GPS Navigator Features
Maps, routing, search, GNSS, marine charts all running locally on the device. No API key. No cloud round-trip. No signal required.
Offline route engine
Maps loaded · GNSS active · route ready
Navigation
Farun stores the full navigation stack locally map rendering, POI search, route calculation, elevation context, and isochrone visualisation. The device does not need an API key, a data connection, or a server anywhere in the chain to navigate.
Roads, terrain, water, buildings, land use, hardware-accelerated rendering at certain zoom levels from local storage.
On-device route calculation with step-by-step instructions, distance, and duration. Reroutes from current GNSS position when plans change.
Wide database of points of interest searchable entirely on-device - campsites, fuel, emergency services, marinas, trailheads, and more.
SRTM-based elevation data for gradient shading, contour lines, line-of-sight estimates, and terrain-aware route planning.
Visualise reachability from any point, show which areas are accessible within a given time or distance threshold.
Reorder waypoints for minimum total distance or time, essential for field teams and delivery runs with multiple stops.
Positioning
Dedicated satellite positioning gives the GPS Navigator its own independent location source. No mobile tower dependency, no network-assisted positioning fallback. Accurate in dead zones, open water, canyons, and high canopy.
GPS, GLONASS, and Galileo constellation support for sub-metre accuracy without network augmentation.
Real-time satellite count, fix quality, HDOP, and lock status visible on screen and queryable via the local device API.
Continuous heading, ground speed, and position updates at configurable intervals for navigation overlay and operational logging.
Position data stays on-device by default. No telemetry leaves the unit unless your deployment explicitly configures a sync or export.
Marine
Marine mode brings nautical chart layers, tidal predictions, water boundaries, and coastal POIs into the same rugged device with no mode switch required. The Navigator detects water entry via GNSS and transitions automatically.
ENC-derived chart data stored on-device. Depth contours, buoys, shipping lanes, restricted zones, and marina PoIs - no chart server required.
40-year tidal harmonic dataset covering coastal and inland waterways. Precise high/low tide times for any coastal waypoint, years into the future.
GNSS detects transition to open water and switches to nautical chart mode automatically. No manual toggle required.
Set and save waypoints, plan multi-leg passages, and calculate leg distances and bearings on the chart view.
Under the hood
The features above are designed for field teams, fleet operators, marine skippers, and expedition leaders who need navigation to be a reliable system, not an app that might fail at a critical moment.
Tile rendering, zoom, pan, search, and route overlay run entirely on the device. No tile server, no CDN, no buffering. The map is instant because it's local.
The routing engine recalculates from the current GNSS position in real time, whether you missed a turn, changed your destination, or the terrain made the original route impassable.
Trip history, route data, and position logs stay on-device by default. Nothing leaves the unit unless your deployment explicitly configures a sync or data export.
Every device in a fleet runs identically same map data, same routing profiles, same POI database. Consistent navigation behaviour across the whole operation.
When you enter the coastal waters, you just change the routing mode to marine mode. The device then switches to nautical chart mode and loads the relevant chart data.
Map tiles render through the device's GPU pipeline, not software rasterisation. This keeps the interface responsive at any zoom level, even with high-density vector datasets loaded.
Honest limitations
Real-time traffic conditions require an internet connection and are not available offline. Route calculations use static road graph data.
Maps are pre-loaded at procurement. Road graph changes and new POIs are delivered via optional annual update bundles, not live.
Turn-by-turn routing is visual. Audio navigation prompts are not available in V1.0 and are planned for a future firmware update.
