附加系统参数平差在二维控制网平差中的应用

Application in Two-dimensional Control Network Adjustment with Additional System Parameters Adjustment

用导线建立的地面二维平面控制网中,距离观测量中往往存在测距固定误差和比例误差2项系统误差,难以消除。研究了在进行数据处理时,利用顾及观测值系统误差的数据处理方法。结果表明,通过引入附加参数对系统误差进行补偿,相对于经典的平差而言,获得的结果更加可靠。

In the process of establishing a two-dimensional ground control network, distance measurement contained the fixed error and proportional error systematic error. During data processing, study the processing method on the concept of the measurement system error and its application. The results show that, by introducing additional parameters to compensate for systematic errors are more reliable compared with the classic adjustment.
