摘　　要：针对航天测量船船载测量设备工程背景复杂、数据产生过程复杂、误差源多的特点,采用三次等距B样条函数作为船载测量数据误差分离工具,对大量原始测量数据误差的统计特性进行检验分析,得出了船载外测数据不同于陆基测量的一些误差特性——非独立性、子段非正态性、需用高阶AR模型描述。Based on the complex engineering background, complex data generating process and multiple error sources of the measurement system of TT ＆ C ship, the cubic B spline function is used to separate the ship＇s measurement data error and analyze the statistics of lots of the original measurement errors. The analysis shows some of its error characteristics different from those of the data measured on land, namely, independence, segmented non-normality and can be approximated by higher order auto-regressive （AR） model.
