The tradition guidance-control system of winged missile has many flaws, such as low basic reliability, low reusable of the software and hardware, and high cost of maintenance. This paper accomplish the elementary research with the design technology of integrated guidance-control (IGC) system for winged missile from the aspect of the software integration, function integration and structure integration. With the design idea of the integration and modularization, use the computer architecture basis of the high-powered microprocessor and data bus, collocate the high real-time partition operating system, coordinate the hardware resources, design the integrated missile-borne guidance-control system with the light weight, low cost and high basic dependability. This system has been successfully implemented in the certain type winged missile.
