Abstract�� Central processing unit(CPU) of embeded flight control and navigation systems was designed in a certain type of coaxial unmanned helicopter by two microcontrollers based on advanced RISC machine(ARM), together with power source and servo signal processing module, signal processing and interface module, to form a highly integrated embedded flight control and navigation computer. It was provided by 8-way asynchronous serial communications interfaces, 8 digital signal ports, connected with integrated navigation equipment, signal conditioning device, radio receiver and transmitter, attitude stabilization system with the steering gear, and other peripheral devices, to constitute a complete set of embeded flight control and navigation systems of coaxial unmanned helicopter, and configure another 16�NMB flash eeprom(FLASH) for mission and flight data storage, the flight control and autonomous navigation software of system was developed based on ARM developer suite(ADS) integrated development environment .It is proved that running state of system is good by testing and debugging in ground.
