ABSTRACT
MIL- STD -1553 is a standard that defines the electrical and protocol characteristics for a data bus. AS-15531 is the Society of Automotive Engineers commercial equivalent to the military standard. A data bus is similar to what the personal computer and office automation industry have dubbed a “local area network.” MIL-STD-1553 has been deployed on fixed- and rotary-wing aircraft, unmanned aircraft, surface and subsurface ships, ground vehicles, spacecraft and satellites, and the International Space Station. It is undoubtedly one of the most successful military standards developed. MIL-STD-1553B defines the term time division multiplexing as “the transmission of information from several signal sources through one communications system with different signal samples staggered in time to form a composite pulse train.” As MIL-STD-1553 has expanded into more and more avionic architectures, system architecture questions have been raised concerning the location and design assurance level of the bus Controller.
