速率偏频激光陀螺寻北仪设计
Designing of North Finder Based on Rate Biased Ring Laser Gyro
摘要
设计了一套高精度的速率偏频激光陀螺寻北仪样机。样机主要由90型速率偏频激光陀螺和高精度单轴一体化转台构成,采用东西向二位置寻北方案,通过滑动平均法处理采样数据,降低量化误差的影响。在地理纬度28.2°处进行寻北实验,结果表明,静基座条件下200 s寻北精度优于16″。
Abstract
A high precision north finder based on rate biased ring laser gyro (RLG) is designed. The north finder is constituted by the 90-type RLG and a high precision one-axis rotation platform. The north finding experiment is realized by using two-position sampling scheme. To weaken the effect of quantification error, moving average method has been carried out. The experiment is carried out at the geography latitude of 28.2°. It is shown that the precision of north finder on stationary base is better than 16″ after 200 s.
