Abstract :
Describes the overall Landsat 7 System design, the design of selected system segments, and nominal operation of the system. The Landsat 7 System consists of four segments, satellite segment, flight operations segment, ground data handling segment, and launch segment. The discussion focuses on the design of the satellite segment which includes the spacecraft and instrument, and the ground data handling segment which includes the image processing and image assessment systems. Emphasis is given to design changes made to the spacecraft and instrument for the Landsat 7 mission to enhance performance and improve mission reliability. The ground data handling system discussion provides a high level overview of the Landsat processing system and image assessment system designs and their role in the overall system. This paper also describes the interfaces between the system elements and their interaction during nominal operations
