:
1- The BPSK 1000 part, can be decoded on FM, SSB or a combination of both?
2- In the same line, if one TX to it on U/V, what is the mode to use?
70cmUSB/2mLSB, 70cmLSB/2mUSB and/or 70SSB/2mFM?
Thanks in advance.

SSB, and most users will find that USB makes sense with Doppler
shift...it is downlink only, telemetry and experimental data.

70cmUSB/2mLSB, 70cmLSB/2mUSB and/or 70SSB/2mFM?
70cm LSB uplink, 2M USB downlink---only in the frequency range of the
transponder portion of the satellite, when it's active.
The FM part of the satellite is downlink only, carrying voice
telemetry and other messages of good will.
