The Satellite Data Model (SDM) is part of the Air Force Research Laboratory (AFRL) Responsive Space Testbed Initiative. It is a developing standard for rapid integration of hardware and software components in a satellite network. The SDM is a middleware software system providing self-configuration and self-discovery capabilities in multiprocessor networks of applications, sensors, and actuators. By allowing both software and hardware to selfdiscover and self-configure, the SDM supports rapid development and integration of satellite networks. The SDM is intended to provide a completely generalized device-application interface whereby applications can be written independently of their data sources and messaging and without knowledge of the final data consumers. Similarly, sensors and actuators can be built without concern for specific applications or what processes they will interact with. 1 The Responsive Satellite The primary goal of the Responsive Space Testbed Initiative of the AFRL...
