Launch Vehicle Guidance Technology and its Development Trend

This paper analyzed the domestic an overseas development of launch vehicle guidance technology, and described the principles of perturbation guidance, interactive guidance and other technologies that are widely used at present, the application conditions and engineering applications of different guidance methods are also described. Based on the theoretical and actual attitude information of a certain type of launch vehicle, the reliability, adaptability, precision and problems in application of interactive guidance are discussed. In the future, with the rapid development of low cost, reuse, artificial intelligence and the increase of requirements such as high reliability, fast response and high fault-tolerant, self-adapting guidance technology will be the development direction of smart launch vehicles.
