IRNSS Constellation

Country: India

Website: IRNSS Constellation

The IRNSS (Indian Regional Navigation Satellite System) constellation has an operational name of NavIC. It is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 Km around it, with plans for further extension. The IRNSS constellation is designed to offer a position accuracy of better than 20 meters in its primary service area, supporting various applications across sectors like military, security, aviation, maritime navigation, disaster management, and civilian services
