Research presented at OCEANS’21 Conference

Some of the latest results on the design and testing of the control system for Platform for Expanding AUV exploRation to Longer ranges (PEARL), an integrated autonomous floating servicing station that utilizes renewable energy to simultaneously provide AUV battery recharging and data uplink via new generation high-bandwidth low-Earth orbit satellite constellations, were presented at the OCEANS’21 conference. The paper entitled ‘Autonomous Control of a Prototype Solar-powered Offshore AUV Servicing Platform’ is available for download at the conference website.
