摘要
在无陀螺捷联惯导系统中 ,角速度的解算精度是技术关键 [1]。由于角速度是由载体上加速度计敏感出的比力解算出的 ,选择合理的方法解算角速度是提高其精度的根本。文中提出高解算精度的新途径 ,并以某型导弹为例 ,对其进行实时仿真 ,证明了它的可行性。
In the gyroscopefree strapdown inertial navigation system,the angularvelocity calculation precision is a key technical point.Since angular velocity is calculated by apparent acceleration that is sensed through accelerometer on board,it is the basement to choose a reasonable method in order to improve the precision.This paper provides a new way for improving the precision, and takes a certain missile as an exemple to simulate in realtime.The simulation result shows that it is feasible.
