Sriharikota (Andhra Pradesh): The launch of navigation satellite IRNSS-1H by the Indian Space Research Organisation (ISRO) remained unsuccessful, said ISRO Chairman AS Kiran Kumar.
He added, "The rocket heat shield didn't separate. The satellite is inside the heat shield."
The 1,425 kg IRNSS-1H satellite - part of Indian satellite navigation system NavIC or originally called Indian Regional Navigation Satellite System (IRNSS) - was carried by Polar Satellite Launch Vehicle (PSLV) rocket's XL variant on Thursday evening at 7 p.m.
The IRNSS-1H is a replacement for one of the navigation satellites.
Simply put, NavIC is Indian 'GPS'.
At around 7 p.m. the four stage/engine PSLV-XL rocket standing 44.4 metres tall and weighing 321 tonne blasted off from the second launch pad at Sriharikota with a bright orange fire at its tail, lighting up the night sky.
