摘要
本文为改进无陀螺捷联惯导系统解算的实时性 ,引入一种姿态阵更新的算法 ,并和常用的四阶 -龙格库塔法进行仿真比较 ,其结果是在不影响其精度的情况下 ,新算法的计算量和计算机时都有明显的减少。
This paper derives a new algorithm on attitude matrix renew in order to modifiey the real time capacity of gyroscopefree strapdown inertial navigation system,and compare it with ode 4 RungeKutta.The result shows that the calculation quantity and calculation time are evidently reduced without impacting its precision.This conclusion is helpful for improving the algorithm of the gyroscopefree strapdown inertial navigation system and choosing the calculation period.
