Abstract:Virtual test and evaluation technology can effective support the test validation of complex aerospace products. A research and implementation of VITA(virtual test and evaluation enabling Architecture) is carried out, to meet the technology needs of the development of aerospace products. The VITA system is composed of runtime middleware and a series of auxiliary tools to support the full life cycle of the“test design-test run-test analysis”of the virtual test application system. This paper introduces the implementation of VITA, include runtime middleware, integrated development environment, test design, dispatching management, test data record and playback, test result analysis, test data management, software gateway, hardware gateway and so on. VITA is used in the process of product’s development, application shows that VITA supports the verification of the technical performance for product’s key systems, and effectively solves the product’s large-scale joint test problem.
