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:
Statements I and II are correct. GAGAN is a Satellite-Based Augmentation System (SBAS) designed to provide improved accuracy, integrity, and availability of GPS signals, which enhances air traffic management. Statement III is incorrect because GAGAN's applications extend beyond aviation to various other sectors like railways, maritime, surveying, agriculture, and disaster management. Therefore, I and II are correct.
