ISRO chairman: Chances of retrieving satellite still alive


  • Hopeful of retrieving the satellite, the Isro chief said, “Gsat-6A is not out of control and we still hope we can reestablish contact with the satellite.”
  • Dr K Sivan said that Isro knows the approximate location of the satellite in space by using other satellites and other resources.

Dr Sivan said, “Our team is trying to re-establish the communication link with the satellite. Though the delinking of signal from a satellite is a common phenomenon, this time the signal delinking is happening for a longer duration. Even if the satellite’s primary power has failed, we can use the back-up power like solar power if we are able to re-establish the contact with it.”

With a life span of 10 years, the 2,066-tonne satellite, costing Rs 270 crore, was meant to provide mobile communication through multi-beam coverage. The satellite was also significant for the military for communication purposes in remote and border areas. This is because Gsat-6A’s six meter-wide antenna is three times broader than those generally used in communication satellites. The big antenna was meant to enable the satellite to provide mobile communication across the country through handheld ground terminals. In other satellites, smaller antenna require larger ground stations.

On the upcoming launches of navigation satellite IRNSS-1H and Chandrayaan mission, the Isro chief said, “Currently, there is no plan to defer these launches. They will go as per the schedule.” This is the first mission for Dr Sivan, who assumed charge of the space agency in January.
