Abstract
This paper summarizes the system concept of the MLA Instrument as developed during the NASA Goddard Space Flight Center Instrument Definition Study (Contract No. NAS5- 26588). The purpose of this study was to encompass the definition, design and analysis of a candidate instrument to support an Experimental Land Observing System. In the process of this instrument definition, trade-off analyses have been conducted to identify and quantify technological risk, cost and performance with the intent of refining the MLA Instrument. The Multispectral Linear Array (MLA) instrument is a combined multi-channel radiometer and wide field imaging telescope for earth resources observation from space. The MLA sensor is designed to provide high resolution images as well as absolute radiometric measurement in 6 discrete spectral bands ranging from 0.45 to 2.35 μm. The Honeywell design centers around a reflective off-axis anastigmat that is well corrected for a 15° linear field-of-view. The major subassemblies are the telescope structure, focal plane/dewar assembly, radiative cooler, calibration sphere, stereo pointing mirror assembly, missed scene roll mechanism and the signal processing electronics module.
