Aquagrid consists of GNSS enabled buoys deployed on the surface, streaming their position to an underwater AUV.

This allows the AUV to determine its position relative to the buoys, as well as estimate all parameters needed for autonomous navigation.

It's primary advantages are listed below

• Faster deployment compared to LBL

• Cheaper than LBL with the same accuracy

• Underwater units can be equipped with a MEMs based IMU suite, significantly reducing cost and size

• The aquagrid network can be used for positioning as well as C3
