IRNSS 1F Sixth Navigation Satellite Launched Sucessfully




March 10, 2016 – Polar Satellite Launch Vehicle, in its thirty-fourth flight (PSLV-C32), launches IRNSS-1F, the sixth satellite of the Indian Regional Navigational Satellite System (IRNSS).

IRNSS-1F was launched into a sub-Geosynchronous Transfer Orbit (sub-GTO) on March 10, 2016 at 16:01 hrs (IST) from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.

This is the thirty-third consecutively successful mission of PSLV and the twelfth in its ‘XL’ configuration, earlier eleventh being PSLV-C11/Chandrayan-1, PSLV-C17/GSAT-12, PSLV-C19/RISAT-1, PSLV-C22/IRNSS-1A, PSLV-C25/Mars Orbiter Spacecraft, PSLV-C24/IRNSS-1B, PSLV-C26/IRNSS-1C, PSLV-C27/IRNSS-1D, PSLV-C28/DMC3, PSLV-C30/ASTROSAT and PSLV-C31/IRNSS-1E missions.

The first five satellites of the IRNSS series namely IRNSS-1A, 1B, 1C, 1D and 1E were launched in July 2013, April 2014, October 2014, March 2015 and January 2016 respectively.

The seventh and last satellite in this series is expected to be launched in the second half of the year and will help in providing accurate positional information to the Indian users.

IRNSS -1F carries two types of payloads – navigation payload and ranging payload. The navigation payload of IRNSS-1F will transmit navigation service signals to the users. This payload will be operating in L5 band and S band. A highly accurate Rubidium atomic clock is part of the navigation payload of the satellite. The ranging payload of IRNSS-1F consists of a C-band transponder, which facilitates accurate determination of the range of the satellite. IRNSS-1F also carries Corner Cube Retro Reflectors for laser ranging.
