The “Polaric Server” is an advanced open-source web-based service to present tracking information (APRS or AIS) on maps and where the information is updated in real- time. It was originally targeted for use by radio amateurs in voluntary search and rescue service in Norway.
Some important features are:
Technically, it consists of a client web application (based on OpenLayers) and a server program (APRS daemon). The APRS daemon (aprsd) gets data from multiple sources, typically a TNC or APRS-IS. It can present and manipulate the information through a HTTP service. The APRS daemon can be installed independently of the web app.
Some of its use is discussed in this book chapter from 2018 and ISCRAM 2015 paper and ISCRAM 2021 paper.
Don't forget to take a look at some screenshots .
Polaric Server is free software. See GNU General Public License v.2 and GNU AGPL v.3) Some parts of the source code may use compatible licenses like BSD. Copyright is owned by the respective authors of the software. We also encourage crediting the radio amateur (HAM) community and the Norwegian Radio Relay League for deveopment of APRS technology. If used for a publicly available online service and you make improvements or additions we encourage you to publish these improvements as open source. “APRS” is a registered trademark of Bob Bruninga.
Polaric Server (aprsd) runs on a fairly standard JVM platform and the client (webapp2) runs on a fairly standard Apache platform. Packages are available to allow easy installation on Debian based Linux distributions (Debian, Ubuntu, etc..). Debian 'Buster' or later is recommended. Raspbian (Raspberry PI) work quite well! Windows with Linux subsystem (With Debian or Ubuntu) should probably work. Though we support the Linux platform, it is probably not hard to port it to other Unix or Windows platforms.
Contributions to this project are welcome! Current version (running on aprs.no) is 2.11. Source code is available. The aprsd is written in Java and Scala. The Webapp is written in Javascript, HTML and PHP.
This application has a great potential but it is limited what very few people can do (without burning out). So if you find this interesting and want the project to grow, please consider helping the project or supporting it in any way. Software development, testing, user feedback, etc… All help is appreciated.
