| 摘 要： | 旋转调制技术可以调制惯性器件常值误差,有效提高惯导系统的长航时导航精度。出于一种旋转调制式捷联惯导系统的研制需求,从旋转调制式捷联惯导的基本原理出发,提出了一种系统级双轴旋转调制式捷联惯导工程实现方案,并对其系统误差特性进行了深入的分析及仿真,找出了影响系统长航时导航精度的误差源。基于此。为了能仅利用系统自身旋转机构就可对主要误差源进行估计补偿,提出了一种系统级自标校方案。通过计算机仿真表明:此方案可以对影响系统长航时精度的主要误差项进行精确估计,是一种有效可行的系统级标校方案。

| Abstract: | The SINS based on Rotation-modulation technology can reduce the effect of constant drift of Inertial Instruments,and effectively improve the long-time navigation accuracy.To develop a SINS based on the Rotation-modulation technology,a scheme of systematic dual-axis Rotation-modulating SINS(RSINS)based on the basic principle of RSINS is presented,and its long-time navigation error characteristic is simulated and analyzed.The main errors which cause the long-time navigation error are found,and a systematic se... |
