| Abstract: | Integrated SINS/GPS navigation system based on ARM and DSP was designed and implemented. The system adopts DSP as navigation computer to complete rapid fusion and calculation of navigation data and ARM CPU as upper level computer to corn plete the functions such as data storage, display and interface controller etc. The design was emphasized on highly accurate data acquisition of FOG and accelerometer as well as interface design between ARM and DSP. According to system hardware scheme, Kalman filter for integrated navigation was finished. Finally, field-test results show that this system can satisfy navigation precision and validate the correctness and reliability of hardware and software design. |
