ISRO’s Polar Satellite Launch Vehicle (PSLV), in
its 47th mission (PSLV-C45) has launched EMISAT, from Satish Dhawan Space
Centre, Sriharikota in coastal Andhra Pradesh. EMISAT is India’s first electronic
EMISAT is a satellite built around ISRO’s Mini
Satellite-2 bus weighing about 436 kg. It has been jointly developed by ISRO
and Defence Research and Development Organization (DRDO). It has been developed
under DRDO’s Project Kautilya which aims to boost India’s space surveillance
The satellite is intended for electromagnetic
spectrum measurement. It will provide location and information of hostile
radars and sensors deployed along the Indian borders. It will also help in
knowing exact topography of enemy areas and detect communication devices active
in an area.
Space-based electronic intelligence or ELINT
from the EMISAT is an addition to India’s current land or aircraft-based ELINT,
and will help India’s intelligence agencies better monitor hostile activities
in border areas.
The PSLV-C45 mission has marked several “firsts”
for ISRO. For the first time, ISRO has placed the satellites and payloads in
three different orbits. A new variant of the rocket, PSLV-QL, with four
strap-on boosters has been used for the launch for the first time. It is also
the first time PSLV fourth stage (PS4) used solar panels to support payloads
hosted on it.
