New Delhi. The Indian Space Research Organization (ISRO) was launched on NASA-Israo Synthetic Aperture Radar (NISAR) mission on Wednesday. The Satish Dhawan Space Center at Sriharikota, Andhra Pradesh was launched at 5:40 pm on Wednesday at 5:40 pm through GSLV-S16 rocket. This is the first mission in which for the first time such a satellite will be installed in Sun-Synchronous Orbit (Sun-Term Room) through a GSLV rocket.
The GSLV rocket will install the satellite in a synchronous polar orbit at a height of 745 km after a visit of about 19 minutes. The Sun is the orbit of synchronous polar orbit, in which the satellite passes over the Earth’s poles and every time it passes through a particular place, the sunlight is the same. Kavuluru told about the mission that NASA has provided L-band for Nisar while ISRO has provided S-band for synthetic aperture radar. This will make it possible to collect large amounts of data. This satellite will broadcast extensive data to Earth, including Antarctica, North Pole and Oceans.
Data will be collected from the world, the government of every country will use
Kavuluru said that Nisar will collect data from all over the world and it will be used for commercial and scientific objectives. Kavuluru said, “ISRO will process this data and provide a majority of it as open-sources, so that users around the world can get it easily.” With this, we will be able to monitor seasonal changes including changes in forests in areas like Himalayas and Antarctica, changes in mountains or locations and activities of glaciers.
Data of the entire Earth in 12 days
According to ISRO, NASA-Israo synthetic aperture radar (Nisar) satellite launch will prove to be an important milestone in long cooperation between the two space agencies. ISRO reported that this satellite will scan the entire earth every 12 days, and day and night, will provide high-regulatory data in every season. The satellite will be able to identify extremely subtle changes on the surface of the Earth, such as a change in vegetation, sliding of snow sheets and deformity of the ground.
ISRO said that this mission will help in many important areas such as monitoring of sea level, detection of ships, changing soil moisture, mapping of surface water resources and disaster management. This satellite will detect light cracks in the ground or a change in ice sheet from the earthquake.
This satellite works on two bands
The GSLV-F18 will install this satellite in a 743 km high sun-cycronus orbit. The inclination of which will be 98.40 degrees. Nisar is the first satellite in the world to monitor the earth. It has two different bands (NASA’s L-bands and ISRO S-bands) radars. Due to which he will be able to collect data from under the dense forests. ISRO chief said that this is a very important satellite. It has two major payloads: an S-band payload. Which ISRO has fully developed in its Ahmedabad lab and the second- JPL-developed L-Band payload. Both payloads have been combined and integrated into a satellite.
Synthetic aperture radar
Nisar Satellite SAR has been used. With this technique, very good pictures can be taken with the help of radar system. With the help of this technique, high-rugulation photos of the entire Earth’s surface will be taken every 12 days. Both radars will receive data through NASA’s 12 -meter spreading mesh reflector antenna. Which is added to ISRO’s i3K bus. This satellite will inspect the Earth with a width of 242 km and high spatial resolution. Both of them will monitor the decreasing number of trees and plants on the earth, as well as study the effect of lack of light and more.
