Space shuttle vehicle automatic docking study

The material presented is divided into three main areas of accomplishment. The first is a description of the angle only docking sensor concept and the computational requirements to develop useful guidance information from the raw angle only data. The second describes the analytical effort including the MIT in-house computer simulation, the development of guidance equations and vehicle stability related thereto, and presents the results of studies covering the effects of employing Kalman filtering with the sensor. The third area presents the conclusions and recommendations resulting from the program. Much of the material has appeared in previous reports, but is included here for the sake of completeness. New material indicating how the computer might operate to identify the individual sources in the target array is included.
