GPS-Aided Geo Augmented Navigation (GAGAN) uses a system of ground stations to provide necessary augmentation. Which of the following statements is/are correct in respect of GAGAN?
I. It is designed to provide additional accuracy and integrity.
II. It will allow more uniform and high-quality air traffic management.
III. It will provide benefits only in aviation but not in other modes of transportation.
Select the correct answer using the code given below:
Explanation
Statement I is correct. GAGAN (GPS-Aided Geo Augmented Navigation) enhances the accuracy and integrity of GPS signals through a system of ground reference stations and geostationary satellites. It is designed to meet the precision needs of safety-critical navigation, especially in aviation.
Statement II is correct. GAGAN improves the quality and uniformity of air traffic management across Indian airspace by enabling better route optimization, approach procedures, and reduced separation between aircraft.
Statement III is not correct. While GAGAN was primarily developed for aviation, its services are beneficial in other sectors too, such as railways, maritime navigation, highways, surveying, and disaster management.
