India’s space agency ISRO on Saturday said it will launch a navigation satellite from its spaceport in Sriharikota in Andhra Pradesh on Thursday.

“The 43rd flight of Polar Satellite Launch Vehicle (PSLV-C41) will launch the Indian Remote Navigation Satellite System (IRNSS-1I) from the initial launch pad of the Satish Dhawan Space Centre at Sriharikota on April 12 at 4.04am,” the Indian Space Research Organisation (ISRO) said in a statement on its official website.

The IRNSS-1I may be the eighth satellite to join the NavIC navigation satellite constellation in Earth’s polar orbit.

The launch a fortnight after ISRO launched communication satellite GSAT-6A on March 29 aboard a heavy rocket (GSLV), but lost communication link with it on March 31 when it was on course to its intended slot in the geostationary orbit, about 36,000km above the Earth.

The Master Control Facility (MCF) of the room agency at Hassan in Karnataka has been trying its best to displace link with the 2,000kg satellite since April 1 however not succeeded till date.

The 8th navigation satellite IRNSS-1I will be a replacement in the NavIC constellation for the 1,425kg IRNSS-1H that didn’t eject out from the PSLV rocket on August 31, 2017 to its intended orbit as its heat shield failed to separate even about 20 minutes after it was launched.
