Sriharikota: Indian Space Agency (ISRO) on Thursday launched its sixth navigation satellite IRNSS-1F on board trusted workhorse – Polar Satellite Launch Vehicle — PSLV C32.
The Satellite was launched after the green signal was given by Mission Readiness Review Committee and Launch Authorisation Board.
The satellite has been launched with an objective of providing better navigation services at par with the US-based Global Positioning System.
Designed for a life cycle of 12 years, the satellite has two payloads—one for navigation and the other for ranging.
The navigation payload of IRNSS-1F will transmit navigation service signals to the users. This payload will be operating in the 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 (automatic receivers and transmitters of radio signals) which facilitates accurate determination of the range of the satellite.
The five satellites already launched are IRNSS-1A which was launched on July 1, 2013; IRNSS-1B launched on April 4, 2014; IRNSS-1C launched on October 16, 2014; IRNSS-1D launched on March 28, 2015; and IRNSS-1E that was launched on January 20, 2016.
It is also expected that the ISRO will soon launch its seventh satellite-IRNSS-1G- somewhere in the second half of 2016.
