Abstract
The system consists of a satellite position and attitude reference system utilizing Global Positioning System data, an on board computer to analyze and generate position and attitude dependent instructions, an attitude control system to adjust the attitude of the space craft in response to instructions from the computer, an imaging system responsive to the computer to generate image data and transmit it, and a ground based, image data receiver and post processing system to assemble the image data, code the data and compile sequential images into a mosaic depicting the target. The on board computer delays the generation of attitude control instructions, during the process of capturing image data, in order to avoid image distortion due to attitude adjustment movement of the spacecraft.
