IRNSS-1F is the sixth navigation satellite out of seven in the Indian Regional Navigational Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D and IRNSS-1E. The satellite is one among the seven of the IRNSS constellation of satellites launched to provide navigational services to the region.[3]


It was launched aboard a PSLV-XL rocket bearing flight number C32 and was successfully put into geosynchronous orbit at 1601 hrs IST on 10 March 2016.[4][5]


The satellite carries two types of payloads. The navigation payload transmit navigation service signals to users and ranging payload consists of C-band transponder that facilitates accurate determination of the range of the satellite.[3]

It carries Corner Cube Retro Reflectors for laser ranging.[6]

IRNSS-1F has a 12-year mission life.[2]
