Case Study: AWACS Network Upgrade using Modified COTS Helps Shorten Delivery

Version 1

    CS-tn-AWACS-Network-Upgrade-using-MCOTS.GIFFor the majority of operational airborne early warning and control aircraft (AEW&C) over 20 years old, on-board radar and networking systems are based on outdated technology that need to be upgraded to be effective in today’s airborne defense engagements. When one such aircraft fleet was undergoing an upgrade of the on-board AEW&C network, they contacted Curtiss-Wright to find a cost effective yet rugged, quick turnaround solution for multiple processing and communications subsystems.

     

    To withstand the harsh environmental conditions on-board the fixed wing aircraft, the equipment needed to meet DO-160 environmental, EMI, and power hold-up requirements. Electronics also had to be export controlled as commercial items and be available in time to meet the customer’s tight integration schedule. Additionally, they needed to ensure that the processor architectures used could handle single event upsets (from space radiation) by incorporating Error Correcting Code (ECC) memory and non-volatile removable Flash disks (to support sanitize procedures). Due to the sensitive nature of the data the system would handle, the integrator was interested in Intel-based solutions coupled with secure Cisco routing technology that had gone through FIPS 140 and Common Criteria evaluations, as provided by the Cisco 5915 Embedded Services Router.

     

    To keep program risk, costs and total system footprint down, the customer’s network architecture upgrade included four Small Form Factor (SFF) systems from Curtiss-Wright, ten in total on each aircraft, with redundancies included.
