Android app that visualizes the aircraft traffic from The Open Glider Network project (OGN) on a map.

OGN can receive signals from gliders, tow planes, helicopters, etc.

This app is a flight radar for small aircraft with FLARM equipment.

The decoded signals can be used with apps like XCSoar on TCP port 4353.

Current version: 1.4.4

See release notes for details.

Download the app at https://play.google.com/store/apps/details?id=com.meisterschueler.ognviewer

Track aircraft with FLARM devices via the OGN and see OGN receivers on a map.

See flight paths of aircraft - track only (default) or with heights (multicolor option in settings).

Use APRS filter for filtering oder long click on the map to set a radius filter.

App can run in background and listen to OGN messages. Use exit function to save battery and data!

Other apps can connect on TCP port 4353 (must be activated in settings).

Manage known aircraft in "ManageIDs" activity or click long on the info window of an aircraft.
