What: IRNSS-1I
When: April 12, 2018
How: From PSLV-C41
- ISRO’s Polar Satellite Launch Vehicle PSLV-C41 successfully launched the 1,425 kg IRNSS-1I Navigation Satellite on April 12, 2018 from Satish Dhawan Space Centre SHAR, Sriharikota.
- It was PSLV’s forty third (43rd) flight.
- PSLV-C41 lifted off at 0404 hrs (4:04 am) IST, as planned, from the First Launch Pad.
- After a flight lasting about 19 minutes, the vehicle achieved a Sub-Geosynchronous Transfer Orbit with a perigee (nearest point to earth) of 281.5 km and an apogee (farthest point to earth) of 20,730 km inclined at an angle of 19.2 degree to the equator following which IRNSS-1I separated from PSLV.
- IRNSS-1I is the latest member of the ‘Navigation with Indian Constellation (NAVIC)’ system. NAVIC, also known as Indian Regional Navigation Satellite System (IRNSS), is an independent regional navigation satellite system designed to provide position information in the Indian region and 1,500 km around the Indian mainland.
- A number of ground facilities responsible for IRNSS satellite ranging and monitoring, generation and transmission of navigation parameters, satellite control, network timing, etc., have been established in many locations across the country as part of NavIC.
- Till now, PSLV has successfully launched 52 Indian satellites and 237 customer satellites from abroad.
