Answer: GPS Aided GEO Augmented Navigation
Notes: GAGAN stands for GPS Aided GEO Augmented Navigation. The Indian Space Research Organisation (ISROS) developed this indigenous satellite-based GPS augmentation and integrity monitoring system. It provides enhanced navigational accuracy and signal reliability over India and nearby regions. The Autonomous Flying Wing, an unmanned stealth drone vehicle successfully tested by India’s DRDO recently, leveraged GAGAN receivers for autonomous take-off and landing using on-board sensors.
