摘要
简要介绍了参数约束平差的模型,与常规平差方法比较,参数约束平差数据处理简单,易于程序实现,以一GPS网为算例,用参数约束平差法获得了经典自由网平差、秩亏自由网平差、符合网平差的结果。
In this paper,a model of parameter constraint adjustment is introduced briefly.Compared with traditional adjustment methods,the data processing of the parameter constraint adjustment is more simple and easy to be programmed.Then taking GPS network as an example,the results of classical freedom network,rank deficient network and enclose network adjustment by parameter constraint adjustment are obtained.
