Nellore: The 48 hour long countdown activity of Polar Satellite Launch Vehicle-C31/Indian Regional Navigation Satellite System (IRNSS-1E) Mission has started at 9:31 AM on Monday at Satish Dhawan Space Centre, Shar. The propellant filling operations are in progress.
The launch will take place at 9.31 am on January 20 from the Second Launch Pad (SLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. In its 33rd flight), Polar Satellite Launch Vehicle (PSLV-C31), will place IRNSS-1E, the fifth satellite of the Indian Regional Navigation Satellite System (IRNSS), in Geosynchronous Transfer Obit (GTO) with 284 km perigee (nearest point to earth) and 20,657 km apogee (farthest point to earth) with an inclination of 19.2 degress with respect to the equatorial plane.
After injection into this preliminary orbit, the two solar panels of IRNSS-1E will be automatically deployed in quick succession and the Master Control Facility (MCF) at Hassan will take control of the satellite and perform the initial orbit raising manoeuvres. The configuration of IRNSS-1E is similar to its predecessors IRNSS-1A, IB, IC and ID. The launch will take place at 9.31 am on January 20 from the Second Launch Pad (SLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.
