常规控制网平差程序设计与实现

The Design and Implementation of Conventional Control Network Adjustment Program

根据控制网间接平差的基本原理,基于Visual C++6.0设计和实现了一款控制网平差计算程序GNetAdj,该程序可实现水准网、测角网、测边网、边角网等常规控制网的平差计算与精度评定.重点探讨了特殊情况控制网的近似坐标推算方法,以及不同类型观测值较为合理的定权方法.最后通过一算例验证了程序的正确性.

GNetAdj is based on the principles of indirect adjustment, and it is designed by Visual C ＋ ＋ 6.0. It can realize the adjustment and estimate of precision for level network, triangulation network, trilateration network, triangulateration network and other conventional control networks. Some methods of calculating approximation coordinates for special control network are discussed, and some methods of fixing the weight of different observations are analyzed. Finally, the program is verified by a case, and the result shows that it has good practical value.
