The Indian Space Research Organisation (ISRO) on Thursday launched the IRNSS-1I navigation satellite, the eighth such satellite to be a part of a constellation, from Sriharikota in Andhra Pradesh.
PSLV-C41/IRNSS-1I Mission blasted off at 4.04 am from the first launchpad at the Sathish Dhawan Space Centre. ISRO officials called it a normal lift-off. IRNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites.
After the successful launch, ISRO Chairman K. Sivan said: “I am extremely happy to announce that the PSLV has precisely injected the navigation satellite in the targeted orbit.”
The Rs. 1,420 crore Indian satellite navigation system – Indian Regional Navigation Satellite System now called NavIC – consists of nine satellites, seven in orbit and two as substitutes.
The 1,425 kg IRNSS-1I will be the second satellite sent up as replacement for IRNSS-1A and the ninth of the IRNSS satellite series.
After 19 minutes, 20 seconds following the lift-off, the rocket will sling IRNSS-1I at an altitude of around 507 km. The launch is the 41st successful launch out of 43.
Each satellite has a life span of 10 years.
