Abstract

The features of navigation devices based on fiber-optic gyroscopes cause problems in their practical applications and require calibration prior to being used. The algorithms for accumulating and processing the information of strapdown inertial blocks (SIBs) based on fiber-optic gyroscopes and units determining the stars’ coordinates (UDSC) are given. The calibration algorithms are modified to reduce the onboard computer memory and take into account the time limitations of the program execution. The results of the modeling prove the efficiency of the proposed solutions.

基于光纤陀螺仪的导航设备模型参数校准

摘要

基于光纤陀螺仪的导航设备的功能在其实际应用中会引起问题，并且在使用前需要进行校准。给出了基于光纤陀螺仪和确定恒星坐标（UDSC）的单位的捷联惯性块（SIB）信息的累积和处理算法。修改了校准算法，以减少板载计算机的内存并考虑程序执行的时间限制。建模结果证明了所提出解决方案的有效性。
