A spatial reference beyond GNSS.

TerraNav™ is a Bravo1Alpha product for drones and effectors operating when satellite positioning is unavailable. The software combines 3D terrain navigation, flight path programming and optical object avoidance.

Tested at speeds of up to 500 km/h and an altitude of 40 m, TerraNav brings terrain, route and object awareness into one navigation environment.

What does terrain referenced navigation mean?

Terrain-referenced navigation uses the geometry of the landscape as a positional reference. TerraNav uses a 3D terrain model to support navigation when GNSS is unavailable.

What performance has been tested?

TerraNav has been tested at flight speeds of up to 500 km/h and a flight altitude of 40 m. These figures represent tested system performance.

How do flight path programming and object avoidance fit together?

Flight path programming defines the waypoint sequence in the 3D terrain environment. Optical object awareness supports obstacle avoidance as the aircraft follows the route.

What can I explore in this website?

The interactive demonstration shows terrain reference, waypoint navigation and optical object avoidance. Select a platform, rotate the terrain or pause the sequence to inspect the scene.
