With more than 16 years of RTOS industry experience, LynuxWorks combines hard real-time embedded technology with broad conformance to open standards such as Linux, POSIX and UNIX to enable developers to build products that meet the most stringent requirements for real-time mission-critical applications, while at the same time take advantage of the time-to-market and investment-protection benefits of open standards-based development.

Aeronix, a major supplier of critical communications equipment to customers in the government and military, selected LynxOS because of its use of open standards, specifically POSIX, in providing a compatibility roadmap towards the Common Criteria EAL-7 security, which is the highest level of security.

POSIX, or Portable Operating System Interface, is a worldwide-accepted open operating interface standard. Support of the POSIX open standard is increasingly being mandated for commercial applications and government contracts because it assures application portability, software reuse and interoperability between embedded systems, decreasing the time and costs in getting products to market.

In addition to POSIX, LynxOS offers a FreeBSD advanced networking stack that enables Aeronix to prototype their applications in a commercial desktop environment that readily incorporates open tools and applications. FreeBSD is an advanced operating system for x86 compatible, AMD64, Alpha, IA-64, PC-98 and UltraSPARC architectures. FreeBSD offers advanced networking, performance, security and compatibility features that are still lacking in other well-known commercial operating systems today.

As part of LynuxWorks' long-standing commitment to open standards support, its entire product line is POSIX conformant and capable of running Linux applications, including its flagship LynxOS RTOS, LynxOS-178, and BlueCat Linux. With hardware capabilities spanning satellite, airborne and ground applications, Aeronix recognized that using software based on open standards would play a critical role migrating its future critical applications to new software being developed for higher levels of security.

"The winning combination of POSIX and a high-level networking stack put LynxOS ahead of the competition and provides us a clear technical advantage," said Dave Squires, systems engineer of Aeronix, Inc. "With our commitment in offering the most secure products for the military and government, we saw the value in LynuxWorks' development of a Common Criteria EAL-7 secure OS.

By choosing to use a POSIX conformant OS such as LynxOS, the path towards achieving EAL-7 assurance will be seamless and lead to lower development costs and faster time to market availability when EAL-7 technology is available."

"We continue to see that military and government customers such as Aeronix are overlooking non open standards-based software in favor of Linux and POSIX," said Sonia Leal, product manager for LynuxWorks. "Our commitment to POSIX has spanned more than 16 years and extends throughout our entire product line to enable our customers to take advantage of open standards benefits such as portability, interoperability and time to market."
