Another quantum leap for Indian Space Research Organisation; launches EMISAT satellite along with 28 nano satellites of global customers  on board PSLV C 45 from Sriharikota; EMISAT is India's latest observatory satellite.

As the 27-hour countdown concluded, the nearly 50-metre tall rocket, a new variant of ISRO's trusted work horse PSLV-QL, blasted off from the second launch pad at the spaceport of Sriharikota, about 125 km from Sriharikota at 9.27 am. The EMISAT satellite is aimed at electromagnetic measurement. The EMISAT is India's latest observatory satellite.

On the successful launch of PSLV C 45, the ISRO chairman K Sivan has said that it is now marching towards the 485km orbit to do its function as an orbital platform for experiments. He thanked the team members for making the mission a success.

Prime Minister Narendra Modi  congratulates space scientists and ISRO for their achievement on  PSLV C45 launch; He tweeted: Congratulations to the scientists at ISRO for the successful PSLV C-45 launch which has put our EMISAT satellite and 28 satellites from 4 countries (USA, Switzerland, Lithuania, Spain) in their respective orbits.

This complex mission involved first flight of PSLV-QL variant with 4 strap-on motors and the entire mission was carried out in 3 different orbits. India provides reliable launch services for even increasingly complex missions.


India's PSLV-C45 successfully injected EMISAT and 28 international customer satellites into their designated orbits.

The PSLV-C45 lifted off at 09:27 Hrs (IST) on April 01, 2019 from the second launch pad of Satish Dhawan Space Centre SHAR, Sriharikota in its 47th flight. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors.

About 17 minutes and 12 seconds after lift-off, EMISAT was successfully injected into intended sun-synchronous polar orbit of 748 km height.

After the separation of EMISAT, the vehicle’s fourth stage engines were restarted twice to place the 28 international customer satellites precisely into a sun-synchronous orbit of 504 km height. The last customer satellite was placed in its designated orbit 1 hour and 55 minutes after lift-off.

About 3 hours after lift-off, the fourth stage (PS4) of the vehicle was moved to a lower circular orbit of 485 km after two restarts to establish it as an orbital platform for carrying out experiments with its three payloads. The PS4 payloads are Automatic Identification System from ISRO, Automatic Packet Repeating System from AMSAT, India and Advanced Retarding Potential Analyzer for ionospheric studies from Indian Institute of Space Science and Technology.
