Abstract
European Galileo global navigation system’s four in-orbit validation (IOV) satellites (E11, E12, E19, and E20) are able to calculate position accurately. The analysis of the IOV satellites’ measurements can provide insight into the performance of the Galileo system. To evaluate the performance of IOV satellites using measurements in the Shanghai, China, area signal-to-noise ratio (SNR) and multipath are used. We also suggest a method to calculate the four frequencies’ multipath error. When compared with global positioning system (GPS) satellites’ SNR, IOV satellites’ signal strength is stronger. In the aspect of multipath error, the IOV satellite is also less than GPS. The accuracy of single point positioning under open sky, under trees, and between tall buildings of a combined GPS/Galileo system is analyzed in the Shanghai area. The positioning result shows that the positioning accuracy of the combined GPS/Galileo system is better than the GPS system alone.
