摘要
在加密扩展网的平差时,原始数据误差的影响不可避免。加密扩展网的半动态数据处理方法,比较合理地考虑了原始数据误差的影响,本文介绍半动态数据处理的原理及数学模型,并对其应用中的各种情况加以分析。
The influence of initial data errors in the densification andextension of control network is unavoidable.However,in themethod of semi-dynamic data processing.such influence is quitereasonably taken into consideration in giving weight of obser-vation equations.This paper introduces its principle and itsmathematical models,and discusses some essentials that shouldbe considered in application.
