新型航向测量技术在海上测控任务中的应用研究

Application of New Heading Measure Technology in Marine Observation and Control Task

测量船惯性导航系统(惯导)输出的航向精度是影响海上测控定轨测轨精度的关键因素。测量船传统上使用经纬仪测星修正惯导航向,然而经纬仪作为光学设备,其工作性能严重受到天气影响,无法满足海上测控任务的需求。为解决上述矛盾,静电陀螺监控器(静电)航向测量技术和测姿GPS技术在测量船上逐步得到了推广应用。本文阐述了上述技术的工作原理,结合各种技术的特点和海上测控任务的需求,对新型航向测量技术在海上测控任务中的应用方法进行了研究。

Precision of heading outputted by inertial navigation system （inertial navigation） is the key factor to influence the precision of marine orbit determination. Traditionally, the survey vessel modifies inertial navigation heading by using transit. However, the performance of transit as the optical device is seriously influenced by weather, and it can not meet the demand of marine observation and control. To resolve the above problems, Attitude and heading measure technology of ESG is widely used in ＇FF＆C-ship. The paper presents the principles of above technology, combining with the characteristics of various technology and the demand of marine observation and control task, discusses the application of new heading measure technology in marine observation and control task.
