| 摘 要： | 为探测系统误差和数据调整的需要，文中将误差模型分为两种基本形式，在此基础上给出了确定测线系统误差的3种模型：模型A、模型B和极大调整模型。在这3种模型中，模型A、B确定参数的差异主要体现在模型B将系统整体性影响按照平差空间结构分配至测线系统误差，极大调整模型原理的理论基础是模型A基准权的特例。实例计算验证，模型A能够较好地探测系统误差，模型B则适合于数据调整。

| Abstract: | In order to snoop the survey line systematic error and correct the data, the survey line error model has been further divided into two forms. Based on the three model, including model A, model B and maximum correction model, are presented to determine the survey line systematic error in this paper. Among the three models, the difference between model B and A is that the area systematic error is allotted to survey line systematic errors by model B. Maximum correc model is special cases of model A. In the end, the computational results show that model B is available to correct data and model A is available to snoop systematic error in marine survey net. |
