ISRO to send IRNSS-1H navigation satellite to space today; countdown begins

The IRNSS-1H is the eighth satellite in the Indian Regional Navigation Satellite System

The countdown begins as the PSLV-C39, which is carrying the 1,425 Kg IRNSS-1H series satellite for navigation-related applications, is all set to be launched from Andhra Pradesh's Sriharikota on Thursday.

The PSLV will launch IRNSS-1H, the eighth satellite of the Indian Regional Navigation Satellite System (IRNSS), into a Sub-Geosynchronous Transfer Orbit (Sub-GTO).

The launch will take place from the Second Launch Pad (SLP) of the Satish Dhawan Space Centre (SDSC) SHAR.

The PSLV-C39, like the previous six launches of IRNSS satellites, will use the 'XL' version of the PSLV that is equipped with six strap-ons, each carrying 12 tonnes of propellant.
