Egnos Limitations over Central and Eastern Poland – Results of Preliminary Tests of Egnos-Eupos Integration Project

The problem of insufficient accuracy of EGNOS correction for the territory of Poland, located at the edge of EGNOS range is well known. The EEI PECS project (EGNOS EUPOS Integration) assumes improving the EGNOS correction by using the GPS observations from Polish ASG-EUPOS stations.

One of the EEI project tasks was the identification of EGNOS performance limitations over Poland and services for EGNOSS-EUPOS combination. The two sets of data were used for those goals:

statistical, theoretical data obtained using the SBAS simulator software,

real data obtained during the measurements.

The real measurements were managed as two types of measurements: static and dynamic. Static measurements are continuously managing using Septentrio PolaRx2 receiver. The SRC permanent station works in IMAGE/PERFECT project. Dynamic measurements were managed using the Mobile GPS Laboratory (MGL). Receivers (geodetic and navigation) were working in two modes:

determining navigation position from standalone GPS, determining navigation position from GPS plus EGNOS correction.

The paper presents results of measurements’ analyses and conclusions based on which the next tasks in EEI project are completed
