摘要
使用陀螺仪的惯性导航系统具有非常高的精度,但是成本非常高昂,无陀螺捷联惯性导航系统通过对多个加速度计的数值进行解算也可以实现导航的目的,同时成本远低于使用陀螺仪的惯性导航系统。本文提出了一种基于Nios II的导航计算系统设计,通过将9个加速度计直接安装在载体上,然后通过FPGA进行计算,最终实现导航的目的,系统具有准确性高、成本低等优点。
Using gyroscope inertial navigation system has very high accuracy,but the cost is very high,no gyro strapdown inertial navigation system based on a number of accelerometer numerical calculating can also achieve the purpose of the navigation,and the cost is much lower than using gyroscope inertial navigation system. This paper proposes a use navigation system design based on Nios II,through the nine accelerometers installed directly on the carrier,and then by the FPGA,ultimately achieve the purpose of navigation,system has advantages of high accuracy,low cost.
