CARTOSAT-2

Cartosat-2 was an Earth observation satellite in a Sun-synchronous orbit and the second of the Cartosat series of satellites. The satellite was built, launched and maintained by the Indian Space Research Organisation (ISRO). Weighing around 680 kg at launch, its applications were mainly be towards cartography . It was launched by the Polar Satellite Launch Vehicle PSLV C7 launch vehicle on 10 January 2007.

== Satellite description == Cartosat-2 carried a state-of-the-art panchromatic (PAN) camera that took black and white pictures of the Earth in the visible region of the electromagnetic spectrum. The swath covered by this high resolution PAN camera was 9.6 km and their spatial resolution is less than 1 metre. The satellite could be steered up to 45° along as well as across the track. Cartosat-2 was an advanced remote sensing satellite capable of providing scene-specific spot imagery. The data from the satellite was used for detailed mapping and other cartographic applications at cadastral level, urban and rural infrastructure development and management, as well as applications in Land information system (LIS) and Geographic information system (GIS). The first imagery, received on 12 January 2007, covered a length of 240 km from Paonta Sahib in Shivalik region to Delhi. Another set of imagery of about 50 km length covered Radhanagari to Sagoan in Goa. Analysis of the first imagery received at National Remote Sensing Agency's data reception station at Shadnagar, in Hyderabad, confirmed excellent performance of the on-board camera.
