Abstract
The PRISM instrument is an imaging radiometer to be flown on a satellite in Earth orbit. The principle mission is to gather Earth radiance data from land areas, at a spatial resolution of approximately 50 m. It will have spectral resolution in the order of 10 nm in the visible to short- wave IR spectral band, and a few discrete spectral bands in the thermal IR. It will typically be operated to record multi-spectral images of selected areas about 50 km square. The field of view of the instrument must be capable of pointing control, in both across-track and along-track directions, to select specific targets in each orbit and to view selected targets in different directions. The instrument is in an early stage of concept development, in competitive studies carried out for the European Space Agency. The paper describes the principle conclusions of the initial study of the team led by Dornier Satellite Systems, with Sira and Matra Marconi Space as principle sub- contractors. Outline designs are presented for: pointing optics, imaging and relay optics, imaging spectrometer, channel separation and in-flight characterization. Brief notes are given on design trade-offs and rationales for baseline selections.
