Sriharikota: Indian Space Research Organisation (ISRO) on Thursday successfully launched the Indian Regional Navigation Satellite System-1I or IRNSS-1I from Satish Dhawan Space Centre on Sriharikota Island.
The satellite was launched with PSLV-C41 rocket at 0404 hrs.
The IRNSS-1I will replace the IRNSS-1A which was rendered ineffective as the onboard atomic clocks had failed.
This is the second attempt by ISRO to send a replacement satellite as on August 2017, the launch of IRNSS-1H failed.
The satellite is part of the constellation of seven NavIC navigation satellite.
