Integer Technologies has successfully completed at-sea testing of its UUV digital twin prototype, a DARPA SBIR Phase 2 project, aiming to improve undersea communication and decision-making for UUV missions.
The at-sea testing is part of its SBIR Phase 2 Award, Defining and Leveraging Digital Twins in Autonomous Undersea Operations, with DARPA.
Integer, along with its subcontractors at the Woods Hole Oceanographic Institution and Rite-Solutions, have been investigating the implementation of digital twins for UUV missions. The team integrated the digital twin architecture, software, and communication systems on a REMUS 100 vehicle, which were validated during at-sea tests.
The SBIR Phase 2 programme aims to define and demonstrate digital twin use cases for individual UUVs as well as multi-UUV missions with the goal of helping operators overcome undersea communication challenges and UUV mission interruptions.
The research programme included developing and performing in-water testing on a split onboard/offboard digital twin prototype architecture. This architecture enables the prediction of mission success likelihood and provides alternative achievable missions in real time to the operational commander based on environmental and UUV subsystem past, present and forecast states.
