摘　　要：为分析静电陀螺监控器无减速器随动系统复示误差对海上"六次校"的影响情况,找到"六次校"不能正常通过的原因及解决方法,通过对无减速器随动系统复示误差、陀螺仪高度角变化量以及方位角之间关系的理论分析,结合海上动态试验,探求了一种根据陀螺方位角适时调整航向,上、下陀螺分时进行"六次校"的方法。通过多次试验,证明在无减速器随动系统复示误差或船摇幅度较大,"六次校"不能正常通过时,采用该方法能使系统正常进行"六次校",成功率达到了100%。采用上、下陀螺分时进行"六次校"的方法,使静电陀螺监控器在海上启动的条件相对放宽,更加适用于水面舰艇。To analyze the relationship between the deceleration-free servo system＇s tracking error and electrostatic gyroscope monitor＇s six-time calibration,the reason and the solution method of six-time calibration working abnormally are given.By analyzing the academic relationship among the deceleration-free servo system＇s tracking error,h angle transformation and azimuth angle,a new six-time calibration method is proposed.In this method,the equatorial gyroscope and polar gyroscope are calibrated at the different time according their azimuth angles.By several dynamic tests,the method is proved effectively with 100% success rate when the deceleration-free servo system＇s tracking error or the ship rocking is over the mark.By using the method,the electrostatic gyroscope monitor is more applicable in the ships.
