基于数据融合的轨道计算方法研究

Research on Orbit Calculation Method Based on the Data Fusion

目前测量船轨道计算使用的是基于单一测量设备的外测数据,而在实际任务中往往会有来自多种不同测量设备的外测数据。每种测量设备对目标的跟踪精度是不同的,利用数据融合方法对不同精度的测量数据进行综合利用,可以提高轨道计算结果精度,也为轨道预报及指挥决策提供更为准确的参考数据。

The survey ship track are calculated using the measured data based on a single measurement equipment, but in actual tasks, it often comes from a variety of different measuring equipment for tracking data. A measuring device for the target tracking accuracy is different, using the method of data fusion for different accuracy of measured data for comprehensive utilization, can improve the accuracy of the calculation results for orbit, also provide more accurate reference data for orbit forecast and decision-making.
