Prime Minister Narendra Modi has spoken to the scientists at Indian Space Research Organisation (ISRO) to personally congratulate them on successful launch of PSLV C31 and precisely putting IRNSS 1E in the designated orbit.
"Congratulating the dynamism and determination of ISRO and our scientists on successful launch of PSLV C31 and putting IRNSS 1E in orbit precisely. Spoke to the scientists at ISRO and congratulated them on their accomplishment today. Our scientists keep making us proud", the Prime Minister tweeted.
After the PSLV-C31 lift-off at 0931 hrs (9:31 am) IST from the Second Launch Pad, it took about 18 minutes 43 seconds for IRNSS-1E Satellite to be injected to an elliptical orbit of 282.4 km X 20,655.3 km inclined at an angle of 19.21 degree to the equator (very close to the intended orbit) and successfully separated from the PSLV fourth stage.
After injection, the solar panels of IRNSS-1E were deployed automatically. ISRO’s Master Control Facility at Hassan, Karnataka took over the control of the satellite.
In the coming days, four orbit manoeuvres will be conducted from Master Control Facility to position the satellite in the Geosynchronous Orbit at 111.75 deg East longitude with 28.1 deg inclination.
IRNSS-1E is the fifth of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland.
Eighteen ground stations have been established across the country to monitor the satellites. In the coming months, the remaining two satellites of this constellation, namely, IRNSS-1F and IG, are scheduled to be launched by PSLV, thereby completing the entire IRNSS constellation.[category, science] [tags, isro, pslv c31, launch, pm, congratulation, message,]
