CrIS Flight Model 1 delivered performance

This paper summarizes the results of final performance tests of the first Cross-track Infrared Sounder (CrIS) instrument, which is a critical payload for the NPOESS Preparatory Project (NPP) mission. This unit has recently been delivered and integrated with the NPP spacecraft, and is now undergoing spacecraft-level tests prior to launch in 2011. The paper includes a description of the instrument-level test program and key test results from Thermal Vacuum, EMI, and Vibration testing. Radiometric, spectral, and spatial performance is described.
