IRNSS-1H News

ISRO officials say they strongly suspect the failure of pyro elements for the non-separation of the heat shield of its rocket PSLV's XL variant on August 31.

Satellites are housed atop the rocket and covered by a heat shield or payload fairing, which protects them from getting burnt when the rocket crosses the atmosphere.

This satellite will serve as a replacement to the IRNSS-1A, all three of whose atomic clocks have failed.

The spacecraft was built and tested by ISRO along with a consortium of six small and medium industries.

Today, the Indian space agency is all set to launch its eighth navigation satellite – the IRNSS-1H – as a spare or back-up for its constellation in the geo-orbit.

The IRNSS-1H was built by a consortium led by Bengaluru-based Alpha Design Technologies under the supervision of a team consisting of 70 scientists from ISRO.

The 1,425-kg satellite is all set to start its journey from the second launch pad of the Satish Dhawan Space Centre at Sriharikota, riding space organization's trusted launch vehicle PSLV-XL

Indian Space Research Organisation (ISRO) will launch its first private sector-built navigation satellite IRNSS-1H from the Satish Dhawan Space Centre at Sriharikota on Thursday at 7 PM. 

The 1.4-tonne satellite will be launched aboard the PSLV-C39 rocket on Thursday, August 31, from the state-run Indian Space Research Organisation's (ISRO) spaceport at Sriharikota off the Bay of Bengal in Andhra Pradesh, about 80 km northeast of Chennai at 7:00 pm.
