Q. 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?

Explanation : 

Statement I: It is designed to provide additional accuracy and integrity.

This statement is correct. GAGAN (GPS Aided GEO Augmented Navigation) is a Satellite-Based Augmentation System (SBAS) whose primary objective is to enhance the accuracy, availability, and integrity of GPS signals for civil aviation applications. It provides corrections to GPS signals, leading to improved positional accuracy and ensuring the reliability and trustworthiness of the navigation information.

Statement II: It will allow more uniform and high quality air traffic management.

This statement is correct. GAGAN provides increased accuracy in position reporting, which in turn leads to more uniform and high-quality Air Traffic Management (ATM). This modernization of airspace can result in reduced flight delays, fuel savings, and improved flight safety.

Statement III: It will provide benefits only in aviation but not in other modes of transportation.

This statement is incorrect. While GAGAN was primarily developed for civil aviation, it provides benefits beyond aviation to various other modes of transportation and services. These include maritime, highways, railways, defense services, security agencies, telecom industry, and personal users of position location applications, including precision farming. For example, it can be used for railway signaling, anti-collision devices in railways, road asset management, and even for identifying wildfires.

Therefore, statements I and II are correct.
