Eyes in the sky

Indian Space Research Organisation (ISRO) is all set to launch a new earth observatory named CartoSat-2C in May. The satellite built for military purposes will blast off using the renowned PSLV (Polar Satellite Launch Vehicle). After the launch, India will join the ranks of China and USA who have their own spy satellites to monitor activities on Earth from space.
Indian space scientists built the satellite at the Space Applications Centre  (SAC) in Ahmedabad. Several rounds of tests were performed to check the durability and functioning of the satellite. Two weeks ago, CartoSat-2C was shifted to ISRO Satellite Centre (ISAC) at Bengaluru. India’s first dedicated military satellite — CartoSat-2A was launched in 2007 and since then it has given very sensitive and highly classified information including the missile launches in the neighbourhood.
According to the official report, the satellite weighs 690 kilogram. The high-resolution multi-spectral instrument and Panchromatic Camera will enable the satellite to capture some stunning high-resolution images. Previous military satellite had the resolution of 0.8 metre while the new camera installed on the CartoSat-2C has a resolution of 0.65 which means that it can spot even smaller objects from space. What’s striking about the camera of the new satellite is that it has the capability to record videos, process it to reduce size of the file and then beam it back to the Earth.
CartoSat-2C will blast off along with 21 other satellites using PSLV rocket in May this year. It will be placed in a sun-synchronous polar orbit at a low-earth altitude of about 200-1,200 kms above the Earth’s surface. Once launched, it will be one of the finest eyes present in space.
ISRO officials describe this satellite “as one of the best eyes in space” that India has launched till date. The strength of the camera installed in this home-grown satellite is almost at par with the ones possessed by US and China. For instance, in 2014, the Chinese had set a remote sensing satellite “Yaogan 24” which had a similar camera of 0.65 metre resolution. The panchromatic imagers can not only be used for surveillance, but can also aid in disaster monitoring. It will also click images that can give an idea of temperatures of a particular location in comparison with the surrounding areas. Cartosat-2C is expected to be launched along with 21 other satellites in May using a PSLV rocket. It will be placed in a sun-synchronous polar orbit at a low-earth altitude of about 200-1,200 kms above the Earth’s surface. - See more at: http://indianexpress.com/article/cities/ahmedabad/cartosat-2c-to-boost-military-surveillance-capabilities/#sthash.IugXyw6r.dpuf
