ISRO successfully launches EMISAT defence satellite
With EMISAT another 28 were also launched from Sriharikota space centre
New Delhi: The Indian Space Research Organisation (ISRO) on Monday successfully put into orbit EMISAT defence satellite along with 28 nano satellites of global customers from Sriharikota space centre. The spacecraft is meant to provide electronic intelligence to the Armed Forces is the first of its kind for the country.
The notable aspects of this space mission were the flying of a new variant of the Polar Satellite Launch Vehicle (PSLV); switching off and on the fourth stage engine couple of times; and the use of the fourth stage as an orbital platform carrying three experimental payloads.
The spacecraft took off on the four-stage PSLV-C45 rocket at 9.27 a.m., along with 28 small commercial satellites from the second launch pad at the spaceport of Sriharikota. EMISAT, with its core payload or brain coming from the Defence Research and Development Organisation (DRDO), was released first.
The EMISAT was released into its planned slot from the fourth stage or PS4, 17 minutes into the launch at an orbit 749 km away.
Thereafter, the mission team fired the fourth stage — still carrying the 28 passengers — twice to bring it down to 504 km from Earth.
Today’s launch comes six days after India test-fired an anti-satellite (ASAT) missile in the Mission Shakti operation.
