India's space exploration journey began in the 1970s, spearheaded by the Indian Space Research Organisation (ISRO). The country's efforts have evolved over the decades, starting with early satellite launches to developing sophisticated launch vehicles and regional navigational systems.
Launch vehicles are critical for transporting and deploying satellites or spacecraft into space. India’s development of launch vehicles began in the early 1970s.
IRNSS is an independent regional navigation satellite system designed to provide position accuracy better than 10 meters over India and its surrounding region up to 1500 km. The system offers real-time Position, Navigation, and Time (PNT) services, operational 24/7 under all weather conditions. The IRNSS constellation consists of seven satellites, with software developed indigenously by ISRO. IRNSS provides two services: the Standard Positioning Service, available to all users, and the Restricted Service, an encrypted service for authorized users only.
GAGAN is a satellite-based augmentation system developed in collaboration with the Airports Authority of India (AAI). Its main objectives are to provide accurate satellite-based navigation services for civil aviation and improve air traffic management over Indian airspace.
A GIS is a computer-based tool for mapping and analyzing spatial data. It integrates common database operations like query and statistical analysis with the visual and geographic analysis benefits of maps.
