India is creating history every year by launching satellites of many other countries along with its own. On 1 April, 2019; India launched the EMISAT in Sun Synchronous Polar Orbit.
The full form of EMISAT is "Electronic Intelligence Satellite". It was made by ISRO and DRDO together. EMISAT was launched by PSLV C-45 launch vehicle. EMISAT was launched from Satish Dhawan Space Center, Sriharikota.
It is worth to mention that Polar Satellite Launch Vehicle (PSLV) has been used in the two major missions of India i.e. Chandanayan in 2008 and Mars Mission in 2013.
Objectives of the Mission: EMISAT aims to monitor electronic or any kind of human or terrorist activity on the India – China or India Pakistan border.
EMISAT satellite will monitor the radar and the sensor on the border. This satellite will be used not only for human but for any kind of activity related to communication.
So the satellite will measure the electromagnetic spectrum. This satellite will help the DRDO in conducting the Defense Research.
Hence EMISAT can be termed as “Spy in the Sky.”
PSLV rocket with EMISAT has taken 28 satellites from other countries, including 24 US, two from Lithuania and one satellite each from Spain and Switzerland. These foreign satellites were launched as part of commercial arrangements.
The 28 international customer satellites together weighing about 220 kgs while EMISAT weight around 436 kg alone.
According to ISRO, PSLV rocket placed EMISAT in a 749-kilometer orbit, after this, 28 other satellites were placed at the 504 km orbit.
It is worth to mention that around 1000 peoples watched this live and the government of India is planning to make a stadium so that people can sit there and watch the launch of any satellite live.
It is known that in the world so far, the US Agency, NASA allows common people to see the live launch of many satellites.
Facts about the PSLV:
Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. The first flight of the PSLV was launched on the September 20, 1993 but first successful launch was in October 1994.
PSLV have launched 39 consecutively successful missions by June 2017.
During 1994-2019 periods, the vehicle has launched 47 Indian satellites, 297 satellites for customers from abroad and 10 satellites built by students from Indian Universities.
Besides, the vehicle successfully launched two spacecraft – Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013.
In its next mission, PSLV-C46 will launch RISAT-2B in May 2019.
It is expected that in the coming years, ISRO will launch more number of satellites and continue to glorify India's name in the world of satellites.
