Targeting the complex and ever-changing working environment and task requirements of unmanned equipment at sea. The unmanned equipment testing system based on environmental simulation and motion simulation is a set of digital equipment modeling and simulation testing kits composed of various R&D testing software. It supports the establishment of digital models for surface and underwater (unmanned) equipment, simulation of common loads of unmanned equipment, and development and testing work such as design verification, capability evaluation, and training transfer based on digital models under fully virtualized or semi physical conditions.
