The "Polaric Server" is mainly a web based service to present APRS tracking information on maps and where the information is updated in real-time. It is originally targeted for use by radio amateurs in voluntary search and rescue service in Norway. It consists of a web application and a server program (APRS daemon).

The APRS daemon gets data from a TNC or APRS-IS or a combination. Users can present and manipulate the information through a HTTP service (REST API) and updates is streamed through a Websocket. The daemon can also be set up as an igate (internet gateway) and can be installed and run independently of the web app. It has its own webserver.

Polaric-aprsd is meant to be used as a backend-server for polaric-webapp2.

http://aprs.no runs a recent version of this software. More documentation on the project can be found here: http://aprs.no/polaricserver or https://polaricserver.readthedocs.io

We provide deb (Debian/Ubuntu..) packages. For information on getting started on a Debian based platform please see: https://polaricserver.readthedocs.io/en/latest/gettingstarted.html

From version 4.0, Polaric APRSD uses systemd for service management. See docs/systemd-migration.md for migration details and usage instructions.

To configure a server, use the webapp2. Some command-line scripts are also available: polaric-setcall, polaric-password, etc.

For first-time login use account: username=admin, password=polaric. Remember to change the password at your fist convenience.

You can always compile the sources to a jar file using the 'build.sh' script, on a Linux system a deb package can be generated by using: 'debuild -uc -us -b'

You will need JDK (OpenJDK) version 17 or later. Maven is used for the build process.

From version 4.0 we use Javalin for the webserver-part and a webserver-framework is factored out in a separate software-component: polaric-core. This is built separately but is just a 'mvn install'. The polaric-core is also available from Maven Central.
