U.S. Army to deploy BAE Systems DGNS supported by AMD GPU, CoreAVI graphics, Green Hills RTOS, DO-178C certification package.



TAMPA, Fla. Core Avionics & Industrial Inc. (CoreAVI) in Tampa, Florida, has integrated its ArgusCore SC (OpenGL SC) graphics driver with BAE Systems’ ASN-128E Doppler/Global Positioning System Navigation Set (DGNS). The OpenGL SC driver delivery supports the AMD Embedded Radeon graphics processing units (GPUs) and includes a Card Support Library provided by BAE Systems running on Green Hills Software’s INTEGRITY-178 real-time operating system (RTOS).

The completed driver delivery included CoreAVI’s CertCore178 data package, a complete RTCA DO-178C graphics driver certification package. The OpenGL SC graphics driver is part of CoreAVI’s suite of safety-certifiable drivers developed to RTCA DO-178C/EUROCAE ED-12C certification standards; the suite includes: DecodeCore (H.264 video stream decode driver), EncodeCore (H.264 video encode driver), and HyperCore, a safety-critical GPU virtualization manager for hypervisor platforms. These drivers have certification packages supporting up to and including Design Assurance Level (DAL) A, the most stringent level.

BAE Systems’ ASN-128E is a self-contained Doppler navigation set that provides autonomous point-point navigation. This represents the fourth upgrade of the ASN-128, adding military Global Positioning System (GPS), Instrument Flight Rules (IFR) certification, and removing obsolescence.

The graphics update to the Computer Display Unit (CDU) portion of the ASN-128D provides an improved display capability for critical data with integrated information to decrease pilot workload. The CDU features a touchscreen display with an intuitive pilot interface for moving maps with vertical obstruction overlay, and electronic Flight Information Publication (FLIP) charts, as well as many more capabilities.

The U.S. Army is modernizing the existing DGNS CDU for deployment on UH-60L helicopters.

CoreAVI also continues to provide long-term managed supply of extended temperature range AMD Embedded Radeon GPU devices.

“CoreAVI has successfully merged our Card Support Library software with the graphics driver to provide an integrated safety-critical driver library for our set,” says BAE Systems Doppler Program Manager Bill Friedman. “CoreAVI provided an open and supportive environment leading to this successful OpenGL SC driver delivery on our target hardware and operating system platform.”
