ISRO's control centre for its geostationary and geosynchronous satellites, at Hassan in Karnataka, with a second facility at Bhopal.
MCF monitors and controls all of ISRO's satellites in geostationary and geosynchronous orbits. That includes the INSAT, GSAT, CMS and NavIC satellites.
After launch, MCF carries out the first orbit-raising manoeuvres that move each satellite towards its final slot. It then tests the payload in orbit and runs the satellite for the rest of its life.
Daily work includes tracking, telemetry and commands, station-keeping burns, and managing satellites through eclipse seasons. MCF also recovers satellites when something goes wrong.
Hassan has ten satellite control earth stations with their antennas. Bhopal has three more. During the first days after a launch, MCF also hires ground stations elsewhere in the world.
