摘要
针对电控罗经误差随纬度变化而变化的弱点,从原理上分析了其重要原因,提出了两种可变修正回路传递系数方法,经仿真和实际应用证明,能大幅减小罗经在高纬度下的误差。
The gyrocompass error changes with the variation of latitude.The main reasons from principle are analyzed, two kinds of variable correction loop transfer coefficient methods are presented.The results of simulation and practical application prove that they can greatly decrease the error of the gyrocompass in high latitude areas.
