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.
