摘　　要：静电陀螺监控器可以全天候提供连续高精度的位置及航向信息,且不受天气制约。但是在低纬度海域静电陀螺监控器会出现六次校准频繁重置的现象,导致静电陀螺无法获得准确的漂移模型系数,进而影响到设备的正常工作。针对上述现象,通过分析设备结构和工作原理,构建了赤道陀螺随动性能数学模型,推导出赤道陀螺方位环随动速率与所在纬度相关性的计算方法,研究了六次校准重置与赤道陀螺随动性能的关系,提出了低纬度地区六次校准重置现象的规避方法。研究结果有效拓展了静电陀螺监控器的启动纬度范围,提高了设备应用效益。Compared with traditional optical theodolite, a high-precision course information can be supplied by ESGM at all-weather. While in low latitude areas, the Six-Calibration of ESGM may be frequently reset by the poor follow capability of equator-gyro, and the accurate ESG drift model coefficient is unable to be obtained. In this paper, according to the former phenomenon, the follow capability of equator-gyro about ESGM is calculated in principle, and the relation between six-calibration and capability of equator-gyro is analyzed. An effective method is put forward to avoid six-calibration to be reset in low latitude areas. The research results show that the ESGM start latitude range can be effectively expanded, and the application efficiency can be improved by the proposed method.
