India launches eighth navigation satellite

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.
