Surely , the inertial navigation has high precision , but it is also costly . acoustic tracking location is not a good way for voyage a long distance 惯性导航系统精度高,但设备昂贵,水声定位系统不适合机器人长航时的导航定位。
Usually , there are three available accesses for location underwater , inertial navigation , dead reckoning navigation , acoustic tracking location 从目前来看,应用于水下导航的方法主要有:惯性导航、船位推算导航、水声定位系统等方法。
Utts is an underwater acoustic tracking system which may operate either synchronously and asynchronously . its main task is to track and locate multiple underwater maneuvering targets accurately 水下目标跟踪系统是一个同步与异步工作方式兼容的水声跟踪定位系统,主要任务是精确跟踪和定位多个水下运动目标。
