Union Civil Aviation Ministry launched GAGAN System

GAGAN stands for GPS Aided Geo Augmented Navigation

It is an inter-operable Satellite Based Augmentation System (SBAS)

India is the fourth nation after the US, Europe and Japan to have SBAS

GAGAN is the first SBAS system in the world to serve the equatorial region.

The Indian Space Research Organization (ISRO) announced the complete operationalisation of the GPS Aided Geo Augmented Navigation (GAGAN).

The final operational phase of the system commenced as it began broadcasting APV1 Certified signals.

With this, India has become the fourth nation after the US, Europe and Japan to have inter-operable Satellite Based Augmentation System (SBAS). Also, GAGAN is the first SBAS system in the world to serve the equatorial region.

Earlier Director General of Civil Aviation (DGCA) gave its nod for GAGAN for enroute operations (RNP 0.1) and subsequently for precision approach services (APV 1).

Features of GPS Aided Geo Augmented Navigation (GAGAN) System

1. It is a Satellite Based Augmentation System (SBAS) developed jointly by the Airports Authority of India (AAI) and Indian Space Research Organization (ISRO).

2. Its primary objective is to establish, deploy and certify satellite based augmentation system for safety-of-life civil aviation applications for the Indian air space.

3. It plays an important role in safety of life applications in transport, sensitive commercial applications and liability-critical applications needing legal course.

4. It offers free enhanced satellite navigation signals by correcting deviancies in GPS signals by deploying ground based navigational infrastructure.

5. The system is inter-operable with other international SBAS systems like US-WAAS, European EGNOS, and Japanese MSAS etc.

6. It has been developed at an estimated cost of 774 crore rupees.

It will enable transition of the air traffic management system to satellite-based seamless navigation across continents covering the airspace from Australia to Africa as well as west Asia to China and Russia.
