Abstract: The apparent technical ability to develop a space-ground system which provides an advanced navigational aid to ships and aircraft has evolved during the past few years. One major factor in such a system is the data processing subsystem which is required to handle the large volume of position computations and messages. Such a system of satellites and computers is to provide fixes to its users both regularly and as requested. In contrast to existing systems these fixes are available to special agencies authorized to receive the information, and, as policy dictates, these agencies may use the system to exert positive control over the movement of ships and aircraft in the system. It provides complete transoceanic coverage; the usual static areas of poor technical performance are eliminated. We at UNIVAC have studied the data processing requirements for such a system. To identify the system onsidered we have formed the acronym AUTOSCAN, which is the abbreviation for Automatic Satellite-Computer Aid-to-Navigation. It is natural to ask whether the computers that are available now or in the next generation will have enough capacity and speed to handle the workload which is anticipated. This workload will be determined by the program which is required to run the computer, the amount of data which must be processed, and the speed at which the data must be processed.
