With the gradual increase of the mission tasks and functional units of the integrated navigation system, but the development of technology requires the gradual improvement of system integration capabilities. The Integrated Navigation System face the main problem is the excess number of redundant units. Based on this situation, system need to simplify the the redundant configuration of functional units.
This paper analyzes the comprehensive efficiency based on the current k/n on-line spare element of the core equipment of the Integrated navigation system, proposed Markov model algorithm to build an assessment model of navigation system survivability, and comprehensively analyzed the impact of on-line spare element of the core equipment on the overall system efficiency. This paper establishes a simulation model of the reliability and availability of the navigation system, comprehensively consider the use conditions and economy, setting configuration guidelines based on engineering experience to design a reasonable redundant configuration of key core equipment.
This paper contributes to analyze the configurable number of key core equipment in the design of the Integrated navigation system, comprehensively considers the navigation system functional tasks and RMS factors such as reliability, maintainability, and supportability. from the perspective of system survivability by establishing a Survivability Model of Integrated Navigation Systems. This paper provides reasonable redundancy technology, and provides more reasonable design suggestions for system design with limited resources.
