Selection of Optimal Scheme in Resolving of Regional Tropospheric Delay
摘要
Abstract
The sequence of precipitablewater ,retrieved by tropospheric delay at quasi re‐al‐time ,is the premise of weather forecasting in short time ,especially the severe weather mo‐nitoring ,thus the key of calculating results in high precision and meteorological products is w hich proper and even optimal computing method to be selected .From perspective of researc‐hing precision in data processing over tropospheric delay thoroughly ,this paper summarizes several plans influencing quality of data results ,as well as optimal strategies in data process‐ing regarded as integrative and high reliability relatively are put forward by comparing and verifying synthetical susceptibility and effectiveness of various approaches composed by se‐lection of elevation cutoff angle and observation time ,choice of satellite ephemerides and computing methods ,also decision of w hether auxiliary stations should be add in or not and determination of its best number and impaction of end effect as well ,it provides a reference and help for GPS data processors and related professional students having a better under‐standing and mastery for this content .关键词
