ISRO Launches Gagan Satellite Navigation System

[Satellite TODAY 08-16-10] 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.
    The Gagan program is a joint initiative between ISRO and the Airports Authority of India, which said the system would enable airlines to chart direct routes — as they will be less dependent on the ground-based radar systems, save fuel and increase efficiency. The system also would enhance safety features for the airlines by providing services such as precision approach guidance to runways in any weather conditions and increased air-to-air surveillance.
