Cartosat 3 Satellite - Variety of Earth Observation Applications

Space Technology plays a huge role in the development of the country through educational, agricultural, communication, and defence sector projects. This article provides information on the Cartosat series of satellites. This is an important topic for students preparing for the UPSC Civil Service Exam and other Government Exams.

Aspirants would find this article very helpful while preparing for the IAS Exam.

A satellite is an artificial object which has been deliberately put into space for different purposes like remote sensing, weather forecasting, image mapping, education, and research. The Indian Space Research Organization (ISRO) is an important body in India and spearheads research in space science in India. Hence, it is an important segment of UPSC Syllabus for the Science and Technology section. 

What is Cartosat?

Designed, developed and built by the Indian Space Research Organization (ISRO), the CARTOSAT satellites are a series of Earth Observation satellites. They were built with the purpose of large-scale mapping of Earth through High-Resolution cameras. 

The CARTOSAT series of observation satellites will aid in detecting changes in natural geographical or man-made features. The Cartosat series is a part of the Indian Remote Sensing Program. They are used for Earth’s resource management defence services and monitoring.

Since the launch of CARTOSAT-1 in 2005, 8 cartosat satellites have been launched by ISRO.

Cartosat-3

Indian Space Research Organization successfully launched CARTOSAT-3 from Sriharikota in November 2019. The Polar Satellite Launch Vehicle (PSLV – C47) carried the CARTOSAT-3 along with 13 other nanosatellites for the US. New Space India Limited (NSIL), the commercial wing of ISRO signed the first commercial order for the launch of the 13 nanosatellites in March 2019.

This was the 74th launch vehicle mission from Sriharikota.

  • It is a Generation- 3 advanced Earth Observation satellite.
  • Cartosat-3 was carried by the Polar Satellite Launch Vehicle (PSLV) – C47, which is a launch system responsible for delivering various IRS Satellites in Low Earth Orbits and is also known as the “Workhorse of ISRO”.
  • CARTOSAT-3 will provide high-resolution images for remote sensing with a ground resolution of 25 cm: it can pick up an object of a minimum of 25 cm size from a height of around 500 km.
    • CARTOSAT-3 became known as the ‘Sharpest Eye’ in civil remote sensing satellites by breaking the record of a US-based satellite WorldView-3 that provided a ground resolution of 31cm.
