Global positioning should belong to: Space Science and Technology Major Introduction to Space Science and Technology Major: Space Science and Technology Major is a newly established major to adapt to the development of my country’s space science and technology undertakings.

The teaching and research contents of the space science and technology major include: using observation instruments and experimental equipment on various types of spacecraft to study the physical and chemical characteristics and evolution processes of solar-terrestrial space, interplanetary space, and stellar space environments; studying celestial bodies (

Including the structural characteristics of the earth, the sun, planets and their satellites, comets, asteroids and other stars) and their formation and evolution processes; using space platforms to conduct various scientific experiments that cannot be achieved in ground laboratories, and studying microgravity conditions

various physical and chemical processes, life phenomena and the generation of materials; space exploration technology using sounding rockets and various types of spacecraft.

At present, the main research fields of space science include the following branches of disciplines: space physics, space astronomy, space weather science, microgravity science, space life science and space earth science.

Space technology mainly refers to technologies related to space scientific research and applications, including space exploration technology, satellite and space station application technology, spacecraft protection technology, etc.

Responsible for a large number of National 863, National 973, and National Defense Science and Technology projects related to deep space exploration mission planning and scientific target formulation, space debris protection, spacecraft orbit design, spacecraft on-orbit services, space remote sensing technology, integrated navigation and autonomous navigation technology, etc.

Scientific research projects of the Working Committee on Civil Aerospace and National Natural Science Foundation of China.
