Rugged COTS Systems

NAI’s family of highly configurable Rugged COTS Systems are ideally suited for defense, commercial aerospace, and industrial applications that require high-density I/O, communications, Ethernet switching, and processing for mission-critical tasks such as communications, guidance, sense and response, data acquisition and motion control. The simplified, modular approach of our Configurable Open Systems Architecture™ (COSA®) enables us to use the same building blocks across multiple platforms and programs, making it possible for you to develop semi-custom solutions quickly, without NRE, while retaining all the benefits of COTS products.
