India Launches Electronic Intelligence Satellite – EMISAT from Sriharikota


India made a path breaking venture in the space portfolio on Monday after the launch of an electronic intelligence satellite, EMISAT from the Satish Dhawan Space Centre in Sriharikota by the Indian Space Research Organisation (ISRO).

The 436-kg EMISAT satellite was onboard launch vehicle PSLV-C45 from the second launch pad at Sriharikota at 9.27 AM. The Polar Satellite Launch Vehicle (PSLV) used was a newer variant which onboarded around 28 international nano satellites – 24 from the US, 2 from Lithuana, and one each from Spain and Switzerland.

The 50m tall satellite was placed into its targeted orbit, 17 minutes after its lift off and was placed in a 749 km orbit.

The new variant PSLV-C45 used would be restarted and the fourth engine will be fired up again. The PSLV rocket with four strap-on motors will guide the rocket to orbit at three different altitudes.

Later, the EMISAT on its course will be lowered and stationed at 504 km orbit where it will release the 28-lifted international satellites it carried.

In the further process, the satellite’s last and fourth stage will be reignited again and lowered to 485 kilometres where it will orbit and aid in research and experimentation purpose to the ISRO.

The following experimentation initiatives to be conducted by ISRO are: Automatic Identification System (AIS) for maritime satellite applications, Automatic Packet Repeating System (APRS) to assist AMSAT (Radio Amateur Satellite Corporation) in tracking and positioning of data and thirdly in Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) to study the composition of ionosphere from Indian Institute of Space Science and Technology (IIST).
