Indian Space Agency (ISRO) set to launch defence intelligence satellite EMISAT in PSLV-C45

On Monday morning Indian Space Research Organisation (ISRO) would launch a new variant of the rocket Polar Satellite Launch Vehicle (PSLV- C45) that would be carrying an electronic intelligence satellite, EMISAT for the Defence Research Development Organisation (DRDO).

ISRO the countdown for the launch will begin at 6.27 am from Sriharikota in Andhra Pradesh.

Along with the EMISAT, the rocket is suppose to carry 28 third-party satellites and also demonstrate its new technologies of launching satellites in three different orbits.




The ISRO will first put the 436 kilogram EMISAT into a 749 kilometer orbit.

After that, the rocket will be brought down to put 28 satellites into orbit at an altitude of 504 kilometers.

After this, the rocket will be brought down even further to an altitude of 485 kilometers to put three experimental payloads —



  • The Automatic Identification System (AIS) from ISRO for Maritime satellite applications capturing messages transmitted from ships
  • Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation) that’ll assist amateur radio operators in tracking and monitoring position data in India
  • Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) for the structural and compositional studies of ionosphere.

The whole flight sequence will take close to 180 minutes from the rockets lift.

The 28 international customer satellites includle 24 satellites from the US, two from Lithuania and one each from Spain and Switzerland.

ISRO Chairman K. Sivan told news agency IANS — “It is a special mission for us. We will be using a PSLV rocket with four strap-on motors. Further, for the first time we will be trying to orbit the rocket at three different altitudes.”

The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.
