JBalloonNav¶
JBalloonNav is a moving map and navigation app for balloon pilots on Android. It provides offline maps, airspace overlays, flight tracking, wind prediction, weather data, and tools for competition and recreational flying.
What Can It Do?¶
- Offline maps — download OpenStreetMap-based maps by country or region for use without mobile data
- Airspace display — overlay airspace boundaries from OpenAIP with category filtering and height limits
- Flight tracking — record your flight path with GPS, review statistics, export as GPX or CSV
- Predictive track — see where the wind will take you over the next 15 minutes (configurable)
- Wind history — capture and review wind speed and direction at each altitude during your flight
- Trajectory forecasts — multi-level wind path predictions using Open-Meteo weather models
- Weather / METAR — view current airport weather conditions and surface data
- QNH & barometric altitude — use the device barometer for pressure-altitude with QNH correction
- Waypoints — add, edit, import/export waypoints in GPX format for competition or navigation
- User-defined areas — draw circles and polygons for competition zones, sensitive areas, or personal landmarks
- Country-specific areas — BBAC Sensitive Areas (UK) and Bavarian Nature Areas (Germany)
