In response to the problem of inaccurate results caused by subjective factors in the evaluation of navigation equipment in the past, this paper proposes an evaluation method that combines Analytic Hierarchy Process (AHP) with Quality Function Deployment (QFD), with task requirement satisfaction degree as the evaluation indicator of navigation equipment capability.This method combines qualitative and quantitative analysis, based on the mapping process of navigation equipment of support task to capability requirements to tactical/technical indicators, proposes the evaluation steps of determining mapping domain indicators, calculating the importance of combat support capability, determining relationship matrix, and calculating the satisfaction degree of task requirements, and provides the method for calculating the satisfaction degree of requirements. Finally, an example of land-based Beidou navigation equipment support is analyzed, and the results prove the feasibility of this method, which is of great significance for the performance optimization and practical use of navigation equipment.
