Advanced earth observation satellite Cartosat-3, which is due to be launched from the Satish Dhawan Space Centre SHAR at Sriharikota in coastal Andhra Pradesh on Wednesday morning, will have the “sharpest eye” of civil remote sensing satellites in the world. It will be carried by PSLV-C47. Thirteen small satellites of two U.S. customers will be the secondary payloads.
A 26-hour countdown began for the launch began on Tuesday morning.
A key feature of the Cartosats is that they help to detect changes in natural geographical or man-made features. Their cameras can `look back and forth’ in an angle to generate continuous spot images.
Cartosat-3 is unusually heavy and contains new technologies such as a highly agile or flexible camera; high-speed data transmission, advanced computer system and new power electronics, according to website Space Skyrocket.
One of Cartosat-3’s cameras offers a ground resolution of 25 cm – this means it can pick up an object of a minimum of that size from a height of around 500 km.
So far, the Indian Space Research Organisation (ISRO) has orbited eight Cartosats since May 2005.
The second one, Cartosat-2 of January 2007, breached the 1-metre threshold, which was an ambitious benchmark at that time.
The previous best view from a Cartosat was 65 cm, as put in the last three or four satellites in the Cartosat-2 series – 2C, 2D, 2E and 2F.
According to the ISRO, “The imageries from [Cartosat series] satellites are useful for cartographic applications, urban and rural applications, infrastructure planning, coastal land use and regulation, utility management such as monitoring road networks, water grids or distribution, creation of land use maps, among others.”
