摘　　要：静电陀螺监控器赤道陀螺仪处于低纬度地区启动或运行时,易出现未捕获的问题。针对该问题,通过仿真及试验,探明了在无减速器随动系统的复示误差发生变化的情况下赤道陀螺仪方位环随动系统性能与h角及所处纬度等的关系,进而揭示了在低纬度地区静电陀螺监控器赤道陀螺仪易出现未捕获问题的原理所在。同时证明了高品质、高动态性能的静电陀螺监控器无减速器复示系统及高度环、方位环随动系统是十分重要的。When ESGM＇s equatorial gyroscope starts or runs in low-latitude, the problem of can not capturing the signal is liable to occur. To solve this problem, through the simulation and test, the relationships between the performance of equatorial gyroscope azimuth servo system and h angle and latitude etc. is clarified in the case that there are no changes in deceleration servo system error. Then the principle of the problem is revealed. Meanwhile it is proved that the decelerator-flee servo system of ESGM with high-quality and high dynamic performance as well as the altitude and azimuth servo system are very important.
