How Does WXStar Work?

WXStar connects to your Starlink Mini and uses the satellite internet connection to download European weather data. It then broadcasts this data to your avionics using standard aviation protocols (FIS-B, GDL90).

Physical Connection to Starlink Mini

Starlink Mini alone

With WXStar attached

WXStar slots into the back of the Starlink Mini using existing slots — no fasteners needed. It uses the dead space below the Mini, so the cockpit footprint stays the same. Remove without tools by pulling upwards.

Power Connection

The WXStar replicates the exact same power socket you find on the Starlink Mini. Whatever cable you have been using to power your Starlink Mini simply transfers to power both the WXStar and the Starlink Mini at the same time.

Important: The Starlink Mini claims to support up to 48V. This exceeds the WXStar specification and could cause damage. Always verify your Starlink Mini power supply voltage before making any connections.

Network Connection

The WXStar connects to the Starlink Mini via wired Ethernet only. There is no WiFi connection directly from the WXStar device.

This is intentional: any custom WiFi is often a source of issues, so this wired connection is very robust. The Ethernet cable allows the WXStar to communicate with the Starlink Mini, its local WiFi network, and the Internet.

User Interface

A browser-based UI shows diagnostics and allows simulating a GPS position or generating FIS-B test images. The goal is that most users never need it — normally it is just power-up and forget.
