针对大型特种载体位姿测量系统结构复杂、可靠性差、成本高的问题,基于光纤陀螺(FOG)捷联惯导系统(SINS),采用卫星、天文2级组合导航,提出了实现载体导航信息精密测量的新方法,给出了组合导航系统的滤波结构、误差方程、数学模型。数据分析与精度评估的结果表明,采用小型化、高可靠性、低成本的FOG SINS的组合导航方法能够实现载体速度、位姿的精密测量。基于FOG SINS的载体位姿的精密测量方法是实现导航低成本、高性能的一种有效途径。
Aiming at the problems of complex structure, poor reliability and high cost of the large special carrier pose measurement system, based on the FOG SINS (SINS), the combined satellite and astronomical 2-level navigation is proposed to realize the precision of the carrier navigation information The new measurement method, the filter structure, error equation and mathematical model of integrated navigation system are given. The results of data analysis and accuracy evaluation show that the combined navigation method based on FOG SINS with miniaturization, high reliability and low cost can realize the precision measurement of carrier velocity and pose. The accurate measurement of pose and attitude of FOG SINS is an effective way to realize low cost and high performance of navigation.
