Orbital mechanics of spacecraft is a basic discipline in the aerospace field.Orbital maneuver is an important part of the teaching of orbital mechanics.Textbooks are the carrier for implementing teaching.This paper systematically sorts out typical orbital mechanics textbooks of spacecraft and their characteristics,analyzes the contents of relevant chapters of orbital maneuver in typical orbital mechanics teaching materials at home and abroad.The study summarizes that the current orbital maneuver teaching content has inconsistent sources of orbital maneuver power,the connotation of orbital change is not clear,and orbital adjustment and phase modulation maneuvers have not received widespread attention.In order to provide support for the teaching reform of orbital mechanics,we should focus on undergraduate teaching,highlight the high order,innovation and challenges,and build a reform idea for the teaching content of orbital maneuver.
