Dynamic precise measurement of movement information constructs the foundation of guidance，navigation and control of various vehicles. The inertial technology is the only independent means to establish the position and attitude reference of a vehicle in all kinds of environments, so it is the basis of dynamic precise measurement of movement information. The development of inertial technology, including optical gyroscope and its inertial navigation system, MEMS gyroscope and accelerometer, atom gyroscope and accelerometer, other kinds of gyroscope and accelerometer, micro-technology for positioning, navigation and timing, and inertial executer, was reviewed in this paper, and the main technology problems of these gyroscopes, accelerometers and inertial navigation systems which are needed to be resolved in aerospace field were proposed. The main application of these inertial technologies in domain aerospace field was described, including application in satellites, launch vehicles, manned aerospace and moon explore. Finally, three development trends of the inertial technology in aerospace field were given.
