Hans,
Sorry about that. It's a bug in the code that only manifests itself on some versions of Linux. I had to fix the same bug in FoxTelem recently. I'll need to make a new build available.

Hello all,
I downloaded the software (V0.21) from the G0KLA website, running it on Linux (Kubuntu 18.04 with Java version 0.64). Well, I'm trying to run it, because I get the following error message.....
java -jar PacSatGround.jar Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 at PacSatGround.main(PacSatGround.java:29)
On my laptop it runs fine, albeit it uses a slightly older Java version (0.59) on Debian Testing from 18.03 (Netrunner).
Question: is there a specific Java version that has to be used with V0.21 of the PacSat software, or is my system messed up and I need to do a fresh install?
Cheers,

Hi Chris,
I've been able to pull AX.25 frames from the satnogs .oggrecordings of
Falconsat-3 and I usually get more valid frames than satnogs shows on
the
webpage when using my brute force demodulator (my brute force
demodulator
was the topic of my Symposium paper). Can you contact me off the list and let's work out how to automate demodulating telemetry from the existing recordings (and new recordings
as
they get added) and get it into the telemetry server.

Hi Chris, we spoke at the symposium about sharing data..
The best way to pull data would be to periodically pull from the api
for
db.satnogs.org, however its not working at the moment[1]. I've got
some
free time this weekend, I'll see if I can get this fixed.
That said, we have been decoding the messages we have from falconsat-3 into our dashboard[2] going back to April. Its just running through a
message
decoder, no telemetry. It shouldn't be too hard to write a struct for
the
telemetry, and re-decode the frames so we can make use of the rest of
the
data.
I'll reach out directly once the API is fixed..

I'm not aware of that data or how to access it. If there is an

of
data and it includes the WE files then it might be useful to us.

That's great, Chris! Thanks for all the work on that project.
Regarding telemetry, does AMSAT access the data that is forwarded to SatNogs?
Ever since FalconSat-3 was turned over to the Amateur Community,
along
with I'm sure a lot of others, I have forwarded thousands of telemetry
packets
from FalconSat-3 to the SatNogs database using the DK3WN Telemetry Forwarder ( http://www.dk3wn.info/files/tlm_forwarder2.zip ).
Now, I don't know HOW to access data that is forwarded to SatNogs in
that
way, but a lot of data is aggregated there from many of the past & presently active satellites that have known decoders. I'm aware that Univ. Colorado / Boulder obtains data from the CSIM satellite that way; I would
imagine
others do as well.
Thanks again for what I'm sure was a huge job on the new software!

I've written a new Ground station for FalconSat-3. If you had an
initial
go
with WISP without success or if you have never tried to decode
FalconSat-3,
now is a good time to try. This requires much less setup than WISP.
And
don't be put off if you don't have a hardware TNC, this will work
with a
soundcard TNC. Or, if you didn't try to listen to FalconSat-3 because
you
don't have a station that can transmit commands to the spacecraft,
then
read on. We still need your help to decode telemetry.
In particular we would like to encourage people to download the
Telemetry
and forward it to an AMSAT telemetry server. Currently more
telemetry is
generated than we can download with AMSAT Operations ground stations. Receive only stations can contribute to that as well as stations
equipped
to transmit to FalconSat-3 and request files. You can see telemetry uploaded so far here: http://tlm.amsatfox.org/tlm/FalconSat-3
There are details about the spacecraft, how to install the software
and
how
it works in the manual available if you download the software or
online
here: http://www.g0kla.com/pacsat/pacsat_ground_manual.pdf
You can download the software at www.g0kla.com/pacsat/index.php. I
have
also written some blog posts and thoughts about the software for
anyone
interested. They are linked from the download page.
There is much to do here of course and most of it probably won't get
done.
I would call this a beta release. If you have suggestions or bug
fixes
please log them online at https://github.com/ac2cz/Falcon/issues or
send
me an email.
The software is open source. All the details are here: https://github.com/ac2cz/Falcon/ The telemetry processing and
display
leverages common code from FoxTelem in a library here: https://github.com/ac2cz/libTelem/
