Welcome to Flarmradar

While the transmission protocol of the FLARM devices are proprietary (and unusable for our purpose), the ​Data Port Specification is public. The Flarm-Radar project uses the data available on the devices Data Port, just like any 3rd party product.

This wiki should become a source of knowledge for the Flarmradar-Project.

... still needs some writing :-)

Ground Station

The concept​ of the client is quite simple, as it acts similar as a regular 3rd party product. While these are mostly hardware devices, our client is a piece of software that reads the Data Port from any regular FLARM device (RS232) and streams the data (via the HTTP protocol) to the Flarmradar Server. Since data streaming does not require much computing power, a mini-computer like the ​Raspberry PI is sufficient. This is a credit-card sized computer that is able to run a Linux operating system (Raspbian) at negligible cost (50$ or so). For standalone installations with a local Flarmradar-Server, the client can be installed alternatively on the same computer where the Flarmradar-Server is installed.

Follow our Construction Guide to build up a Flarmradar Ground Station. Our FAQ might also have answers to questions that come up while installing and launching a Flarmradar Ground Station.

While the Construction Guide shows the most convenient setup, more specialized configurations (WLAN, Battery powered stations, low-budget implementations, etc.) are also possible. But this is more for people that are not afraid of burning one's fingers when working with the soldering iron.
