INTRODUCTION

The GPS aided geo augmented navigation or GPS and geo-augmented navigation system (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the AAI & ISRO.

ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS).

Satellite Navigation service is an emerging satellite based system with commercial and strategic applications. ISRO is committed to provide the satellite based Navigation

On 15 April 2010, it was attempted to launch

the first GAGAN navigation payload. The

equipment was installed in the satellite,

GSAT-4, but, unfortunately, the launch failed

and the GEO satellites never reached its

nominal orbit.

In May 2011, the GSAT-8 satellite carrying a

GAGAN payload was successfully launched

by the Ariane-V launch vehicle of

Arianespace from Kourou, French Guiana.

HISTORY

The first GAGAN transmitter was integrated into

the GSAT-4 geostationary satellite, and had a

goal of being operational in 2008.

Following a series of delays, GSAT-4 was

launched on 15 April 2010, however it failed to

reach orbit after the third stage of

the Geosynchronous Satellite Launch

Vehicle Mk.II that was carrying it malfunctioned.

On 30 December 2013, the Directorate General

of Civil Aviation (DGCA), India certified the GPS

Aided Geo Augmented Navigation (GAGAN)

system

COMMUNICATION NETWORK

IMPACT OF GAGAN FOR AVIATION

Enabler for transition from Ground Based

Navigation to Satellite Based technology

Enable for Performance Based Navigation

Provides platform for harmonized

Ground segment: On the ground, the GPS

data is received and processed in the 15

Indian Reference Stations (INRES),

located at Ahmedabad, Bengaluru,

Bhubaneswar, Kolkata, Delhi, Dibrugarh,

Gaya, Goa, Guwahati, Jaisalmer, Jammu,

Nagpur, Porbandar, Portblair, Trivandrum.

GAGAN APPLICATIONS

Information Systems

Power Grid

Automatic Banking

Precise farming,

dispensing of fertilizers and irrigation

Collision avoidance for railways & real

time application.

En-route and precision approach

for aircrafts Navigational guidance

for Marine services

Help in Fisheries

Mining

Management of Fleet movement

Town planning and road

alignments

BENEFITS

enhanced safety, reduced delays andincreased airport & airspace capacity;

more flexible flight paths;

enhanced surveillance capability;

reduced congestion;

more efficient use of airspace, including moreflexibility

reduce pilot & controller workload.

SAFETY AND EFFICIENCY

Safety and efficiency continue to occupy the

highest priorities in ICAO as they are Strategic

Objectives A and D of the Organization.

Communication, Navigation and Surveillance are

three pillars on which safe Air Traffic Services are

provided over Indian airspace and airports.

The development of air navigation infrastructure is

important as it is critical for “safety of aircraft

operations and capacity enhancements” so that

the booming aviation industry can be sustained

without compromising on safety.

BACKGROUND

The Airports Authority of India manages and

maintains 124 airports .

AAI provides Air Traffic Services (ATS)

consisting of CNS Services and Air Traffic

Management Services with safety over the

designated air spaces.

Communication, Navigation and

Surveillance (CNS) provides backbone for

safe and efficient travel in Aviation sector.

CONCLUSION

India as a member State of ICAO

is taking various measures to bring

in latest technology with a view to

improve the safety of aircraft

operations across the Indian

airspace and be an integral part of

“seamless sky”.
