IGS超快星历对GPS近实时反演水汽精度的影响研究
Research on effects of IGS ultra-rapid ephemeris on near real-time GPS inversing the water vapor
摘要
Abstract
The accuracy of IGS ultra-rapid ephemeris was verified by comparing the final ephemeris and ultra-rapid ephemeris.To the problem of low accuracy of IGS ultra orbit,a method of slipping choosing ephemeris was present to apply it in real inversing water vapor by GPS based on the observation data within one week of GPS Continuously Operating Reference Stations (CORS) in ARM test from NOAA.The comparison with the results obtained from final orbit shows that the accuracy of water vapor can satisfy the requirements of real-time application of GPS inversing water vapor.By comparing with sounding balloon water vapor,a conclusion that GPS water vapor is consistent with sounding balloon water vapor and detecting water vapor by GPS is feasible was drawn.关键词
