Analysis of new Galileo signals at an GBAS compares noise and multipath in their performance to GPS L1 and L5. Even after smoothing, Galileo signals perform somewhat better than GPS and are less sensitive to the smoothing time constant.
Combining Galileo with GPS and GLONASSWhile a GPS-based GBAS will offer improved navigation services for aircraft, might these services be even better if the systems were to use satellites from other constellations besides GPS? In this month’s column, the authors show how GBAS protocols might be modified to accommodate multiple constellations, offering results of preliminary tests using GPS, GLONASS, and Galileo simultaneously.
