GNSS网参数估计中基准定义方法研究

摘要

Taking the software of GAMIT/GLOBK as an example, this paper discusses and deduces the principle and implementation process of datum definition with HELMERT transformation, and poses the concept of system constraints, then verifies these conclusion using field data.%以GAMIT/GLOBK软件为例,论述了利用HELMERT参数转换进行基准定义的原理并推导了其实现过程,提出了附加系统约束,并根据实测数据对附加系统约束进行了验证.
