Introduction

摘要

Dr. Babu described NASA ESTO, its recent emphasis on small and cube satellites for accomplishing the Earth observing missions, and some of the potential game changers. Higher levels of risk now accepted, especially for new emphasis on smaller payloads. The emphasis on smaller payloads (Weather radar example) and a spectral radiometer made possible with an innovative NiP bolometer highlighted the emphasis on TRL progression. The progression of dispersive spectrometers is another good example, with package dimensions now measured in mm for smaller aperture, lower spectral resolution applications. These truly tiny dispersive spectrometers showcase the thrust to minimize sensor hardware SWAP. Novel sensor array technologies are underway, perhaps impacting the commercial market as well. How to measure infusion of the developed technologies? The rate of increase of their technology readiness levels. One of the noted principal investigator concerns has been maintaining an emphasis on well-calibrated data, which traditional NASA earth imagers achieved with sophisticated, on-board calibration equipment. These needs are now being met with a larger network of calibrated Earth scenes.
