Install the satnogs_gr-satellites "addon" and use your station more!

I have a suggestion:

  • Rebuild the flowgraph to accept UDP input.
  • Use existing grsat_wrapper.sh to launch this for certain Norad ID, also for post processing.
  • Include in the addons for the dockerized -client
  • Absolutely NO sudo used, should not be needed if properly integrated

Making it work in docker is a little bit different than on a regular -client, but this should not be a problem.
The flowgraph itself didn’t look too hard, need to verify that the default flowgraph selects the correct samp_rate etc.

edit:
As the future of LRPT seems bleek at best, perhaps not worth putting too much work into this.
The main hurdle for now is the satnogs_fm flowgraph does not use the baud setting so will not have high enough sample rate. If it was changed to satnogs_fsk we could probably use the udp data out from that.

Is this add-on still necessary in new raspberry images?
I have to update to Bullseye with a new image (my station is not updated since years) and I don’t know if it’s included in satnogs images or I have to still again the addon …

Thanks and 73

Hi, this is not included by default in any official install, so you have to install it again.
In the docker work I have done for my collection of addons I have started work on deprecating the old bash-based integration in favor for a python version, but that is still in testing. It also has a companion imagedecode which is a framework for producing images directly from the demodulated data. Implementing more image decoders is a continuous work.

@SA2KNG I have a stupid question, why are there 2 different versions of gr-satellites?

The satnogs version satnogs_gr-satellites and the other version is gr-satellites. The satnogs version is (I think) 3.15.1 and the “stand alone” version is 5.6. Both github sites point to the same documentation.

Do they both decode the same satellites?

Just curious,

It isn’t a stupid question, the reason is as follows.

SatNOGS has a dependency with GNURadio 3.8 and there is a seperate gr-satellites release that can work with this GNURadio release.

The main/master release of gr-satellites works with GNURadio 3.10 (and this version can’t work with SatNOGS)

The releases and compatible GNU Radio versions are:
GNU Radio 3.10 → gr-satellites v5.6.0
GNU Radio 3.9 → gr-satellites v4.13.0
GNU Radio 3.8 → gr-satellites v3.20.0

Feature-wise, they should be pretty much the same, all the stuff is implemented in all three branches for now. Dani is considering dropping the 3.x soon thou, probably only us that keeps him working on that version still. Thankful that he still does btw (:

This is not gr-satellites, it’s a integration of it into satnogs-client.
