Abstract
The Night Vision Imaging Spectrometer (NVIS) system has participated in a large variety of hyperspectral data collections for the Department of Defense. A large number of improvements to this system have been undertaken. They include the implementation of a calibration process that utilizes in-flight calibration units (IFCU). Other improvements include the completion and implementation of an updated laboratory wavelength assignments map which provide precise bandwidth profiles of every NVIS pixel. NVESD has recently incorporated a Boeing C-MIGITS II INS/DGPS system, which allows geo-rectification of every frame of NVIS data. A PC-based Dual Real Time Recorder DRTR was developed to extend the collection capability of the sensor and allow the concurrent collection of data from other devices. The DRTR collects data from the NVIS, a Dalsa imager, and data from the CMIGITS-II (C/A code Miniature Integrated GPS/INS Tactical System) which provides navigation information. The integration of the CIMGITS-II allows every data frame of both the NVIS and the DALSA to be stamped with INS/GPS information. The DRTR software can also provide real-time waterfall displays of the data being collected. This paper will review the recent improvements to the NVIS system.
