This study evaluates EGNOS system accuracy against GPS, improvements, and receiver performance. Findings show EGNOS improved accuracy in Warsaw but didn't in some instances. Commercial receivers lack SBAS signal reception. Further testing aims to integrate mobile testing with an INU for enhanced results.

Accuracy Analysis of the EGNOS System During Mobile Testing Douglas Aguilar Leszek Jaworski Marcin Kolodziejczak Warsaw, Poland
Test Objectives • Objectives • Check accuracy corrections of the EGNOS (PRN 126) system against GPS signals • Compare integrity and availability of GPS and EGNOS (PRN 126) signals
Conclusions • Availability in Warsaw • Analyzing 10 days of static testing has shown EGNOS availability at 98% of the time • Accuracy in Warsaw • Overall, EGNOS improved accuracy • During some observations EGNOS did not improve GPS accuracy • Receiver used less satellites with EGNOS • A minimum of three RIMS stations need to monitor the same GPS satellite to provide EGNOS corrections
Conclusions • Commercial Receivers • Some commercial receivers have EGNOS options but do not receive SBAS signals • Further Testing • Find popular commercial receivers that provide EGNOS corrections • Integrate mobile testing with an INU
