IRNSS-1F is the sixth navigation satellite from the Indian Regional Navigation Satellite System .
It was placed in geostationary orbit at 32.5 ° East on March 10, 2016 at 10:31 UTC with a PSLV rocket from the Satish Dhawan Space Center rocket launch site.
The configuration of the IRNSS-1F is similar to that of the IRNSS-1A, 1B, 1C, 1D and 1E. The energy supply is provided by two solar cell surfaces with ultra triple junction solar cells that generate around 1660 watts of electrical power and a 90 Ah accumulator . A special thermal control has been implemented for some of the critical elements, such as the atomic clocks on board. The position regulation is controlled with the help of sun and star sensors as well as gyroscopes . The position and trajectory control is carried out with the help of reaction wheels , magnetic gate and twelve engines with 22 Newtons of thrust each. The propulsion system consists of a liquid fuel-powered apogee motor with 440 N thrust.
In addition to the navigation payload, the satellite also carries devices used to measure distances. The navigation payload transmits signals in the L5 and S-band with a bandwidth of 24 or 16.5 MHz, which based on a highly accurate rubidium - atomic clock on board are controlled. A C-band transponder and retroreflectors for laser distance measurement are installed for distance measurement . IRNSS-1F was built on the basis of the I-1K satellite bus and has a planned service life of 12 years.
