Accuracy Analysis of the EGNOS System During Mobile Testing
1 Space Research Center, Warsaw, Poland
ABSTRACT: The European Geostationary Navigation Overlay Service or EGNOS has been operational and broadcasting signals on PRN120 and PRN126 as of July 2006. EGNOS is designed to broadcast embedded correction signals in Europe which will provide improved performance with GPS. There are three EGNOS geostationary satellites PRN codes 120,124 and 126. The three satellites have positions 15.5 degrees west fro PRN 120, 25 degrees east and 21.5 degrees east for PRN?s 126 and 124. Satellite PRN124 is still in the test phase. The Space Research Centre has performed a mobile testing to demonstrate how EGNOS improves GPS accuracy. A mobile GPS laboratory was used to collect GPS data in the rural outskirts of Warsaw. Two receivers and one antenna were used to collect kinematic and navigation data. Post-processed GPS position and height deviations are compared to the solution given when GPS is augmented with EGNOS. The summarized results in this paper show that GPS augmented with EGNOS greatly improves position accuracy.
