摘要
随着测绘新技术的发展，测量平差已经发展到新的近代平差阶段，而“3S”技术的迅速发展更进一步推动了近代平差的发展．本文通过简要介绍GIS空间数据的误差分析和平差模型，以及GPS基线向量观测值的选择，整周未知数的求解和动态GPS的卡尔曼滤波等，来说明测绘新技术与近代平差的相互推动作用，并论述近代平差的发展方向。同时，对近代平差发展中的几个值得商榷的问题提出了看法。
With the development of new technology in surveying and mapping, surveying adjustment has reached to the modern adjustment stage, and '3S' technology has further promoted the development of modern adjustment. Through discussing error analysis and adjustment models for spatial data in GIS, and the selection of baseline observations in GPS, the computation of the ambiguity parameters and Kalman filtering in dynamic GPS, this paper explains the mutual promotion between the development of new surveying technology and modern adjustment and expounds the future development directions of modern adjustment. Some views about the prob1ems to be dealt with in the development of modern adjustment have been put forward.
