国外潜航器水下隐蔽导航定位方法探析

针对潜航器自主惯性导航误差随时间不断增大的问题，研究了基于运载器、信标中继、海底固定基站的国外潜航器的典型导航定位方法。通过水声通信方式，运载器、信标中继站将其卫星精确定位数据发送至潜航器，或海底固定基站接收到潜航器发射唤醒信号后，量测相关信息并发至潜航器。潜航器被动接收水声通信数据，并对其进行综合处理，实现潜航器在水下隐蔽工作模式下对自身位置的实时修正，提高潜航器导航定位精度，具备较强的工程可实现性。

Discussion on the Abroad Unmanned Vehicles Covert Navigation and P osition Method in the Underwater Mode

Focusing on the unmanned underwater vehicles navigation error continuously increasing with time problem, abroad unmanned underwater vehicles position method based on the carrier?flats, buoy relay stations and a single seafloor sta?tion is discussed and analyzed in this paper. By underwater acoustic communication method, the accurate positioning data are sent to the unmanned underwater vehicle by carrier?flats or buoy relay stations. Moreover when unmanned vehicle sends a sin?gle ping signal, the single seafloor station receives, processes correlative information and then sends it to the unmanned vehi?cle. The information is received and processed synthetically by the underwater vehicle in the covert working mode, which can correct the underwater vehicle?s position in real time and improve the vehicle?s navigation accuracy. The method has a good performance and can be realized easily.
