INSUBCONTINENT EXCLUSIVE:
Nellore: S-Band Synthetic Aperture Radar (SAR) payload developed at the Space Applications Centre (SAC), Ahmedabad, of the Indian Space
Research Study Organisation has actually been shipped to the Jet Propulsion Laboratory (JPL), Pasadena, California
It will be incorporated with the L-Band SAR Payload of JPL for the Nasa-Isro Synthetic Aperture Radar (Nisar) mission which is arranged to
The objective will have a minimum lifetime of three years
The payload was flagged off by Isro Chairman Dr K
Sivan recently in the virtual mode
Isro stated the Nisar satellite will provide a comprehensive view of the Earth to observe and determine some of the planet's most complex
processes, consisting of environment disruptions, ice-sheet collapse, and natural risks
Similar to Nasa objectives, the Nisar data will be openly offered, free of charge.The objective will likewise can supporting catastrophe
reaction through expedited event-driven downlinking, processing, and delivery of appropriate data.Nisar will use 2 artificial aperture
radars (SAR) operating at different frequencies to study the Earth
Nasa will provide the L-band SAR and Isro the S-band SAR
The L-band devices will offer all-weather, day and night imaging of nearly the entire land and ice masses of the Earth and the S-band
instrument will provide extra protection of India and parts of the polar regions.Most areas will be imaged four to 6 times a month, with
exact repeat of the orbits at 12-day intervals
Nisar's imaging resolution will be 3-50 metres, relying on the operating mode.The repeat orbit images can be utilized to identify and track
the subtle motion of the Earth's land using interferometric artificial aperture radar (InSAR) that can discover small-scale surface
contortion prior to it shows up to the eye
Nisar will be the first radar of its kind in space to systematically map the Earth utilizing 2 different frequencies (L-band and S-band) to
measure modifications in the world's surface area of less than a centimeter across.Click on Deccan Chronicle Technology and Science for the
