ISRO and Jet Propulsion Laboratory (JPL)/NASA are jointly working on the development of Dual Frequency (L&S band) Synthetic Aperture Radar Imaging Satellite named as NASA-ISRO Synthetic Aperture Radar (NISAR).
In this joint mission, JPL/ NASA will be responsible for design & development of L-band SAR, 12m unfurlable antenna & its deployment elements, GPS system and data recorder. ISRO will be responsible for design & development of S-band SAR, Spacecraft Bus, data transmission system, Spacecraft integration & testing, launch using GSLV and on-orbit operations.
The L & S band microwave data obtained from this satellite will be useful for variety of applications, which include natural resources mapping & monitoring; estimating agricultural biomass over full duration of crop cycle; assessing soil moisture; monitoring of floods and oil slicks; coastal erosion, coastline changes and variation of winds in coastal waters; assessment of mangroves; surface deformation studies etc.
ISRO and JPL/ NASA are working towards realisation of this mission by 2021. Both agencies have obtained necessary approvals from respective governments.
The joint science observation plan has been documented with the participation of Indian and American scientists. The core science teams of India and USA meet every six months to discuss various observation requirements and strategies of science observation. The technical teams of both the agencies are working towards building the necessary systems.
