Combining Galileo with GPS and GLONASS
While 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. read more
