The GAGAN system advances safety and improves
efficiency of airlines operating throughout India.
Aircraft equipped with SBAS receivers may utilize
GAGAN signals in Indian airspace for en route
navigation and non-precision approaches without
vertical guidance. This capability will allow
aircraft to follow more efficient flight paths
through congested airspace, noise sensitive areas
or difficult terrain.
“The enhanced navigation capability available
through GAGAN improves air travel for all parties
- airlines, passengers and air traffic authorities,”
said Brian Hickey, Director, Raytheon Navigation
and Landing Systems. “In addition to enhancing
air traffic safety, the system will result in
increased efficiencies and lower costs for Indian
aviation.”
The GAGAN system includes 15 reference stations
strategically placed in India to optimize signal
availability, uplink stations, master control
stations, communication network and associated
software, all integrated to two Geostationary
Earth Orbit satellites transmitting GPS corrections
in C and L bands.
GAGAN is the fourth SBAS system certified for
operational use. The system provides coverage
for the entire Indian Flight Information Region
via broadcast signals from the Indian built GSAT
8 and GSAT 10 satellites. Raytheon has co-developed
three of the four world’s SBAS systems in
concert with national aviation and transportation
authorities.
