India lately performed Asia’s first demonstration of performance-based navigation for helicopters utilizing GAGAN satellite tv for pc expertise for a flight from Juhu to Pune. Civil Aviation Minister Jyotiraditya Scindia known as it a high quality instance of the “Indian aviation sector blazing a trail in innovation!” As the nation achieves main milestones within the discipline of Air Navigation Services (ANS), this is all it’s good to learn about GAGAN satellite tv for pc expertise that’s set to rework Indian aviation.

What is GAGAN?

GAGAN (GPS Aided GEO Augmented Navigation) is an Indian Satellite-Based Augmentation System (SBAS) collectively developed by the Indian Space Research Organisation (ISRO) and Indian Space Research Organisation (ISRO). It is the primary such system developed for India and neighbouring nations within the equatorial area. Directorate General of Civil Aviation (DGCA) licensed GAGAN System in 2015 for Approach with Vertical Guidance (APV 1) and en-route (RNP 0.1) operations. It ought to be famous that there are solely 4 Space-Based augmentation methods out there on the earth particularly India (GAGAN), Europe (EGNOS), Japan (MSAS) and the US (WAAS). GAGAN is the primary such system developed for India and neighbouring nations within the equatorial area.

The GAGAN gives further accuracy, availability, and integrity required to allow customers to depend on GPS for all phases of flight, from en route by means of method for all certified airports throughout the GAGAN service quantity.

GAGAN additionally gives the aptitude for elevated accuracy in place reporting, enabling extra uniform and high-quality Air Traffic Management (ATM). Moreover, GAGAN gives advantages past aviation to all modes of transportation, together with maritime, railroads, highways and public companies reminiscent of defence companies, the telecom trade, safety companies and private customers of place location functions.

How GAGAN works?

According to the Airports Authority of India (AAI), GAGAN makes use of a system of floor stations to offer obligatory augmentations to the GPS customary positioning service (SPS) navigation sign.

“A network of precisely surveyed ground reference stations (Indian Reference Stations- INRES) is strategically positioned across the country to collect GPS satellite data. Using this information, the master control centre (Indian Master Control Centre- INMCC) generates messages to correct any signal errors. These correction messages are then uplinked through (Indian Land Uplink Station – INLUS) and broadcast through communication satellites (Geostationary) to receivers onboard aircraft using the same frequency as GPS,” AAI stated.
