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,其工作不受天气制约。该设备有码头启动和海上应急启动两种启动模式,海上应急启动根据载体所处的航行工况分为锚泊启动、漂航启动、等纬度航行启动三种模式。该设备启动流程较为复杂,分为陀螺对准、陀螺启动、六次校准、系统标定、系统导航五个子过程,不同启动模式对应的外界工况对各子过程的启动细节存在一定影响,进而导致不同启动模式设备导航精度存在一定差异。针对上述问题,通过分析设备结构和工作原理,结合测量船设备多次应用该设备的工作经验,将静电陀螺监控器几种启动模式对设备启动子过程的影响进行了综合比较分析,最后结合不同启动模式设备的导航精度提出了对应的应用建议,为静电陀螺监控器在不同状态下的启动和应用提供借鉴。Electrostatic gyro monitor can continuously provide all-weather high-precision position and heading information. ESGM has two start-up modes, i.e. dock static start-up and maritime emergency start-up. According to the carrier＇s navigation condition, the maritime emergency start-up is divided into mooring start-up, drift start-up, same latitude sailing start-up. The boot process is rather complicated and can be divided into gyro starting alignment, gyro start-up, six calibration, system calibration, system navigation. The external working conditions in different start-up modes would have different impacts on the details of each starting process and hence the equipment＇s navigation precisions. In view of the above situation, the ESGM＇s structure and working principle is analyzed combining with the working experience of TTC ship, and a comprehensive comparative analysis among the several ESGM starting modes is studied. Finally an application suggestion is proposed, and it can provide effective application reference for ESGM in different states of the start-up.
