| 摘 要： | 基于陀螺寻北原理、旋转调制技术及惯导系统的误差特性,提出一种完全自主的导航系统,不需任何外界信息,可进行寻北、测定纬度和高精度的相对导航。给出了旋转调制寻北、测定纬度的原理,分析了旋转调制对导航性能的影响;计算机仿真结果表明,在没有任何初始信息的情况下,系统的方位精度可达1′,24h内的相对定位精度可达1n mile。

| Abstract: | An autonomous inertial navigation system (INS) was put forwards based on theory of finding north by gyro, rotation-modulation technology and characteristics of INS's error, which can be used to find north, measure latitude and navigate with high precision without any aided information. Basic theory of finding north, measuring latitude was presented, and rotation-modulation's effect to navigation was analyzed. It's validated by computer simulation that the system can provide azimuth with error less than 1' and relative position with error less than 1n mile. |
