(a) Thumba – Kerala

(b) Hassan – Karnataka

(c) Sriharikota – Andhra Pradesh

(d) Hyderabad– Andhra Pradesh

The correct answers to the above question in:

Answer: (b)

The Master Control Facility is a facility set up by the Indian Space Research Organisation (ISRO) in the city of Hassan in the Indian state of Karnataka. Established in 1982, this facility is responsible for monitoring and controlling the satellites launched by ISRO.

This was the only Master Control Facility of ISRO till another one was established in Bhopal in 2005. When ISRO wanted a control facility, it inspected various sites that were offered to it within India. ISRO chose Hassan as the location (Location on Google Maps) because it was free of noise and encountered less terrestrial transmission than other proposed sites.

Low interference was a must since the facility should be able to pick up even very weak signals from the satellite. Currently MCF controls the following 10 satellites: INSAT-2E, INSAT-3C, INSAT-3A, INSAT3E, INSAT-4A, INSAT-4B, INSAT-4CR KALPANA-1, GSAT-8 and GSAT-12.

On these 10 satellites, 8 are controlled from MCF Hassan and two are controlled from MCF Bhopal (INSAT-3C and INSAT-4CR.)
