摘要
基线解算是GPS数据处理中的重要环节。文章针对GPS双差观测序列中难以消除的非模型化误差,应用小波变换进行去噪,以提高GPS双差观测值的信噪比和精度;并提出了基线精化技术,有效解决了基线解算的关键问题,即模糊度解的快速固定和有效性,提高了基线解算的可靠性和平差结果的精度。
Baseline processing(BP) is an important part in GPS data analysis.This article,by analyzing the irremovable non-modeled errors in GPS double-differenced observation series,applying wavelet transformation to reduce noise so as to improve the ratio and accuracy of signal noise in GPS double-differenced observation.It also proposes the baseline refining technology,which has effectively solved the crucial problems,and strengthened the reliability of baseline processing and the accuracy of adjustment results.
