IRNSS-1E is the fifth out of seven in the Indian Regional Navigational Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C and IRNSS-1D. It is one among the seven of the IRNSS constellation of satellites launched to provide navigational services to the region. The satellite was placed in geosynchronous orbit. IRNSS-1E has been successfully launched into orbit on 20 January 2016 In 2025, IRNSS-1E was planned to be replaced at its orbital slot of 111.75ºE by NVS-02. However, following the failure of NVS-02, IRNSS-1E will countinue to remain at its slot.
