Lynx Software Technologies announced that General Atomics Aeronautical Systems, Inc. (GA-ASI) has adopted the LYNX MOSA.ic software framework for the Gray Eagle Extended Range (GE-ER) Unmanned Aircraft System (UAS).
The company says LYNX MOSA.ic is aligned with GA-ASI’s objectives to meet software-modernization targets for the GE-ER program that include safety and cost efficiency, as well as introducing new features, increasing system robustness and securing future flexibility.
The GE-ER is a multi-mission UAS including surveillance and other intelligence gathering. The air vehicle carries sensors including color and thermographic cameras, and is piloted remotely from a ground-control station via satellite data link or optionally by line-of-sight data link. An early goal of the software modernization 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 allowed the incorporation of the Xilinx hardware without compromising hardware dependencies or the performance and determinism of other time-critical processes.
Although DO-178 certification isn’t 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 an advantage.
