Account of the EPN Special Project'Troposphere Parameter Estimation'

摘要

Since GPS week 1108 (June 2001) the Local AnalysisCentres (LACs) of the EUREF Permanent Network (EPN)are producing and delivering solutions of Zenith TotalDelay (ZTD) parameters. The solutions are calculated foreach day, on a weekly basis according to and consistentwith the weekly coordinate solution. The ZTD parametersare delivered in the so-called troposphere SINEX format[IGS 1999]. Since GPS week 1185 all16 LACs are partici-pating to this EPN project.
