LynxOS ( Lynx O perating S ystem ) is a unixoides real-time operating system of the Californian company Lynx Software Technologies, which primarily on the market of embedded systems is aligned.

Although the application areas include predominantly critical applications in military, aerospace and aerospace , medical, industrial process and control systems as well as telecommunications and consumer electronics.


Under the name Lynx Real Time Systems , the company developed a first version for the Motorola 68010 architecture in Dallas in 1986 and thus also the first fully POSIX- compatible real-time system .

Between 1988 and 1989 LynxOS was ported to the Intel 80386 platform and finally in 1989 it received full ABI compatibility with UNIX System V Release 3 and from Version 4.0 with Linux .

In 2003, the further development was divided into the main branch LynxOS and the secondary branch LynxOS-178 , which meets the special requirements of avionics and guarantees certifiability according to DO-178B . For this purpose, it fulfills the formal requirements for SW Requirement Process, SW Design Process, SW Coding Process & SW Integration Process as well as the functional requirements for error isolation, which correspond to the requirements for the SW architecture.


Some basic features of the system are:
