Cartosat series
 

Cartosat-3 is an advanced Indian Earth Observation satellite built and developed by ISRO, which will replace the IRS series. It has a panchromatic resolution of 0.25 metres making it the imaging satellite with highest resolution in the world and Mx of 1 metre with a high quality resolution which is a major improvement from the previous payloads in the Cartosat series.[3][4][5]

Potential uses include weather mapping, cartography or defence, and strategic applications.[6]

Overview

Cartosat-3 has a resolution of 25 cm (10").[7] It uses 1.2 m optics with 60% of weight removal compared to Cartosat-2. Other features include the use of adaptive optics, acousto optical devices, in-orbit focusing using MEMs and large area-light weight mirrors and advanced sense with a high quality resolution.[8] It has a planned mission life of 5 years.[9]

History

Cartosat-3 is the 3rd generation of high-resolution imaging satellites developed by ISRO.[10] It was developed in response to increased demand for imaging services to address urban planning, rural resource and infrastructure development needs.[11]

Launch

PSLV C47 lifting off from Second Launch Pad with Cartosat-3.

PSLV C47 carrying Cartosat-3 was launched on 27 November 2019 at 03:58 UTC using XL variant of Polar Satellite Launch Vehicle from the second launch pad of Satish Dhawan Space Centre into a sun synchronous orbit of 509 kilometers. Thirteen commercial ride-sharing 3U cubesats including twelve SuperDoves (Flock 4p)[12] by Planet Labs and one Meshbed by Analytical Space of United States were also put in orbit using the same launch vehicle.[9][13] Commercial ride-share was arranged by New Space India ltd, Spaceflight industries and ISILaunch.[14][15]
