Real-Time Operating System for Reliable and Trustworthy Systems

RTWORKS is the real-time operating system (RTOS) programmed by Korean engineers which is compliant with DO-178B Level A, the highest technical standards of the FAA. It is the first software embedded in flight control computers that passed flight tests in Korea. Supporting the avionics SW standards (ARINC 653), it prevents inter-application error transfer at the source, enabling successful integration of application with varied criticality into a single computer to address the size, weight and power (SWaP) issue of air vehicle.
It supports AUTOSAR BSW, an automotive standard, and the PnP and networking powered by inter-ECU services based on SOME/IP & SD. RTst also provides professional engineering services by kernel developers, enabling creation of kernel with maximum system performance and reduction of time-to-market while sharpening the competitive edge of embedded system products.
