The PSLV took off at 2234 GMT (6:34 p.m. EDT) with a rush of flame from a solid-fueled core motor and four strap-on solid rocket boosters.
PSLV-C41/IRNSS-1I Mission blasted off at 4:04 am from the first launchpad at the Sathish Dhawan Space Centre. The satellite will be launched at 4.04am on Thursday from Sriharikota by PSLV-C41. Indian Standard Time on Thursday.
He added as the IRNSS system consist a constellation of seven satellites each of which have to be put in a designated location.
In August past year, the previous mission of a PSLV carrying IRNSS-1H failed after the heat shield covering the satellite failed to separate.
The mission is the 43rd flight of the PSLV rocket and the 20th flight of the PSLV-XL version. The second stage's Vikas engine will carry the rocket out of the atmosphere, at which point the heat shield that protected the satellite through layers of air will separate to reduce weight, at 113 km. This mission has again proved to be fastest launch in the history of the organization. The satellite was launched astride GSLV-F08 launch vehicles.
The IRNSS 1I satellite mounted on top of the Polar Satellite Launch Vehicle. The Indian Air Force is expected to switch from Global Positioning System to IRNSS when it is deemed fully functional and transponders required to receive IRNSS signals are available.
IRNSS is an independent regional navigation satellite system created to provide position information in the Indian region and 1,500 km around the Indian mainland.
Indian engineers have been unable to restore communications with GSAT 6A. He said, "Currently, two teams are working simultaneously in Isro". "The baby has been delivered, and it's unfolded its solar arrays".
Payloads: Like its other IRNSS predecessors, IRNSS-1I also carries two types of payloads - navigation payload and ranging payload. It has a geo-synchronous orbit at an inclination of 29 degrees once in place over the 55 degree east longitude.
The IRNSS-1L, the backup navigation satellite with a new atomic clock has been developed under ISRO but it was actually developed by small-sized firms which were lead by Bengaluru-based Alpha Design Technologies.
