Avionics systems require an increased range of processing elements, networks and peripheral devices with increased reliability and decreased costs. Inflexible hardware-based fault-tolerance is a significant life cycle cost. Reliable Platform Service (RPS) software provides superior fault resilience while utilizing commercial off-the-shelf (COTS) components. Significant cost savings in hardware and faster lifecycle upgrading are achieved, keeping pace with commercial developments, all of which require extremely robust fault awareness and tolerance. RPS also permits dynamic fault tolerance over changing configurations and operating modes and is scalable/extensible to legacy or new systems. RPS fits into the Modular Open Systems Architecture (MOSA) and Future Airborne Computing Environment (FACE) of avionics components. Our goal is to transition this technology into government and prime contractor systems to provide robust, affordable fault protection.
WW Technology Group develops model-based architectural analysis software tools for high dependability and safety critical systems certification. More than 20 years of experience in designing and fielding critical systems gives WWTG a unique and powerful perspective on the challenges associated with deploying and certifying complex safety critical networked systems. Our tools enable the analysis of system safety and reliability properties using model-driven engineering approaches and support certification by collecting the evidence required through open and flexible means. These capabilities result in significant development and life cycle cost savings for certification efforts along with improved certification accuracy and decreased program risk. WWTG seeks customers who require tools to address their system design and/or certification cost needs and wish to establish a strategic advantage though these tools.
