摘要
高精度的位置与姿态遥测技术已成为航行潜器与水下平台衔接的必要手段,而常规的无线电测距和红外遥测技术都难以克服能量在水中迅速衰减、作用距离受限的缺陷。针对该问题,设计了基于声学定位和姿态遥测技术的微型位姿遥测系统,通过高精度的声学测距和位姿解算,实现了航行潜器和目标平台之间的远程引导和精确衔接。试验数据表明:水下微型位姿遥测系统具备高质量的测量和引导性能,相对位置遥测和相对姿态测量精度分别达到5 cm和3°,具有良好的工程应用价值。
The technology of high-precision positioning and attitude telemetry has become an important method for submarine and underwater platform connecting,while conventional technology such as radio distance measuring and infrared remote sensing technology are difficult to overcome the problem of operating distance is limited and quick attenuation of energy in water.To solve this problem,design a system of underwater positioning and attitude telemetry system based on acoustic positioning and attitude telemetry,and by high-precision acoustic ranging and position and attitude solution,realize remote boot and precise connection between submarine and target platform.Experimental datas show that this system has high-precision measurement and boot performance,the relative positioning telemetry is 5 cm and relative attitude measurement precision is 3°,which has good engineering application value.
