Successful trials were recently conducted off the coast of La Ciotat (South of France), deploying two uncrewed platforms: iXblue DriX Uncrewed Surface Vehicle (USV) and Teledyne Gavia Autonomous Underwater Vehicle (AUV). Both uncrewed platforms were remotely controlled and supervised from iXblue Onshore Control Center, with iXblue DriX USV acting as a communication gateway between the onshore control center and the Gavia AUV. The two drones were able to successfully communicate together, thanks to the Gaps USBL positioning system installed within the DriX gondola, and that tracked the Gavia AUV.
