The CARTOSAT satellite are a series of Indian Optical Earth satellite, built and operated by the Indian Space Research Organisation (ISRO). It is a part of the Indian Remote Sensing Program. They are used for Earth's resource management defence service and monitoring. CARTOSAT satellites are launched by Polar Satellite Launch Vehicle ( PSLV) series. PSLV is an indigenously developed expendable launch system of the ISRO. PSLV is used for delivering various Low Earth Orbits. It is designed mainly to deliver the earth observation or remote sensing satellite with lift-off mass of up to about 1750 kg.
Now, let's talk about the CARTOSAT series in details.
CARTOSAT 1 :-
CARTOSAT 1 was launched by PSLV- C6 on May 5, 2005 from Satish Dhawan Space Centre in Sriharikota. It carries two state-of-the-art panchromatic (PAN) camera that take black and white stereoscopic pictures of the earth in the visible region of the electromagnetic spectrum. The camera is with 2.5m spatial resolution, aquire two images simultaneously. The time difference between the acquisition of the picture by the two camera is about 52 seconds.
CARTOSAT 2 :-
CARTOSAT 2 was launched by PSLV- C7 on January 10, 2007 from Satish Dhawan Space Centre in Sriharikota. It carries a state-of-the-art panchromatic (PAN) camera that take black and white pictures of the earth in the visible region of the electromagnetic spectrum. The data from the satellite is used for detailed mapping and other cartographic applications at CAD-astral level, urban and rural infrastructure development and management, Land Information System (LIS) and Geographical Information System (GIS).
CARTOSAT 2A:-
CARTOSAT 2A was launched by PSLV-C9 on April 28, 2008 from Satish Dhawan Space Centre in Sriharikota along with 9 other satellites. It is a dedicated satellite for the Indian Armed Forces. The satellite carries panchromatic (PAN) camera that take black and white pictures in the visible region of electromagnetic spectrum.
CARTOSAT 2B :-
CARTOSAT 2B was launched by PSLV-C15 on July 12, 2010 from Satish Dhawan Space Centre in Sriharikota. The satellite carries a panchromatic (PAN) camera capable of taking black and white pictures in the visible region of electromagnetic spectrum.
CARTOSAT 2C :-
CARTOSAT 2C was launched by PSLV-C34 on June 22, 2016 from Satish Dhawan Space Centre in Sriharikota. The features of this satellite include the use of adative optics, weather mapping, cartography, etc.
CARTOSAT 2D :-
CARTOSAT 2D was launched by PSLV-C37 on February 15, 2017 from Satish Dhawan Space Centre in Sriharikota.
CARTOSAT 2E :-
CARTOSAT 2E was launched by PSLV-C38 on June 23, 2017, along with 30 other nano satellites.
CARTOSAT 2F :-
CARTOSAT 2F was launched by PSLV-C40 on January 12, 2018 along with 30 nano satellites from India, Canada, Finland, France, Republic of Korea, UK and the USA.
CARTOSAT 3 :-
CARTOSAT 3 satellite is a third generation advanced Indian Earth observation satellite, built and operated by ISRO. It has a panchromatic (PAN) camera resolution of 0.25 m, this means it can pick up an object of a minimum of that size from a height of around 500 km. The satellite was placed in an orbit of 509 km at an inclination of 97.5 degree. PSLV-C47 launched CARTOSAT 3 and 13 commercial nano satellites into Sun Synchronous Orbit on November 27, 2019 from Satish Dhawan Space Centre in Sriharikota. The launch mass of CARTOSAT 3 is 1,625 kg and it's mission duration is 5 years. According to ISRO, 12 of the US nano satellites, named as FLOCK-4P are earth observation satellites and the 13th is called MESHED, a communication test bed satellite.
Mr. Sivan said "CARTOSAT 3 is the Indian highest resolution civilian satellite and the most complex and advanced earth observation satellite ISRO has built so far".
I would like to thank ISRO official website, Wikipedia and study iq for helping me to get all the informations and I would like to congratulate Team ISRO for this enormous achievement.
Thank You.
