摘要
介绍了GPS遥感大气水汽含量技术的类型、实时GPS遥感水汽技术的研究现状以及地基GPS大气探测的基本原理。提出了用非差精密单点定位模式进行实时GPS遥感水汽探测的基本构想和需要解决的关键问题,并对非差精密单点定位的主要误差源进行了简要分析和评述。
The methods of remote sensing of atmospheric water vapor by using GPS and the present situation of real-time GPS water vapor detecting are introduced. Principles of remote sensing of atmospheric water vapor by ground-based GPS are discussed. The basic idea and some key problems of real-time GPS water vapor detecting by using undifference precise point positioning (PPP) technique are introduced, and main error resources by using undifference precise point positioning (PPP) are analyzed and remarked on.
