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.

Correct Option: I and II only

Statements I and II are correct, while Statement III is incorrect. GAGAN (GPS-Aided Geo Augmented Navigation) is a Satellite-Based Augmentation System (SBAS) designed to provide critical augmentation to GPS, offering additional accuracy, availability, and integrity required for civil aviation (Statement I is correct). It enables seamless and uniform air traffic management across the Indian airspace (Statement II is correct). However, Statement III is incorrect because although originally designed for aviation, GAGAN's signals and augmentation benefits are increasingly utilized across multiple transport sectors such as railways, highways, maritime navigation, and surveying.
