The GPS-Aided Geo Augmented Navigation (GAGAN) system, that seeks to advance safety and improve efficiency of airlines operating throughout India, has now got the certification level Required Navigation Performance.

The project, which has been jointly developed by Airports Authority of India, the Indian Space Research Organization and Raytheon, will now provide civil aircraft in Indian airspace access to more precision navigation data than before.

“The enhanced navigation capability available through GAGAN improves air travel for all parties - airlines, passengers and air traffic authorities,” said Brian Hickey, director of Raytheon Navigation and Landing Systems, adding that the system will also “result in increased efficiency and lower costs for Indian aviation.”

A release issued by Raytheon said the GAGAN system is a Satellite Based Augmentation System (SBAS) equipped with advanced air navigation technology. 

It is the fourth SBAS system certified for operational use.

Aircraft equipped with SBAS receivers can utilise 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,” it said.
