Cartosat-3 is a series of ultra-high-resolution (up to 25 cm) satellites that complement the opto-electronic intelligence and dual-purpose remote sensing satellite systems created in India, developed as a continuation of the Cartosat-2 series of Earth observation satellites. The new spacecraft have improved spatial characteristics. Shooting is performed in panchromatic, multispectral and hyperspectral modes. In 2020, it is also planned to launch two similar devices Cartosat 3A and 3B. At the moment, data from the satellite has not yet been launched for commercial use, because the satellite is still undergoing the calibration stage. However, the first images obtained are striking in their quality. On satellite images from Cartosat-3, road markings are easily discernible, you can easily distinguish a truck from a passenger car and see parts of the aircraft in detail at the airport.

Description of the satellite Cartosat-3 satellite
The Cartosat-3 satellite was created for high precision mapping and ground observation to provide accurate geospatial data for civilian and military applications. It was launched on 27 November 2019 by the Indian Space Research Organization (ISRO).Cartosat-3 operates in a sun-synchronous orbit at an altitude of about 509 km, enabling it to obtain high spatial resolution images. The satellite is capable of receiving images with resolution up to 0.25 m in panchromatic mode and up to 1 m in multispectral mode.
The satellite operates in panchromatic and multispectral ranges, covering visible and near infrared spectrums. This allows Cartosat-3 to collect highly detailed data for the development of three-dimensional terrain models, environmental monitoring, urban infrastructure planning and other applications.
The development of the satellite is carried out by the Indian Space Research Organization (ISRO) and its associated Indian companies and research organizations working within the framework of the Indian Space Programme.
