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:

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!

Chris,
Thank you so much for this. I will admit to being a bit bewildered by WISP and I never
actually got it working. I look forward to giving this a try this weekend.

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..
Cheers,

Hi Chris,
I've been able to pull AX.25 frames from the satnogs .ogg recordings 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.

Hey Douglas,
I didn't write a demodulator. That's done by a TNC or hs soundmodem. Happy
to talk off list but I didn't code this part. It starts with kiss bytes and
then builds the directory, requests fills, supports uploads etc. As a by
product we get the telemetry and I decode and display that.

New subject: [amsat-bb] New Telemetry Decoder for FalconSat-3
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,
Hans

Hi Chris,
I've been able to pull AX.25 frames from the satnogs .ogg recordings 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.

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.

I fixed the issue. Download the new version at the usual place or directly
here:
http://www.g0kla.com/pacsat/PacSatGround_v0.22.zip
This just corrects the problem on some versions of Java. It also fixes
some issues with small fonts on high DPI displays. Let me know if there is
any issues with font sizes.
thanks

New subject: [amsat-bb] New Telemetry Decoder for FalconSat-3
For some reason mail from this list with the above subject from Chris is
not getting into my mailbox. Luckily I check the web based archive every
now and then.
Chris, thank you for updating the PacSat software and fixing the Java
problem. Version 0.22 is starting up without any problems now. I use UDP
streaming from GQRX into direwolf and the PacSat software can read the
KISS data via TCP on port 8001 then. Every time v0.22 is starting up it
still complains that I need to set up a virtual serial port, but the
ignoring the warning seems fine. It shows a 'decoder ready' message, so
I assume that means it's working.
Reading the manual now as I have no experience with PacSat. Waiting for
a good pass of Falconsat-3 tomorrow to see if I can get some data in.
Data out is for another day.
73 and cheers,
Hans

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,

Subscription settings: https://www.amsat.org/mailman/listinfo/amsat-bb Hi Chris,
I've been able to pull AX.25 frames from the satnogs .ogg
recordings 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.
73,
Douglas KA2UPW/5

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

On my laptop it runs fine, albeit it uses a slightly older Java

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?

New subject: [amsat-bb] New Telemetry Decoder for FalconSat-3
Chris,
thank for posting this and all your work.
I monitored an early morning pass at my location (around 2019-02-09
12:56) and noted good signal strength.
I am using a simple 70cm turnstile with mast mounted pre-amp, airspy
mini, and SDR#.
Also, using high speed HS soundmodem configured for G3RUH 9600 baud all
configured following the description in the pacsat ground manual document.
SDR# has audio filtering turned off as I do for use with the FOX sat
programs.
So far, no decodes.
So, my primary question as this point is - what mode should the radio
bet set to? NFM? WFM? USB? Bandwidth? I am currently set to 15kHz
bandwidth.
I automatically correct for doppler.
cheers, Graham ve3gtc

Graham,
The data is Frequency Shift Keying - FSK - so set the sdr to NFM. 15kHz
wide seems reasonable to start with.
You should see bytes decoded in hs_soundmodem. If that is working, but the
ground station is not decoding then make sure you have the TCP connection
setup correctly.

New subject: [amsat-bb] New Telemetry Decoder for FalconSat-3
thank you everyone for your suggestions.
I followed a couple more passes and it seems that I just don't have
sufficient signal level - enough to clearly see and track the signal
that would be good enough for the UK funcube signals but not enough for 9k6.
Other than that the decoding software and hs-soundmodem all work well
together.
I took a look at the passes I would see and I get only one per day where
the highest elevation gets as high as 17 degrees, the remainder are all
12 degrees or less.
I have a dual band vertical mounted at roof top level and I may give
that a try but unfortunately it doesn't have a mast head pre-amp but I
can put a pre-amp in line near the radio which may help.
too much snow on the ground and on the roof; it will be a couple of
months before I can get to any real antenna work.
cheers, Graham ve3gtc

Graham,
The data is Frequency Shift Keying - FSK - so set the sdr to NFM.
15kHz wide seems reasonable to start with.
You should see bytes decoded in hs_soundmodem. If that is working,
but the ground station is not decoding then make sure you have the TCP
connection setup correctly.
