Abstract
MIL-STD-1553B communication is globally used in the area of aerospace and defense which require safety and reliability in spite of its low communication speed. As recently increased requirements for high precision and robust guidance ability of missiles, missile sensor equipment needs more data to satisfy those requirements. Therefore, missile systems to adopt MIL-STD-1553B requires higher data transfer and processing capability than those of the current systems. In this paper, we describe the result of analysis and implementation of the existing methods that applied multi-message chain and double buffers to improve the current missile system.
