Abstract

The preceding paper by Schnetzler and Thompson describes the Multispectral Resource Sampler, a visible and near visible sensor system for satellite borne assessment of earth resources which can be built using established technologies. In this paper, we will show how new technologies will make possible other design choices for future use in the 1985-1990 time frame. To make this example concrete, the characteristics of a suggested future earth resources sensor system are outlined in table 1. Inertialess pointing, i.e., the selection of a preferred ground area beneath the track, is provided without need for mechanical motion, figure 1, by selecting a short segment of a long detector array. The system provides a 10m x 10m detector footprint with 18,500 detectors in the visible array to cover a 185Km swath width across the vehicle track. The near and far infrared arrays use proportionally fewer larger detectors to maintain for all three spectral regions the same ratio between detector dimensions and the diffraction limit of the 30 cm aperture f:3.5 optical system.
