Mapsat conceptual design; system overview

After more than 10 years of study and applications of Earth imaging satellite systems, the U. S. Geological Survey has conceptually defined a candidate Operational Land Remote Sensing Satellite. A conceptual design study of this system, known as MAPSAT, has been completed by Itek Optical Systems, a division of Itek Corporation, and the TRW Defense Systems and Space Group. The concept of MAPSAT is based on LANDSAT mission, sensing, and data communication characteristics, but reflects the evolution of technological and application responsiveness.
