The In this paper, the ground integration test and verification platform for airborne radio communication navigation surveillance (CNS) equipment is studied and designed to meet the demand for ground integration test and verification of airborne CNS equipment before installation, and the technical scheme of the platform is formulated and its main functions are introduced. The platform uses real and partly simulated airborne CNS equipment, combining with excitation control platform and comprehensive excitation equipment, can complete the closed-loop testing and analysis of airborne radio CNS equipment without the help of other avionics systems, and provide real airborne system information output for flight management system and other avionics systems, and realize remote management of the whole system by using various remote control means. It has good versatility, scalability, easy maintenance, and other characteristics, and by combining with the 3D flight vision system to give users an intuitive, vivid visual display at the same time. The test shows that the platform can achieve the design goals of stimulation, testing, data analysis and fault location for airborne radio CNS equipment, reaching the domestic advanced level, which is of great significance for the development of airborne CNS equipment testing and application technologies.
