摘要
大地测量的现代数据处理,需要顾及观测误差的相关性。本文对测边网中各相关数据的相关性进行了探讨,最终导出了测边网顾及自由项相关性计算测边中误差的公式。
I the preset-day data processig of geodesy, it is ecessary to cosider the observatioal errors. I this paper, the correlativity of the correlated data for trilateratio etworks is discussed. Fially, the mea error formula i distace measuremet of the trilateratio etwork, takig accout of the correlativity of the free terms is derived.
