本文重点分析了天地往返运输系统对导航、制导控制系统的特殊要求,以及导航、制导控制系统在天地往返运输系统中的重要作用;导航计算中采用的主要计算公式、校准方法和制导控制函数适合应用的形式。文中简单说明四框架惯性平台系统的两种框架配置形式及捷联式惯导系统适合在轨道飞行段使用,并给出速率捷联系统解算姿态角的解算式;文中还说明在轨道飞行段采用星光技术的必要性和使用方法;以及以电子计算机为核心的电子系统冗余技术使用的必要性及冗余技术对计算机的使用要求。
In this paper, the special requirements for the navigation and guidance control system of the round-trip transportation system and the important role of navigation and guidance control system in the transportation system between heaven and earth are analyzed. The main calculation formulas, calibration methods and guidance control functions used in navigation calculation are suitable The form of application. In this paper, two kinds of frame configurations of the IVF inertial platform system and the strapdown inertial navigation system are suitable for use in the orbital flight section. The solution of the attitude angle of the strapdown strapdown system is given. The paper also shows that in the orbital flight section The necessity and use of Starlight technology; and the necessity of using redundant technology of electronic system with the core of electronic computer as well as the requirement of using redundant technology on the computer.
