This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:Processing and analysis of geodetic observations of nowadays used (GPS), modernized (new GPS signals), completed (GLONASS) and developed (Galileo) Global Navigation Satellite Systems (GNSS) with the aim of precise positioning and monitoring of temporal changes of position. Integrated processing of permanent GPS and GLONASS observations within the European Permanent Network (EPN). Analysis of GLONASS contribution to stability of reference stations, contribution to estimation of seasonal and short-term variations, and to troposphere and ionosphere modelling. Development of modules for new software package for processing of undifferenced GNSS observations in the Precise Point Positioning (PPP) mode. Modules for reduction of observed pseudoranges, transformation of reference frames, and systematic phenomena elimination. All these activities are aimed to build the PPP software package for common analysis and precise positioning using GPS, GLONASS, and Galileo satellites in homogeneous coordinate and time reference frame.
