IMOTUS-S SYSTEM FOR VESSEL SIGNATURE MEASUREMENTS In 2022, Cellula Robotics began a program to build and test the prototype underwater drone, Imotus-S, for acoustic and magnetic ship signature measurements. The Imotus-S system builds on Cellula's existing commercial Imotus AUV and is configured with The testing program focused on the ability to deploy a system from a marine vessel to provide signature measurements in open water. This capability would enable deployed vessels to easily monitor their signature in a timely manner, increasing safety and reducing transit requirements. The project included the Imotus-S manufacture and testing in local waters, followed by testing in Saanich inlet with an Orca class vessel in December 2022.
