The aerospace controls division of BAE Systems plc, Farnborough, U.K., has introduced a new version of its real-time operating system for use in aircraft, called CsLEOS (originally called the Control Systems Layered Embedded Operating System). This fault-tolerant operating system now provides support for graphical user interfaces. It also adheres to the DO-178B standards set by the Radio Technical Commission for Aeronautics to qualify flight critical software.
BAE's operating system would help integrators building systems for the Joint Tactical Radio System project, said Milan Dedek, CsLEOS product manager. JTRS is the Defense Department's next integrated generation radio system for all the services. CsLEOS loads applications independently from one another, so adding new programs to a system run by CsLEOS won't necessitate recompiling or retesting the entire operating system. The result is development costs are reduced for new software.
