To solve the submerged body posture information in real time underwater acoustic telemetry problems,we designed a simple and reliable method for three-dimensional data acquisition attitude. Which take full account of the specific requirements of the actual installation environment and power, and size,based on the use MTi miniature three-dimensional attitude measurement system,as underwater vehicle body posture parameters measuring devices,with the underwater acoustic telemetry system imple-mentation of Underwater Vehicle attitude information in real-time remote telemetry. The use of vessels static and dynamic tests,test results show that the method is simple,easy to use,the economy is good, and without trial before calibration,with a high practical value.%为解决水下航行体姿态信息实时水声遥测问题,设计一种简单可靠的三维姿态数据获取方法.该方法在充分考虑实际安装环境及功耗、尺寸等具体要求的基础上,采用MTi微型三维姿态测量系统,作为水下航行体的姿态参数测量装置,配合水声遥测系统实现水下航行体的姿态信息实时远程遥测.利用船只进行了静态、动态试验,试验结果表明,该方法结构简单、使用方便、经济性好,且无需试前校准,具有较高的工程实用价值.
