Question

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?It is designed to provide additional accuracy and integrity.It will allow more uniform and high quality air traffic management.It will provide benefits only in aviation but not in other modes of transportation.Select the correct answer using the code given below.

Accepted Answer

The Indian Space Research Organization (ISRO) and the Airports Authority of India (AAI) have implemented the GAGAN project as a Satellite Based Augmentation System for the Indian Airspace. The primary objective of GAGAN is to establish a certifiable satellite based augmentation system for safety-of-life applications. Statement I is correct: GAGAN is designed to enhance the accuracy and integrity of GPS signals over the Indian airspace. It improves positioning accuracy from about 20 meters to 1–2 meters. Statement II is correct: GAGAN improves navigation reliability, allowing for more uniform and efficient air traffic management, especially in complex or busy airspace. Statement III is not correct: Although developed primarily for aviation, GAGAN also benefits other sectors like railways, road transport, maritime navigation, agriculture, and disaster management.
