IRNSS-1E

IRNSS-1E is the fifth navigation satellite of the seven satellites constituting the IRNSS space segment. Its predecessors, IRNSS-1A, 1B, 1C and 1D were launched by PSLV-C22, PSLV-C24, PSLV-C26 and PSLV-C27 in July 2013, April 2014, October 2014 and March 2015 respectively. IRNSS-1E has a lift-off mass of 1425 kg. The configuration of IRNSS-1E is similar to that of IRNSS-1A, 1B, 1C and 1D.  IRNSS -1E carries two types of payloads – navigation payload and ranging payload. The navigation payload of IRNSS-1E transmits navigation service signals to the users. This payload is 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-1E consists of a C-band transponder which facilitates accurate determination of the range of the satellite. IRNSS-1E also carries Corner Cube Retro Reflectors for laser ranging. PSLV-C31 Successfully launched IRNSS-1E  on January 20, 2016 at 09:31 Hrs (IST) from Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the spaceport of India.
