摘要
提出了一种捷联式惯性测量单元的设计与实现方法。该系统以开环光纤陀螺和硅微加速度计作为惯性敏感元件,采用高速DSP作为中央处理器实现数据采集、处理及输出。重点介绍了系统的数据采集模块、处理模块、通讯模块等硬件电路及相应软件的设计。系统通过转台实验进行了离线标定及在线补偿,测试结果表明:系统在功能、精度以及实时性等方面达到了预期的设计目标。
This paper presents a design and realization method of Strapdown Inertial Measurement Unit (SIMU) using open-loop fiber optic gyroscopes (FOG) and MEMS accelerometers. A high-speed digital signal processor (DSP) is used to carry out data acquisition, digital signal processing, and result output. The design of system hardware and software is presented in detail. The off-line calibration and on-line compensation have been clone in the turntable test, and the result shows that the design requirement is achieved.
