一种捷联惯性导航系统设计

The Design of a Class of Strapdown Inertial Navigation System

采用加速度计和陀螺仪设计了一种捷联惯性导航系统,通过测量导航载体三个方向上的所需数据,设计导航控制算法、加速度传感器和速率陀螺仪的信号调理电路,提高了传感器数据的有效性。传感器的输出信号经由A/D转换器转换信号传递给单片机做数据处理,再将数据传送给都导航计算机,完成系统的实时导航。

This paper describes the design of a strapdown inertial navigation system using accelerometer and gyroscope,through the data needed to measure navigation carrier in three directions,the design of navigation control algorithm,the acceleration sensor and the gyro signal conditioning circuit,the efficiency of sensor data is improved.The output signal of the sensor is transmitted to the single chip microcomputer through the A/D converter to do the data processing,and then the data is transmitted to both the navigation computer,and the real-time navigation of the system is completed.
