Good morning Mineo, 
Finally with some help I was able to get it running. 
There are requirements and dependencies that need to be in place. 

First: It needs python2 as the default and not 3 as it is in Ubuntu 18
as far as I know. 

user@locutus:~$ python --version
Python 2.7.17 

My suggestion is to start the FloripaSat app from the command line and
see what kind of errors you get and go from there 

user@locutus:~$ which floripasat-grs

On my system it also needed a GNURadio 3.7 environment to get it running
but others where successful with 3.8 

It is possible but not very clear. 

More information can also be found at:

Let me know if you need more information, good luck.

Good Morning Mineo,

Yes, we developed a custom-made software called "FloripaSat GRS".
You can see the details and download it in this page

We are updating and solving some issues of the decoding process,
apparently some packages of data are not decoding in the correct way.
if you run in any problems please let us know by creating a new issue
in this page http://github.com/floripasat/grs/issues

Thank you for been part of the FloripaSat-1 mission.
