New Telemetry Decoder for FalconSat-3
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/
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, -Corey KB9JHU

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.

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

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?

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

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.

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

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 .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..

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.

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.
