GAGAN successfully flight tested: AAI
Recently Airports Authority of India (AAI) has successfully flight tested using GAGAN based ‘Localizer Performance with Vertical Guidance’ (LPV) method.
- India has become the first country in the Asia Pacific region to achieve such a feat in the field of Air Navigation Services (ANS).
- LPV enables aircraft guided methods. These systems are operationally almost identical to the Category 1- Instrument Landing System (Cat-IILS).
- These do not require navigation infrastructure located on land.
- This will provide operational benefits to the aircraft even in inclement weather and low visibility conditions.
GAGAN (GPS Aided GEO Augmented Navigation)
- GAGAN is an Indian Satellite Based Augmentation System (SBAS). It has been jointly developed by the Airports Authority of India and the Indian Space Research Organization (ISRO). It has been developed for India and its neighboring countries in the equatorial region.
- It is one of only four satellite based augmentation systems available in the world.
The other three are: WAAS (United States), EGNOS (Europe) and MSAS (Japan).
Benefits of GAGAN
- Helps in air traffic control to deal with the increase in air traffic. In addition, it improves performance while maintaining security. At the same time, it also reduces the need for necessary infrastructure on the land.
- Manages land transport in India, be it road transport or rail transport.
- Helps farmers by making precision agriculture or aerial spraying of crops possible.
- It is used in forest and wildlife resource management system.
Instrument Landing System:
This is the International Civil Aviation Organization’s (ICAO) standard precision landing assistance system. It is used to guide the aircraft to land on the runway in normal or adverse weather conditions. It provides guidance cues to accurately descend for landing.
