Mercury Systems has developed what it says is the industry’s first safety certifiable mission computer aligned with the SOSA open sensor systems architecture.

The Avionics Modular Mission Platform (AMMP) is a 3U Open VPX system that is certifiable to the five DAL (design assurance levels) that are specified by the DO-254 and EUROCAE ED-80 safety standards. Although SOSA is a US consortium to promote building systems from interoperable, commercial off the shelf (COTS) boards and software, it is also being adopted in Europe.

The Mercury AMMP uses multiple Intel Core i7 Gen 11 safety-certifiable processors with integrated GPUs to provide up to 40x more performance than current-generation avionics computers while drawing 50% less power. It is aimed at a wide range of platforms including rotary- and fixed-wing aircraft, ground stations and unmanned aerial vehicles.

The system is specifically designed to support real-time safety-critical applications such as mission management, sensor fusion/processing, surveillance, 5G communications and artificial intelligence (AI). The computer comes integrated with Mercury’s BuiltSAFE COTS multi-core single board computers, avionics IO, video processing and software to simplify integration and the certification process.

“Safety-certified flight mission computers are often built with custom or proprietary architectures that make them difficult and expensive to maintain and upgrade,” said Jay Abendroth, vice president, Mercury Mission. “In contrast, our AMMP system offers the combination of commercial processing, DAL-A artefacts and alignment with the SOSA specification. This is a great example of how our strategy and investments in secure processing, trusted microelectronics, and open mission systems are serving as the engines of growth in the business. It also aligns well with the DoD’s need for open mission systems supporting their modular open systems approach (MOSA) mandate.”

There is a range of avionics I/O including ARINC-429 to capture and distribute HD video and fully configurable, independent 3U boards to run multiple, mixed safety workloads. Software from Green Hills and Lynx and Linux board support packages support the FAA’s CAST-32A certification.

Mercury can also integrate a display, mapping system, cockpit management system and sensors with AMMP to maximize interoperability, optimize display performance and save customer integration time.
