Indian Space Research Organisation (ISRO) will launch 29 satellites including the primary payload EMISAT, on the first of April.
Polar Satellite Launch Vehicle, PSLV-C45 will take off from Satish Dhawan Space Centre in Sriharikota tentatively at 9:30 AM carrying the satellites onboard. EMISAT has been developed for monitoring radar network by India. An ISRO release says, EMISAT, weighing 436 kg, is intended for electromagnetic spectrum measurement. It will be placed in an orbit of about 753 km altitude. The customer payloads are from Lithuania, Spain, Switzerland and the US. They will be hurled into space at an altitude of about 505 km.
After all the satellites are put into orbits, the fourth stage of the rocket will be propelled to a different elevation and will be used as a platform for different experiments by Indian institutions, including ISRO. Indian Institute of Space Science (IISc) and the Radio Amateur Satellite Corporation are the other two institutions that will have their devices on the experimental platform. Normally the rocket engine is left redundant as space debris once the launch mission is over. But ISRO uses it for such experiments for the second time in a series. During the last PSLV mission also it adopted the same innovative method.
