ISRO Launches Gagan Satellite Navigation System

The Indian Space Research Organization (ISRO) has launched the GPS-supported Geo Augmented Navigation (Gagan) satellite navigation system to aid Indian air traffic, the organization announced Aug. 12.

Gagan, based on a constellation of 24 satellites positioned in six different orbital locations, aims to provide seamless coverage of air traffic from South Asia to Africa and connect to the systems of Europe and Japan. It is expected to enhance marine and transport navigation, search and rescue operations, survey, and mapping.

At present, only the United States, European Union and Japan have such a system. "This system is expected to provide enhanced navigation performance for critical applications like civil aviation, marine navigation, train and road transport," said a ministry official.

Gagan is a joint initiative of the Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO).

The system provides enhanced safety features for the airlines as they would be able to have precision approach guidance towards runways in any weather conditions, the officials said. It will also increase air-to-air surveillance.
