Rugged COTS Systems


Rugged COTS Switches

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.

Rugged Ethernet Switches

Today’s smart, sensor-based combat systems must acquire, process and share large amounts of real-time data from diverse sources continuously – and with a high level of readiness. NAI’s Rugged Systems are designed to provide fast, fail-safe access to sensor-based information in the harshest military environments while optimizing size, weight and power requirements.

NAI offers, and continues to support, primary or single-function I/O boards designed for a specific, single-purpose application. Based on the specialized application itself, from the interface connectors through the motherboard, to the specific function, these boards typically address I/O function integration challenges requiring higher current capacity, layout, and/or grounding requirements. They are specifically designed for rugged defense, commercial aerospace, and industrial applications.
