Applications of Cartosat-3

It will address the increased user’s demands for large scale urban planning, rural resource and infrastructure development, coastal land use and land cover etc.

About International Customer Satellites

As discussed above that 13 Commercial Nano-satellites from the USA are flown with Cartosat-3 onboard PSLV-C47.

- These commercial satellites are being launched under commercial arrangements with NewSpace India Limited (NSIL) which is the commercial arm of India Space Research Organisation (ISRO).

About PSLV

The full form of PSLV is Polar Satellite Launch Vehicle. It is the third generation of the launch vehicle of India. It is in a category of medium-lift launchers with a reach up to several orbits, including the Geo Synchronous Transfer Orbit, Lower Earth Orbit, and Polar Sun Synchronous Orbit. PSLV has a four-stage system consisting of solid and liquid-fuelled rocket stages.

PSLC-C47 is the 21st flight of PSLV in the 'XL' configuration consisting of 6 solid strap-on motors.

Note: After losing the contact with Chandrayaan-2's Vikram Lander on 7 September, 2019, it is ISRO's first launch. Originally launch of Cartosat-3 was planned in 2014 onboard PSLV.
