System engineering studies for advanced geosynchronousremote sensors: some initial thoughts on the 4th generation

摘要

Future operational geosynchronous remote sensors will respond to a broad range of environmental andmilitary/intelligence mission needs. This paper describes initial system engineering design studies for 4thgeneration operational geosynchronous remote sensors that address notional future mission requirements.Two hyperspectral sensor architectures were considered: an imaging Fourier transform spectrometer and animaging prism spectrometer. While both imaging FTS and dispersive approaches are viable over a broadtrade space, each requires new technology that must be demonstrated low risk by 2017 to enable a missionpathfinder by 2025. To reach this important objective requires that technology risk reduction start now.
