Soon after launching from Andhra Pradesh’s Sriharikota, India’s first privately built navigation satellite Indian Regional Navigation Satellite System (IRNSS-1H) has failed. According to ISRO, the heat shield did not separate, which restricted the satellite from getting into the orbit.

ISRO Chief AS Kiran Kumar announced at a press conference that there is no problem in any of the stages but the heat shield has to separate. The satellite got separated internally but is enclosed within the heat shield in the fourth stage. Kumar declared the mission as ‘unsuccessful’.

The IRNSS-1H navigation satellite launch took place at 7:00PM from the Satish Dhawan Space Centre in Sriharikota. However, in about 20 minutes of the launch, the heat shield failed to separate. The satellite was going to be slung into orbit at around 507 km above the earth.

The satellite weighed over 1,400kg, and had been built and tested by ISRO. The system was developed by India along with the US-based GPS. RELATED: ISRO to launch IRNSS-1H navigation satellite today at 7PM: Five facts you should know

The IRNSS-1H was intended to offer services such as terrestrial and marine navigation, disaster management, vehicle tracking, fleet management, navigation for hikers and travelers, and visual, voice navigation for drivers. This navigation system was named “NavIC (Navigation with Indian Constellation) by Prime Minister Narendra Modi. However, given the unsuccessful first attempt, it appears the mission to get an indigenous system into the orbit could be stalled for a while. RELATED: ‘Desi’ GPS to soon become a reality after ISRO signs MoU with CSIR-NPL
