舰载机飞行试验时，舰上常配备有光电经纬仪测量系统。针对光电经纬仪引导时所遇到引导信息频率低、存在干扰的问题，提出了数据预测的外推内插法和粗差剔除的三点截止法；为了平滑切换引导源，提出了渐进式跟踪算法。实际数据比对表明，上述方法有效地解决了舰载复杂环境下的数据滤波、插值和多源信息的引导问题。最后，基于舰载GPS/INS组合惯导信息，推导出动基座光电目标引导算法公式。

The warship is generally equipped with photoelectric theodolite in carrier-borne aircraft flying test. Due to the low frequency of guidance source signal and disturbance from environment, the performance of the system is re-stricted. We proposed an extrapolation-interpolation method and a three points cut-off method to solve the prob-lem, respectively. To smooth the switch of different guidance sources, we also recommended a gradually track-ing algorithm. All the methods above resolve data filter, interpolation and multi-source problem effectively, which are usually encountered in the guiding photoelectric theodolite on the shipboard. At last, the guidance formulae of moving platform are established based on GPS/INS navigation information.
