摘　　要：为解决远洋测量船在海上缺少精度校准目标的问题,就光电经纬仪采用海上跟踪恒星的方式,从选星、引星和数据解算3个方面对远洋测量船上惯性导航设备提供的航向数据校准的相关技术进行了分析研究,并基于现有条件和技术提出一种结合正弦波拟合方式对船摇数据进行滤波和外推的算法。该算法通过对船摇数据进行抛物线差值细分,再经过最小二乘法获得正弦曲线拟合参数。在随"远望"号测量船出海期间对此方法进行了验证,实验结果证明该方法可有效提高船摇隔离度、增强空间目标跟踪能力,且在解算航向误差时具有较高的准确性和一致性。To solve the problem of lack of precision calibration target for survey vessel at sea,a research on the technology of course calibration identificationfor inertial navigation equipment by electro-optical theodolite from three aspects： selecting star,leading to star and calculating record data is conducted. Combined with existing conditions and technologies,an algorithm for filtering and extrapolating the data of ship shaking with sine wave fitting method was proposed. This algorithm obtains the sine curve fitting parameters by the least square method after the parabolic difference subdivision of the ship shaking data. During the sea with ＂Yuan Wang＂survey vessel,the method described was verified. The results show that the method can improve the isolation of ship shaking,the ability of tracking space targets and the accuracy and consistency while calculating the course error.
