+- Implementation of the Galileo Open Service Navigation Message Authentication
+  (OSNMA), a data authentication function for the Galileo Open Service worldwide
+  users, freely accessible to all. OSNMA provides receivers with the assurance
+  that the received Galileo navigation message is coming from the system itself

+  configuration defines Galileo E1 OS channels. More details can be found in
+  [Introducing GNSS Navigation Message Authentication](https://gnss-sdr.org/osnma).

 ### Improvements in Usability:
 
 - Tidy up the `conf/` folder.
+- Add `install` and `uninstall` targets to the `nav_msg_listener` utility.
