Low-cost Integrated Navigation System Based on ARM and FPGA Design

针对采用光纤陀螺、激光陀螺和石英挠性加速度计等设计的组合导航系统成本较高,而MEMS惯性器件低成本的特点,文中采用VTI的MEMS组合式传感器SCC1300-D04外加嵌入式调理芯片ARM和FPGA、GPS接收机进行组合导航系统低成本设计;SCC1300-D04器件包含一个轴向的MEMS陀螺和加速度计,成本较低、性能良好的特点广泛应用于各种车载民用导航领域;文中详细介绍了组合导航系统的各个模块的组成,重点介绍GPS接收机的配置、FPGA和ARM芯片STM32F415RG之间的数据通信以及MEMS传感器硬件电路的设计,最后通过试验验证设计的正确性。

For integrated navigation system designed for fiber optic gyro, laser gyro and quartz flexible accelerometer higher costs, while low--cost MEMS inertial devices, this article uses VTI＇s MEMS modular sensor SCC1300--D04 plus embedded conditioning chipARM and FPGA, GPS receiver to design low--cost integrated navigation system. SCC1300--D04 device contains an axial MEMS gyroscope and aceelerometer, low cost, good performance characteristics are widely used in various civilian vehicle navigation field. This paper describes the composition of the various modules of the integrated navigation system, and focuses on the configuration of the GPS receiver the FPGAs and ARM chip STM32F415RG in between data communication and MEMS sensor hardware circuit design, and finally through the test to verify the correctness of the design.
