摘要
提出了用于边角网平差计算的附加系统误差参数自检校平差方法,分析了边角网的可靠性和精度。认为不能轻信它的表面现象,使用时应先引入两种类型观测数据仪器的系统误差参数进行平差,通过检验确信没有系统误差后,再做剔除系统误差参数的平差计算。
The paper presents methods of automatic checking adjustment of additional systematic error parameter in adjustment computations in side direction net. The author thinks the surface phenomenonshouldn't be followed blindly. In actual practice, two types of systematic error parameter used to observedata equipment should be introduced. After making sure that there exists no systematic error by checking,adjustment computation to eliminate systematic error parameter can be made.
