The total cost of the mission is about Rs 500 crore and is probably the most expensive and most complex mission to be launched from India till date, says Indian Space Research Organisation (ISRO).
The 321 tonne launcher, in its most powerful configuration, will endeavour to put India's heaviest satellite till date in orbit. Weighing at 1528 kg, the satellite's main purpose will be to monitor crops and forecast floods during the Kharif season, said ISRO.
The project for India's heaviest microwave satellite is being directed by N Valarmathi. She is the second woman to be the satellite project director at ISRO, and the first to head a remote sensing satellite project.
This all-weather surveillance tool is sometimes referred in common parlance as a spy satellite.
India already has another powerful spy satellite called RISAT-2 acquired from Israel and launched using the PSLV in 2009.
