The 28th Satellite-based Augmentation Systems Interoperability Working Group endorsed the “message definition” for a new secondary SBAS channel — to be known as L5, along with the current L1 — for the planned second-generation SBAS systems, which will utilize dual-frequency multi-constellation signals.
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.
