IRNSS/NavIC: Indigenous Indian Satellite Navigation Programme

Abstract

India has a vibrant space programme, and over years has successfully operationalized communication and remote sensing satellites for the benefit of the country. In order to achieve self-reliance in satellite-based navigation service over Indian region, Indian Space Research Organization (ISRO) has initiated the NavIC (Navigation with Indian Constellation) Programme. NavIC is developed to give PNT (Position, Navigation and Time) services for users over Indian region and its neighbourhood with positional accuracy of 20 m and 10 Nano seconds time accuracy. It provides navigation services to Indian landmass and also it extends its service to 1500 km beyond the geopolitical boundary. This paper provides the overview about the IRNSS and its salient features.
