Astro Aerospace, a Northrop Grumman Corporation (NYSE:NOC) company, has completed the preliminary design review (PDR) of the AstroMesh radar antenna reflector for the NASA-ISRO synthetic aperture radar (NISAR) satellite, the company said.
The antenna reflector, furnished by Astro Aerospace, is part of the NISAR L-band synthetic aperture radar managed by NASA´s Jet Propulsion Laboratory. NISAR´s radar imaging satellite uses dual L-Band and S-Band frequencies, providing a detailed view of Earth.
NISAR is designed to observe some of the planet´s most complex processes, including ecosystem disturbances, ice-sheet dynamics, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides. Data collected from NISAR will reveal information about the evolution and state of Earth´s crust, help scientists better understand the planet´s processes and changing climate, and aid future resource and hazard management. The mission is a partnership between NASA and the Indian Space Research Organization (ISRO).
