Astro Aerospace completes CDR of radar antenna for NISAR satellite

CARPINTERIA, Calif. Engineers at Astro Aerospace, a Northrop Grumman Corp. business, completed the Critical Design Review (CDR) of the AstroMesh radar antenna reflector for the NASA-Indian Space Research Organization (ISRO) Synthetic Aperture Radar (NISAR) satellite.

Post CDR, the program will move into the “build” phase of the AstroMesh radar reflector in preparation for the scheduled 2021 launch date. will use its proprietary AstroMesh deployable mesh reflector for NISAR’s large aperture antenna, building an ultralight and extremely stiff reflector that is suited for high frequency communications and radar applications.

NISAR will make global integrated measurements, providing a detailed view of Earth. NISAR’s radar imaging satellite will use dual L-Band and S-Band frequencies to measure the causes and consequences of land surface changes. The data collected will provide information to better manage resources and global change. NISAR is a partnership between NASA and the ISRO. NASA’s contribution to NISAR is being managed and implemented by the agency’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
