Safe, Cost-Efficient, Robust and Flexible Software Upgrades
Lynx Software Technologies announced on 26 August that its LYNX MOSA.ic software framework has been adopted by General Atomics Aeronautical Systems (GA-ASI) for the GRAY EAGLE Extended Range (GE-ER) UAS.
LYNX MOSA.ic is aligned with GA-ASI’s objectives to meet software modernisation targets for the GE-ER programme that include safety and cost efficiency as well as introducing new features, increasing system sturdiness and securing future flexibility.
GE-ER is a multi-mission UAS, whose sensors include colour and thermographic cameras and which can be controlled remotely from a ground control station via satellite datalink or optionally by line-of-sight datalink. An early goal of the software modernisation sought to integrate a new and advanced video codec implemented on the Zynq UltraScale+ adaptable multiprocessor system on chip (MPSoC) from Xilinx, Inc. The modularity of LYNX MOSA.ic enabled the team to achieve an efficient and robust solution in a mixed criticality environment, including both Linux and a deterministic real-time operating system. LYNX MOSA.ic securely partitions networking, security, safety and multimedia domains from each other, with prescriptive, defined and immutable allocation of hardware resources to each. This allows for incorporation of the Xilinx hardware without compromising hardware dependencies or the performance and determinism of other time-critical processes.
Although DO-178 certification is not an immediate requirement for the system, GA-ASI views the fact that Lynx provides a proven DO-178-certified OS with a path to DAL-A support as a significant advantage.
“The video codec on the Zynq UltraScale+ supports concurrent 4K 60fps video encoding, decoding and transcoding, is extremely efficient and will extend the capabilities of GE-ER, leveraging features of LYNX MOSA.ic to ensure reliability and system safety,” stated John Blevins, Senior Manager, Embedded Software and Ecosystem, at Xilinx.
“GA-ASI is a recognized innovator and leader in its field of unmanned aircraft [and] our focus now is on ensuring the successful execution of this program through the development and into deployment,” added Pavan Singh, VP Product Management.
GA-ASI identified LYNX MOSA.ic as the best platform to satisfy current and future demands for GE-ER modernisation. Supporting today’s computing trends moving towards multicore processors and hardware acceleration leveraging complex programmable SoCs, LYNX MOSA.ic enables real-time and commercial operating systems, as well as bare-metal software, to coexist on the same platform and maintain robust separation. The platform’s open integration framework promotes safe software re-use to help realise cost efficiencies and shorten development and integration cycles. With unique features to optimise hardware on boot-up and securely lock down the configuration to prevent unintentional modification or malicious interference, LYNX MOSA.ic ensures operational safety and sturdiness and provides state-of-the-art cybersecurity.
