基于最小二乘法的海基双站测量数据综合处理

针对测量船执行海上任务单船数据处理及弹道参数计算受时间和弧段限制局限性的问题，提出了采用加权最小二乘法解算双站目标坐标的综合数据处理方法,并在综合后的数据库增加了跟踪时间及重要特征点弧段数据，提高了位置及其他弹道参数的估计精度。该方法的推广对改进测量船数据处理方法和技术、提高弹道状态估计精度均具有积极的意义。

Data processing based on least squares for sea-based bi-station measurement

For the shortcoming of the time and arc constraints of single ship in TT&C tasks,the weighted least squares method is applied to calculate the target states based on bi-station.Through adding the tracking time and the arc data of the feature points in the synthetic database the precision of the positioning and the other states estimation is greatly improved. The application of the method is helpful to improve the data processing technology and trajectory states estimation precision.
