为了满足水下航行体的大范围水下定位跟踪测试要求,针对基于座底式水声网络节点的跟踪测试技术进行深入研究。设计了一种紧凑型水声网络节点,该节点采用卧式安装结构,可通过水声或光电信号进行回收控制,具有结构轻便、布放效率高、回收可靠等特点。利用该水声网络节点,串行布放在某水域组成座底式长基线跟踪测试系统,该系统具备定位跟踪、航行参数遥测等功能。针对其定位跟踪及航行参数遥测功能进行湖上跑船试验,试验结果证明,该系统定位跟踪精度高,航行参数遥测功能可靠,遥测误码率低,总体覆盖范围大,可广泛应用于水下航行体的定位跟踪、导航测试等,具有较高的工程实用价值。
To meet the requirements of underwater vehicle positioning and tracking tests over a wide area, an intensive research on tracking and testing technology based on the bottom-seated type of underwater acoustic network nodes has been conducted, and a compact underwater acoustic network node with a horizontal mounting structure, which can be controlled for recycling by underwater acoustic or photoelectric signals, is developed. Due to its light structure, high efficient deployment and reliable recovery are achieved. By deploying underwater acoustic network nodes on the seat bottom in series along a water zone, a long baseline tracking test system is formed, which can be used to realize location, tracking, telemetry and other navigation functions. For verifying the functions of location, tracking and telemetry, boat running tests on the lake are conducted. The test results show that the system achieves high location tracking accuracy and reliable navigational parameters telemetry at lower error code rates. The system can cover a wide operating area, so it can be widely used in underwater vehicle location tracking, navigation test and so on, with high practical engineering value.
