Abstract

This paper summarizes post-critical design review (CDR) design refinements and performance estimate updates to the National Polar-orbiting Operational Environmental Satellite Systems (NPOESS) Visible Infrared Imager Radiometer Suite (VIIRS) sensor. The design changes reduced manufacturing and performance risk to meet VIIRS sensor performance specifications. Electro-Magnetic Compatibility (EMC) and Electro-Magnetic Interference (EMI) requirements drove increased shielding and cable modifications. A telescope design modification was also required to remove modulated instrument background (MIB) discovered in the CDR optical design. Performance predictions were then generated from models and demonstration hardware based on the design refinements, and these are also reported here. VIIRS risk-reduction will continue as the Engineering Development Unit (EDU) is assembled and tested over the next year facilitating performance verification and lowering flight unit development risk.
