Cartosat 3 launch: ISRO launched Cartosat-3 satellite along with 13 commercial nanosatellites from the US at 9:28 am IST on November 27, 2019. Cartosat-3 was launched aboard the PSLV-C47 launch vehicle.
The satellites were launched into Sun Synchronous orbit from a launch pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. ISRO had announced the beginning of the 26-hour countdown for the launch of the PSLV-C47 mission on November 26 at 7:28 am.
This is the 21st flight of India’s Polar Satellite Launch Vehicle in 'XL' configuration and 74th launch vehicle mission overall from the Satish Dhawan Space Centre. The PSLV-C47 has 6 solid strap-on motors. The Cartosat 3 satellite will be placed at an orbit of 509 km and inclination of 97.5 degrees.
Cartosat-3 satellite is a third-generation satellite with agile and advanced features including high-resolution imaging capability.
