- 1. SHARAD INSTITUTE OF TECHNOLOGY COLLEGE OF ENGINEERING, YADRAV A PRESENTATION ON GAGAN NAVIGATION PRESENTED BY Mr. KAJAVE MANISH PRAKASH Mr. V. V Khandare UNDER THE GUIDANCE OF DEPARTMENT OF ELECTRONICS AND TELE-COMMUNICATION ENGG.
- 2. 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
- 3. 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.
- 5. 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
- 7. 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.
- 8. GAGAN APPLICATIONS Information Systems Power Grid Automatic Banking Precise farming, dispensing of fertilizers and irrigation Collision avoidance for railways & real time application.
- 9. 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
- 10. BENEFITS enhanced safety, reduced delays and increased airport & airspace capacity; more flexible flight paths; enhanced surveillance capability; reduced congestion; more efficient use of airspace, including more flexibility reduce pilot & controller workload.
- 11. 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.
- 12. 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.
- 13. 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”.
