| 摘 要： | 针对一种基于DSP+FPGA+MCU多处理器计算机平台的弹载组合导航系统设计了精确有效的信息同步的方法,采用GPS接收机提供的1PPS脉冲和MCU提供的脉冲信号实现GPS和SINS信号时间上的同步,采用杆臂校正算法完成了GPS和SINS测量信号空间上的同步.由于系统噪声难于准确统计,因此采用自适应卡尔曼滤波算法进行数据融合.最后对系统进行了跑车试验,试验结果表明系统所采用的方法具有较好的效果.

| Abstract: | In order to meet the requirements of integrated navigation system which is based on a computer of DSP+FPGA+MCU multiprocessor platform and is used in guidance munitions, effective data synchronization methods are designed. In these methods, 1PPS signal from GPS receiver and pulses from MCU are used to realize information synchronization of GPS and SINS in time, meanwhile lever-arm compensated algorithms are designed to realize information synchronization in space. Because of the difficulty to present the MIMU system noise accurately, an adaptive Kalman filtering algorithm is designed. In the end, the excellent result of the vehicle experiment indicates that the system design methods are successful. |
