Advanced Satellite Hardware/Software System Study.
Abstract
This report provides an overview of the Landsat-D program and the anticipated requirements of the Corps of Engineers for the application of Landsat data to operational programs. A general discussion of the candidate data analysis requirements, including data input and output and other data preparation processes provides a complete description of the capabilities which will be required of an advanced satellite hardware/software image analysis system. A brief overview of the currently available hardware technology provides a basis for the synthesis of the hardware system design, and an example of a typical software structure, based on that for an actual system, is presented. Descriptions of three candidate system architectures provide examples of different approaches to the development of a system meeting the Corps of Engineers requirements, and the problems of communication between remoted terminals and a host processor are addressed, together with the problems related to the dissemination of data to remotely located independent systems. A brief cost analysis indicates the system cost drivers, and shows how cost tradeoffs may be made in developing a specific system. A candidate system design for the Corps of Engineers is presented, based on the concept of independent systems with capabilities tailored to local requirements. (Author)
