基于高频GPS和强震仪观测实时监测地表形变 涂锐 著 2017年版

基于高频GPS和强震仪观测实时监测地表形变  

作者:涂锐 著  

出版时间:2017年版 

内容简介 

涂锐著的《基于高频GPS和强震仪观测实时监测地表形变(英文版)》系统地介绍了GPS和强震仪数据融合处理的基本原理和算法模型,主要包括松组合模型、紧组合模型、自适应组合模型、改进的松组合模型、改进的紧组合模型、组合处理中关键技术问题、 

基线漂移与地表倾斜的关系以及各传感器观测的特点分析等。对GPS测速增强解算和基于联网模式的强震仪基线漂移校正也进行了分析介绍。 

本书可供从事G**灾害*测预警方面的科研、生 

产人员参考,也可作为高等学校大地测量与地球物理专业的教材使用。
