The LynxOS® RTOS is the only POSIX®-conformant RTOS that is Linux ABI-compatible. An open-standards operating system such as the LynxOS RTOS must be used as the operating system in all new U.S. Navy systems, according to the Naval Open Architecture (OA)—to ensure future system interoperability and to support software reuse.

The LynxOS RTOS was certified as Category 3-compliant for the former Navy Open Architecture Computing Environment (OACE), whose key tenets have since been incorporated into the DoD IT Standards Registry (DISR)—the online repository of IT standards formerly captured in the Joint Technical Architecture (JTA).

WHAT IS U.S. NAVAL OPEN ARCHITECTURE ?

The official definition of Naval Open Architecture is, “the confluence of business and technical practices yielding modular, interoperable systems that adhere to open standards with published interfaces. OA delivers increased warfighting capabilities in a shorter time at reduced cost.”

Key Open Architecture principles include:

  • Modular design and design disclosure
  • Reusable application software
  • Interoperable joint warfighting applications and secure information exchange
  • Life-cycle affordability
  • Encouraging competition and collaboration through development of alternative solutions and sources

LYNX SOFTWARE TECHNOLOGIES OPERATING SYSTEMS PROVE THEMSELVES EVERY DAY IN NUMEROUS NAVAL OPEN ARCHITECTURE PROGRAMS:

Both the Naval OA initiative and the Weapons Systems Common Operating Environment (WSCOE), rely on the hard, real-time deterministic capabilities of the LynxOS real-time operating system to satisfy their rigorous system requirements.
