摘要
静电陀螺监控器在海上应急启动时,要求载体等纬度匀速直线航行,这种条件很难满足。为此,通过分析静电陀螺监控器的启动原理和方法,完成设备在锚泊条件下海上启动试验。试验结果表明,锚泊启动过程中采取适当措施可使静电陀螺监控器在动态条件下完成启动和标定,导航精度接近码头启动的指标要求。这可在系统应急启动情况下降低对舰船航行工况的要求,为静电陀螺监控器在不同航行状态下的海上启动提供借鉴。
The emergency start of electrostatic gyro monitor （ESGM） requires sailing at uniform velocity and constant latitude, which is difficult to achieve. In order to solve this problem, a test on anchoring start of ESGM in dynamic conditions was designed by analyzing the starting principle of ESGM. The result shows that, by taking reasonable technical means in controlling the start process, the starting-up and calibration of ESGM can be well implemented in anchoring start, and the navigation accuracy is closed to the index requirement of starting at pier. The achievement can effectively liberalize the navigation mode management when emergency starting-up is operated, and it also provides a reference for the further application of ESGM on different navigation conditions at sea.
