针对捷联惯性系统中陀螺仪的动态测量范围很宽的要求，设计了一种高精度、宽量程的数据采集器，该系统由采集板、多功能板和通讯监听、纠错单元三部分组成，采用双口ＲＡＭ实现现场数据采集与远程导航计算机的高速通讯，可靠性好，解决了捷联惯性系统中数据采集传输与姿态运算的时间冲突问题
Aiming at the requirement of wide dynamic range of the gyroscope in strapdown inertial system, a high accuracy and wide range data acquisition system is designed. The system consists of acquisition board, multi-function board and communication monitoring and error correction unit , Dual-port RAM to achieve field data acquisition and remote navigation computer’s high-speed communication, reliability is good, to solve the strapdown inertial system data acquisition and transmission and gesture computing time conflict
