Most waiting moment in science field to develop such spy satellite that is capable to imaging through clouds and even fog, will reach its targeted point in April as ISRO, the Indian Space Research Organisation will launch Radar Imaging Satellite (Risat-1).
Risat-1 is first completely an Indian-built a very high- resolution imaging surveillance satellite that seems to be more technical specification compared to other earlier built up remote sensing/earth observation satellites.
“The Risat-1 is put to thermal vacuum test (a test to check the satellite’s functioning in space environment). It is a complex microwave satellite being built for the first time in India. The satellite is expected to be launched in April,” the senior official of Indian Space Agency said.
Weighting 1,850 kg, Risat-1 will work in day and night even all weather, facilitating disaster prediction and agriculture forestry. It also sports microwave imaging that used for defence observation activity.
Upgrade variant of the Polar Satellite Launch Vehicle’s (PSLV), a four-stage rocket powered by solid and liquid propellants, called PSLV-XL will be used in the heaviest microwave satellite.
Even one main part of the Remote sensing satellite, the synthetic aperture radar (SAR) which can acquire data at C-band had installed in earlier satellite through importing. But this time it has developed in India itself.
With a huge success in space field, India has become the king of world providing imagery resolution satellite market and has 11 remote sensing/earth observation satellites orbiting in the space. These are TES, Resourcesat 1, Cartosat 1, 2, 2A and 2B, IMS 1, Risat-2, Oceansat 2, Resourcesat-2, Megha-Tropiques.
