Hi,
Unfortunately my previous message did not make it through the BB
because it was down.
As expected, ARISSat 1 has now decayed. According to the first
"Final Report" of USSTRATCOM their last decay prediction was at
07:00 UTC +/- 3 hours on January 4, 2012, during an ascending
pass in orbit 2411 when the satellite was near 12.7 S, 354.3 E.
The latest report from Aerospace shows their decay prediction
at 07:40 UTC ? 100 minutes on January 4, 2012.
Since USSTRATCOM usually issues two or three "Final Reports",
we have to wait for the real final verdict.
73,

Chris,
Like you, I really enjoyed the old digital birds. However, the interest in
that has fallen off. AO-51 did have a very nice system, and a few other
satellites have had more traditional Packet BBS capabilities. The interest
just does not seem to be there, when the old satellites died, there were not
replaced.
73s,

Subject: [amsat-bb] What Happened to the PacSats?
About 12 years ago, I was really into amateur radio satellites (the
analog birds). I always wanted to try the PacSats, but I was a
college student, and could not afford all of the necessary hardware.
I tried to do it in software (and ended up falling in love with
Linux). Now I have a good source of income, and was looking into
dabbling in the PacSats, but looking at the Amsat website, it looks
like none of the old birds are up. So are there any plans to restore
store and forward messaging capability in future ham radio birds? Is
this currently still possible and I am just missing something?
Thanks,
Chris Maness

FUNcube -1 ? Launch details and time frame finalised
An agreement has now been reached with ISIS Launch Services BV, who are
based in Delft in the Netherlands, for them to provide a launch of the
FUNcube-1 CubeSat.
It is anticipated that FUNcube-1, which has been created by a team of
volunteer radio amateurs and other specialists over the past two years, will
be launched with a number of other spacecraft from a DNEPR rocket sometime
in the third quarter of 2012. The flight is planned to take place from the
Yasny launch facility which is in southern Russia near to the Kazakhstan
border. The spacecraft needs to be completed by the end of July 2012, ready
for shipping from the Netherlands to Russia.
The orbit is still to be defined precisely but it is expected to be nearly
circular and approximately sun synchronous. This will ensure that the
spacecraft has the necessary solar illumination and that it will appear at
regular times for educational outreach activities at schools and colleges.
The FUNcube-1 spacecraft will transmit signals that can be easily received
directly by schools and colleges for educational outreach purposes. This
telemetry will give details of the spacecraft?s health ? battery voltages
and temperatures and from this it will be possible to determine its spin
rate and attitude by plotting simple graphs. Additionally, experimental data
and messages can be displayed in an attractive format and provide
stimulation and encouragement for students to become interested in Science,
Technology, Engineering and Mathematics (STEM) subjects in a unique way.
The target audience for this project is students at both primary and
secondary levels and a simple and cheap ?ground station? ? actually it looks
just like a USB dongle, for schools to use, has already been developed.
In addition to providing educational outreach for schools and colleges
around the world, the spacecraft will also provide a U/V linear transponder
for radio amateurs during local ?night?, at weekends and during holiday
periods
The production and testing of the spacecraft itself has already been funded
via a legacy and other sources. It will however really help the project if
radio amateurs and other interested supporters could contribute something
towards the cost of the actual launch itself. With this in mind a special
donation scheme has been setup using the Virgin Giving charity donation
website http://tinyurl.com/funcubegiving/
All donations of ?25 (or equivalent) or more will be specially acknowledged
by the spacecraft itself ? exact details will follow shortly!
All donations received from UK tax payers can be ?Gift Aided? which will add
20% to the value of your donation.
More information about this exciting project will be made available over the
coming months at the website http://www.funcube.org.uk/

As an avid Hamsat operator with limited equipment I was able to listen and
record a pass
of arissat-1 two days ago. My goal was to make a memento of sorts for my
log of new
acheivements for 2012. I thought some readers might like to see it.

Hi Chris,
The golden days of the Pacsat Store/forward operations appear to be
gone for now, if not for good...I am still addicted, and wish everyday
for a rebirth...
The old pacsat birds are up there, just not functional. For a while a
few years ago, we had AO-16 running in voice mode (FM up, side band
down)! That was fun. But it only works when the bird is warm from
full sunlight--which won't occur for like 10 more years...sigh.
LO-19 emits a very low level carrier (most can't see it, or deny it's
there...but it is ;) )
WO-18 is like AO-16--transmitter won't stay on.
IO-26 is stuck in bootloader mode, emitting bursts of telemetry from
time to time.
Now, the GOOD news--read about Delphi3C and ISIS. There is some
digital downloading/telemetry that will be available perhaps by the
end of the year on a few new birds. Then, add Fucube-1 and -2, and
there will be more digital telemetry to collect.
But the Pacsat BBS operations as you remember them don't exist now.
But there IS a lot of telemetry to be collected. The good news is
that many of these will be using software based modems, available free
of charge!
