Abstract :
Honeywell has developed the Embedded Computer Toolbox and Operating System (ECTOS), a reusable software approach for design and development of applications for use in aircraft navigation systems, land-based navigation systems, and navigation, guidance, and control of unmanned air vehicles (UAVs), missiles, standoff weapons, and munitions. ECTOS provides the user with a custom Ada run-time system, tasking executive, I/O drivers, built-in-test (BIT), navigation and Kalman filtering, and mode control. In addition, ECTOS provides the user with the Embedded Computer Toolbox (ECT) software, a core set of interfaces with Honeywell´s Embedded Computer Operating System (ECTOS), allowing the user to reduce the time required to develop application specific software and provides greater flexibility in easily accommodating various mission requirements. This paper describes the ECTOS architecture and the benefits this architecture provides Honeywell and Honeywell´s customers in the development of avionics systems. The role of ECTOS in two sample avionics developments (McDonnell Douglas Delta Clipper Experimental and Sikorsky Cypher UAV) is also described
