EMISAT adds to India’s Defence Capability

After the successful test of A-SAT through Mission Shakti, India’s defence capability has got a further boost with the successful launch of the ElectroMagnetic Intelligence Satellite (EMISAT).


  • EMISAT was jointly developed by ISRO and DRDO, two frontline research agencies of the country.
  • EMISAT will allow India to intercept the radars by detecting the electromagnetic rays from “enemy radar”.
  • EMISAT will cater to India’s strategic defence needs by strengthening the armed forces ability to intercept radar signals and gauge a variety of parameters and understand various details.
  • EMISAT will allow India to know what kind of radar is at work on the other side, based on the spectrum and we will be able to read the distance between the radar and Indian assets too.
  • The satellite has been placed in the Low Earth Orbit (LEO) at an orbit about 700 km from Earth as the objective is to detect low power radar signals. Such radars are typically used to track by low-altitude air-borne vehicles, including aircraft and drones.

The Ministry of Defence had initiated the development of the satellite under the project titled Kautilya, which was first openly acknowledged in 2013-14. But the DRDO has since maintained secrecy about the project.
