Unmanned Ground Vehicle (UGV)

Building on technology heritage from planetary rover applications, NGC has developed autonomous navigation and mapping technologies for Unmanned Ground Vehicles (UGV) to be operated in challenging environments.

Unmanned Ground Vehicles (UGV) are more and more used in challenging, unsafe, uncertain and remotely accessible environments. Under these conditions, the interaction with an operator becomes difficult or not possible.

The level of autonomy to be implemented on-board such unmanned systems therefore needs to be augmented with advanced GNC solutions.

Advanced GNC solutions include visual navigation in GPS-denied environments as well as autonomous navigation and mapping in unknown environments through sensor fusion (Lidar, camera, IMU, GPS, etc.).

Such solutions developed originally for planetary rovers are fully applicable to unmanned ground systems.
