捷联惯导系统六加速度计配置方案研究

Six-accelerometers Configuration Scheme for SINS

在简述无陀螺捷联惯导系统原理的基础上,针对某工程应用背景的特点,提出了一种六加速度计三棱柱安装方式,推导了它的其力学编排方程,并对提高载体角速度计算值精度的方法进行了分析。通过仿真分析验证了该方案的可行性。

Firsts it briefly describes the principle of gyroscope-free stapdown inertial navigation system, then a six-accelerometers configuration scheme in triangular prism shape is presented according to the characteristic of engineering appliance. Furthermore, the mechanical calibration equation is formulated, and a method, which improves the carrier's angular rate calculation precision, is proposed and analyzed. The simulation result shows that the proposed scheme is feasible.
