This paper proposes a real-time and high-resolution current system for underwater vehicle simulation testing based on global ocean data. The goal was to address the issue of existing systems simulation, whose tests cannot provide continuous velocity Thus, three-dimensional model (3D-OCM) built depths 0~4000 m via reconstruction raw data, fast-access information retrieval, interpolation. three interpolation algorithms’ data smoothness computational times were contrasted. spline bilinear algorithm performed best, taking about 22 milliseconds acquire anywhere underwater. comparative analysis revealed that constructed strongly in real time had good consistency compared with from National Marine Data Center (NMDC). Furthermore, running trajectories profiling float without interpolations contrasted, where more consistent between Newton interpolations. can support various marine phenomena vehicle’s hardware-in-the-loop (HIL) testing, it is meaningful valuable increasing effectiveness research development.
