Isro set launch IRNSS 1H NAVIC PSLV Chennai India.
-Over 1,400 kg spacecraft was built and tested by ISRO
-IRNSS-1H will be a ‘back-up’ navigation satellite for IRNSS-1A.
-IRNSS is regional navigation satellite system developed by India on par with the US-based GPS.
Moving another step forward in the space technology, the Indian Space Research Organisation is all set to launch PSLV-C39 carrying Indian Regional Navigation Satellite System (IRNSS-1H) on Thursday.
ISRO sources here told Deccan Herald that after getting clearance from the Mission Readiness Review (MRR) committee and Launch Authorisation Board (LAB), the countdown of PSLV-C39/IRNSS-1H started at 14:00 hrs today.
The launch will take place at 7 pm on Thursday from the second launch pad of Satish Dhawan Space Centre (SDSC) SHAR at Sriharikota, about 100 km from north Chennai.The 29-hour countdown for the launch of India’s eighth navigation satellite IRNSS-1H began at 2 pm on Wednesday at Sriharikota rocket port.
The satellite will replace one of NAVIC’s seven satellites that is malfunctioning. The 1425 kg IRNSS – 1H satellite will lift off on the back of PSLV, India’s workhorse that will be on its 41st flight.A team of 70 scientists from space research organization ISRO had supervised the entire process. The NAVIC – a system of seven home-made navigational satellites – is currently powering the Swadeshi Global Positioning System. The last of them was launched in April 2016.
But to cover any eventuality, India needed two spare satellites ready for quick launch. That moment came sooner than expected as all three atomic clocks in one of the satellites went out of order in January.
