摘要
针对目前利用单星分时测量方法检测惯性导航装备姿态误差存在的疑义,提出利用多星同步检测定位定向技术实现惯导姿态误差实时测量。对测量方案进行初步设计,重点介绍大视场多星定位定向技术的基本原理和数学模型。并对星体静态检测、动态检测和星图识别等关键技术进行理论分析计算,为提高惯性导航装备姿态误差实时测量精度提供了一种可行的方法。误差分析计算结果表明,静态条件下位置精度小于100m,满足测量要求。
The orienting and locating technology by multi-satellites synchronous detection is put forward to realize the real-time measurement of INS attitude error. The primary measure scheme is designed, in which the basic principles and mathematics model of the location and orientation technology for the wide FOV is emphatically introduced, and theory analysis is made on the key techniques, such as star static detection, star dynamic detection and star pattern recognition. It provides a feasible method for improving the real-time measure precision of the INS attitude. The error analysis and calculation results show that the location accuracy in static condition is less than 100 m, and this meets the measure requirements.
