航天器惯性及其组合导航技术发展现状

航天器是在地球大气层以外运动的飞行器，也包括部分从宇宙空间返回地球的飞行器。在航天器的飞行过程中，惯性敏感器是实现航天器姿态确定、速度变化测量的关键敏感器之一。随着航天器任务的不断扩展，航天器对惯性器件的使用日趋复杂，高精度定姿、惯性导航、组合导航等技术在应用深度和广度上不断发展。以此为背景，对航天器惯性技术的发展脉络进行了全面的梳理和总结，包括惯性技术的使用方式、技术现状以及未来发展等几个方面的内容。

The Development of Inertial and Integrated Navigation Technology for Spacecraft

Spacecraft is a vehicle fighting in extra-atmosphere, and also includes some earth reentry vehicles. During flight, inertial technology is critical important to assist the spacecraft to determine its attitude and velocity increment. As the missions become more complex, the application fields of inertial sensors expand rapidly and cover high precision attitude determination, inertial navigation, integrated navigation, et al. On this background, the development context of inertial technology for spacecraft is discussed in this paper, including the category of usage, present situation and future needs.
