Abstract:Augmented reality(AR) combines the virtual word with the real world through display devices,it improves the human-computer interaction model to enable users to interact in a new environment where the virtual and real are combined, The application of AR technology in the design, assembly and inspection of the satellite cable can optimize the design and layout of the cable, improve the efficiency and quality of the cable assembly, save the cost and period of product development. This paper summarizes the application demand of satellite cable to AR technology, analyzes the key technology of engineering application, explored the application of AR technology in the development and assembly of satellite cables.
