India is set to launch its eight navigation satellite IRNSS-1H from Sriharikota in Andhra Pradesh on Thursday. The countdown has begun for the launch of the IRNSS-1H satellite, weighing around 1,425 kilograms (kg), that is scheduled to take off at around 7 pm today. 
 
The satellite will be carried by the Polar Satellite Launch Vehicle (PSLV-C39).

Preparatory work related to the launch is underway, even as propellant filling operations for the four stage/engine PSLV-C39 rocket have been completed. 
 
Since 2013, the Indian Space Research Organisation (Isro) has launched seven navigation satellites. The last one was launched on April 28, 2016.
