PSLV-C45 lifts off with EMISAT, 28 foreign satellites

India’s latest observation satellite EMISAT took off smoothly on Monday morning with Isro placing payloads in three orbits and conducting space experiments for the first time.
The launch vehicle PSLV-C45 blasted off from the Isro spaceport, Satish Dhawan Space Centre, Sriharikota at 09:27 am today. The rocket is carrying an electronic intelligence satellite Emisat for the Defence Research Development Organisation (DRDO) and 28 third-party satellites. This is the first mission of the PSLV in which its PSLV-QL variant (4 XL Strap-on motors) is being flown. The mission marks several firsts to the credit of the space agency as it would manoeuvre satellites in various orbits and orbital experiments including on maritime satellite applications.
The primary satellite in the rocket is EMISAT, a satellite based on Isro’s Indian Mini Satellite -2 (IMS-2) bus platform. It is an electronic intelligence satellite for DRDO. The mission would witness the Isro placing payloads three orbits and conducting space experiments.
The principal “first-time” innovation this time is the multiple orbits involved in the mission. The main satellite EMISAT and the 28 customer satellites will be ed into two different orbits, and later, the fourth stage engine of the rocket will be taken to a third orbit in space. A new variant of the rocket PSLV-QL equipped with four Strap-On motors in the first stage is used for the launch. Read More
