Development of Compact Optical Instrumentation for Studying the Earth Upper Atmosphere Emissions on the Board of International Space Station

摘要

In presented work the technical pattern of Spectral Photometrical Complex (SPC) is described and the results of calculations of required energetic, spectral and temporal parameters of SPC are given. The plan of experiment "Hydroxyl" at International Space Station (ISS) with SPC instrumentation supposes carrying out the sessions of observations of Earth upper atmosphere at the night-side of the Earth. The absolute hydroxyl emission intensities will be measured with spectral resolution better then 0.5 nm in region of 830 - 1040 nm together with atomic oxygen green line emission at 577.7 nm. The measurements will be carried out in Earth limb direction. The spatial resolution of emission images is supposed to be better then 1 km.
