BACKGROUND
 The Airports Authority of India manages and
maintains 124 airports and civil enclaves.
 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.

Seamless sky
 Aviation and avionics data has to be shared
worldwide.
 The Indian airspace has to be an integral part of
the modern airspace scenario.
 The world of modern airspace has to be seamless
for civil aviation; such are the exacting
requirements, regardless of the political
boundaries that lie thousands of feet below,
irrespective of the large oceanic space that separate
continents.
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.
Satellite based Navigation
 Technologies are changing at a faster pace. Gone are
the days when an isolated Radar or a few ILSs would
suffice.
 New technologies practices and procedures are coming
up to address the challenges being thrown in air travel
world over and especially in India.
 The facilities have to be the latest and India will have to
keep pace with the latest requirements matching with
the modern day airborne equipage.
Satellite based Navigation..
 All this translates into increased use of Satellite
based Navigation and Surveillance technologies.
 We in India are progressing towards achieving
the “Global Plan Initiatives”, the bed rock of
ICAO dream towards “seamless sky”, in tune
with the rest of the world.
 It is only then that traffic volumes of high
densities can be handled efficiently, smoothly to
stringent safety requirements.
Global Navigation Satellite System (GNSS)
 ICAO Member States have
also endorsed
Global Navigation Satellite System (GNSS) as
the future navigation system for civil aviation.
 The face of technology and equipments what
we are using today for air navigation are likely
to be replaced with Global Navigation
Satellite
System
(GNSS)
augmentation systems.

Why next Generation ATS
 The future ATM systems will use Automatic Dependent Surveillance
Broadcast (ADS-B), other data link applications, Satellite
Communications, Global Navigation Satellite Systems (GNSS) and
weather data to integrate ground-based automation and airborne
flight management systems.
 The future ATM system will make maximum use of automation to
reduce or eliminate constraints imposed on ATS operations by
current systems.
 ATM automation will make it possible to formulate real-time flow
management strategies and allow for negotiation between ATS and
aircraft.
 It will significantly benefit the rapidly growing air traffic operations
like
flexible flight routes, less carbon emission, while
accommodating increased capacity.
Key Elements of technology upgrade for NextGen
COM Transition from Voice to Data Communication.
Digital communication – through satellite
voice as a back up when complete data communication is
used back
NAV Satellite based Navigation System complimented with

GAGAN (GPS Aided Geo Augmented Navigation) to
support Satellite Navigation
The ground based navigation equipments retained as a
back‐up
Radars would continue to be primary surveillance
equipment in high density traffic and terminal approach
areas.
The upcoming technologies in surveillance, ADS-B and
wide area multilateration to be used in combination to
provide augmented surveillance capability
Surveillance over oceanic areas through ADS-CPDLC
WORLD WIDE TREND IN GNSS IMPLEMENTATION
 Traditional navigation systems are ground based which have site
limitations and range problems
 ICAO Member States endorsed Global Navigation Satellite System
(GNSS) as the Future Air Navigation (FAN) System for seamless
navigation in 1993.
 Wide Area Augmentation System (WAAS-USA) is the first certified
SBAS system operational from July 2003.
 Multi-Satellite Augmentation System –(MSAS-Japan) is certified
for aviation use from September 2007.
 European Geo-stationary Navigational Overlay Service –EGNOS
(Europe) has received certification for aviation use with effect from
July 12, 2010.
 GPS Aided GEO Augmented Navigation – GAGAN (India) Prestigious
project for India is expected to be certified by June 2013.

Next Generation Systems-SESAR
 Single European Sky ATM Research is the name given to the
project which will overhaul the European airspace
 KEY FEATURES:
 the network operation plan, a dynamic rolling plan for
continuous operations that ensures a common view of the network
situation;
 full integration of airport operations as part of ATM and the
planning process;
 trajectory management, reducing the constraints of airspace
organisation to a minimum;
 new aircraft separation modes, allowing increased safety,
capacity and efficiency;
 system-wide information management (SWIM), securely
connecting all the ATM stakeholders which will share the same
data;
 controllers and pilots to be assisted by new automated functions to
ease their workload.
Next Generation Systems…
Next Generation Air Transportation System
(NextGen) is the name given to new National
Airspace System due for implementation across
the United States in stages between 2012 and
2025.
This transformation has the objective of reducing
gridlock, both in the sky and at the airports.
Pilots in the aircrafts and air traffic managers on
the ground will have the same
information, transmitted via data
communications.

Augmented
 ISRO and the AAI are implementing the GAGAN project as a
Satellite Based Augmentation System for the Indian Airspace.
GAGAN is a prerequisite for implementation of NextGen
Systems for India.
It will revolutionize navigation in India, be it over land or
sea.
Its implementation will allow more direct routings,
multiple approaches, fuel savings and provide for
capacity enhancement of airports and airspace.
BENEFITS OF NEXT GEN ATM SYSTEMS
 enhanced
safety, reduced delays
increased airport & airspace capacity;
and
 more flexible flight paths;
 enhanced surveillance capability;
 reduced congestion;
 more efficient use of airspace, including more
flexibility and reduced separations;
 enhanced meteorological information; and
 reduced pilot & controller workload.
NEXT STEPS
As there will be many manufacturers/suppliers for
the Next Gen Systems/Tools in near future, CNS
Directorate may revisit its procurement processes
to get the quality product at competitive prices.
CNS Directorate should have its Procurement
Manual as a reference guide for its Capital and
Maintenance procurements at CHQ and Field
