Orbit Environment Analysis of the Space-borne Imaging Spectrometer

摘要

This paper summarizes the technical specifications of the Space-borne Imaging Spectrometer. The remote sensor consists of 20 bands including visible, near infrared, short wave infrared and thermal infrared channels. The engineering model (EM) was completed. Using the software CODEV, we discuss the influence of the space-borne environment, different temperature, especially different assembling material on this instrument. Data show that the main optical system is sensitive to the space-borne temperature; the space image quality is affected heavily by the assembling material and etc. The orbit environment analysis is of great advantage to the optical set-up, environment experimentations and cost saving.
