Operating system evolution and history

LynxOS is the company's real-time operating system. It is UNIX-compatible and POSIX-compliant. It features predictable worst-case response time, preemptive scheduling, real-time priorities, ROMable kernel, and memory locking. LynxOS 7.0 is marketed as a "military grade", general purpose multi-core hard real-time operating system, and is intended for developers to embed security features during the design process, rather than adding security features after development. LynxOS and LynxOS-178 have been deployed in safety-critical applications worldwide.

In 2003, the company introduced the LynxOS-178 real-time operating system, a specialized version of LynxOS geared toward avionics applications that require certification to industry standards such as DO-178B. LynxOS-178 is a commercial off-the-shelf (COTS) RTOS that fully satisfies the objectives of the DO-178B level A specification and meets requirements for Integrated Modular Avionics (IMA) developers. LynxOS-178 is a native POSIX, hard real-time partitioning operating system developed and certified to FAA DO-178B/C DAL A safety standards. It is the only Commercial-off-the-Shelf (COTS) OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for re-usability in DO-178B/C certification projects. LynxOS-178 is the primary host for real-time POSIX and FACE applications within the LYNX MOSA.ic development and integration framework. LynxOS-178 satisfies the PSE 53/54 profiles for both dedicated and multi-purpose real-time as well as FACE applications.

The LynxSecure Hypervisor ("bare metal," type 1) and separation kernel was released in 2005. Within the LYNX MOSA.ic development framework, it acts as a programmable processor partitioning system leveraging hardware virtualization capabilities of modern multi-core processors to isolate computing resources.

In February 2019, Lynx announced LYNX MOSA.ic (pronounced “mosaic”). LYNX MOSA.ic is a software development framework for rapidly building security- and safety-critical software systems out of independent application modules.

History

LYNX MOSA.ic was first announced by Lynx Software Technologies in 2019. The framework was developed for integration with the U.S. Department of Defense's MOSA (Modular Open Systems Approach).

Starting in 2020, LYNX MOSA.ic is being utilized by the F-35 Joint Strike Fighter Program Office to support the development of upgraded mission system avionics for F-35 Lightning II fighter jets.

In August 2021, Lynx Software Technologies and Advantech announced a collaboration to offer Mission Critical Edge Starter Kits for IT/OT convergence through Lynx LYNX MOSA.ic for Industrial. Lynx also partnered with CODESYS Group to integrate their control automation technology into the LYNX MOSA.ic for Industrial product in August 2021. In July 2021, Lynx also partnered with Collins Aerospace, providing LYNX MOSA.ic for Avionics as the foundation for Collins Aerospace's Perigon flight computer. Lynx Software Technologies released LYNX MOSA.ic for Industrial on the Microsoft Azure marketplace in 2021.
