Ground Based Augmentation System: A technique to improve GPS accuracy by transmitting an error correction from ground stations.
He said GBAS
helps make the job of ATM and piloting aircraft far easier, safely increasing an airport's operational capacity and enabling substantial maintenance and fuel savings by allowing aircraft to fly either complex or straight-in approaches, depending on air traffic demands.
In 2008 Polish Head Office of Geodesy and Cartography established a GBAS
called ASG-EUPOS as a part of EUPOS Project (www.eupos.org).
augments signals from the Global Navigation Satellite System to make them accurate and reliable enough to use during aircraft approaches and landings.
Geosynchronous Biased Augmentation Service (GBAS
) and Surface Biased Augmentation Service (SBAS)
In 1999, ICAO approved the GBAS
including the Global Navigation Satellite System (GNSS) technology under the Standards And Recommended Practices (SARPs) of Annex 10 of the Chicago Convention.
Additionally, three permanent stations of national GBAS
network--GLOG, LEGN and ZARY --were included in the processing.
Honeywell's SmartPath GBAS
system augments GPS signals so they can be used for precision navigation in the approach and landing phases of flight.
promises enough accuracy to replace any ILS system and do much, much more.
This course provides a description of the navigation techniques of B-RNAV, P-RNAV and RNP RNAV and explains how technologies like GPS, SBAS, GBAS
and the planned Galileo system will support future navigation requirements.
