  • After separation, the solar panels of IRNSS-1I were deployed automatically. ISRO’s Master Control Facility (MCF) at Hassan, Karnataka took over the control of the satellite.
  • In the coming days, orbit manoeuvres will be performed from MCF to position the satellite at 55 deg East longitude in the planned Geosynchronous Orbit with an inclination of 29 deg to the equator.
  • 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 and1500 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.
