Another feather in the burgeoning cap of accomplishments of ISRO is the triumphant launch of navigation satellite IRNSS-1G on April 28,2016.The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014, the fourth in March 2015, and the fifth, sixth and seventh on January 20, March 10, and April 28 2016 thus concluding and operationalizing the system . After successfully establishing their mettle globally through Chandrayaan-1 (making India the fourth country to place its flag on the Moon) and Mangalyaan (fourth space agency to reach Mars and the first nation in the world to do so in its first attempt) the navigational satellite setup is truly an incredible masterpiece . With the successful seven-satellite constellation IRNSS (Indian Regional Navigation Satellite System) , India joins a league of elite nations having their own navigation systems in place.
The navigational structure of seven satellites is given a new name by PM Modi as NAVIC (Navigation with Indian Constellation). NAVIC is unique as its regional in nature thus have just seven satellites while other countries have placed more satellites as their system is global in outreach. Even SAARC countries can avail the benefit of NAVIC as it is designed to provide accurate position information to users within the country and 1500km around the Indian mainland thus has foreign policy relevance.
NAVIC would offer services like terrestrial and marine navigation, disaster management, vehicle tracking, fleet management, navigation aide for hikers and travellers, and visual and voice navigation for drivers. NAVIC will provide two types of services, namely, Standard Positioning Services (SPS) to all users, and Restricted Services (RS) to only authorised users. The system has multiple navigation application for defense purposes ranging from autonomous navigational capability to Indian soldiers, sailors and airmen to GPS tipped bombs and missiles.
The magnificent achievement of ISRO made India self reliant and catapulted country's image and wherewithal as second to none.
