A flexible data handling concept

Abstract

A data-handling and control concept which uses a data bus to integrate digital data in satellites is presented. Onboard sensor data are processed to generate messages that utilize a data bus to provide flexible interconnections with other onboard processors and, through a communications network, to other satellites and the ground. A design that can be tailored to meet the requirements of different satellites is addressed. Design options are analyzed and summarized. Standard bus interface units are available to adapt different processors permitting easy integration into the satellite system. A MIL-STD-1750A processor that meets US DOD requirements supported by software tools permitting the use of Ada has been developed.<>
