I. Introduction
Aerospace is one of the most challenging high-tech fields in the world today. To a certain extent, it can reflect the overall national strength of a country. It can reflect the achievements of modern science and technology in many fields, and at the same time put forward development needs for high-tech in various fields. In 2019, China launched 34 carrier rockets throughout the year, with 81 spacecraft launched. The number of launches occupies the first place in the world and the number of spacecraft launched second in the world. Simulation technology has played a major role in the entire aerospace field due to its economic, safe, controllable and high-efficiency characteristics. At present, the most commonly used simulation software in the world is STK from AGI, but it cannot provide users with an immersive experience. Most simulation software realizes the visualization of image data on a two-dimensional display screen. When three-dimensional image data is displayed on a two-dimensional display screen, there will inevitably be “loss” of data. The design of Hololens-based scene system for spacecraft simulation in this paper will visualize the spacecraft's orbital data or design image data in an immersive space, so that researchers can more intuitively understand the data.
