Abstract: Aiming at the space station with multi-configuration, multi-task and multi-moving parts, a dynamic simulation requirement for the view-field of extravehicular equipment was proposed. Based on the digital twin platform of space station and by using VR technology, the method for dynamic simulation of view-field of space station extravehicular equipment was studied. A universal visualization system was designed, and a lightweight visualization model including lightweight display of space environment, extracurricular moving parts and extracurricular sensors was built. The quantitative post-processing of view-field occlusion and relay satellite tracking, as well as the effective analysis of view-field of the sensor (antenna) were added to support the dynamic simulation verification of space station mission planning and flight program deduction. This method has been applied in the design of space station mission in orbit.
