Astro Aerospace completes NISAR CDR
Astro Aerospace has completed the critical design review of the AstroMesh radar antenna reflector for the NASA-Indian Space Research Organisation (ISRO) synthetic aperture radar (NISAR) satellite, Northrop Grumman announced on 29 January.
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.
The programme will now move into the build phase of the AstroMesh radar antenna reflector in preparation for the scheduled 2021 launch date.
Northrop Grumman will use its proprietary AstroMesh deployable mesh reflector for NISAR’s large aperture antenna, building an ultralight and stiff reflector that is ideally suited for radar applications and high frequency communications.
