| 摘 要： | 为满足长寿命卫星对高精度、高可靠、低功耗、轻重量的姿态测量系统的需求,构建了一种基于半球谐振陀螺与星敏感器的星载姿态测量系统。针对国产半球谐振陀螺和加速度计结构特点,建立了惯性器件配置结构,完成了系统的相关标定,开发了以四元数为基础的姿态算法,利用卡尔曼滤波技术,将惯性姿态测量系统与星敏感器进行组合,实现了工程样机设计。测试表明,在实验室环境下,静态姿态精度达到13.9″(峰值),动态姿态精度达到15.4″(峰值),所研制的工程样机的精度指标能够满足高精度卫星的使用要求。

| Abstract: | A spaceborne attitude measurement system(SAMS) based on Hemispherical Resonator Gyro(HRG) and star sensor is developed in this paper in order to meet the requirements of long life satellites,such as high precision,high reliability,low power consumption and light weight.In view of the characteristics of domestic HRG and accelerator,a new structure configuration is designed and tested.With quaternion-based attitude algorithm,the Kalman filter is introduced to integrate the measurements of AMS with star sensor.The tests in laboratory environment shows that the static attitude precision arrives 13.9″(peak),and the dynamic posture precision reaches 15.4″(peak),hence the engineering prototype of SAMS meets the requirements of high precision satellites. |
