针对内河航运对廉价、便携导航设备的实际需求，本文设计并实现了一种基于Android的移动AIS数据显示系统.该系统可通过蓝牙无线连接船载AIS设备，从而在智能移动终端（手机或平台）上接收、解析AIS数据，并将其传递的船舶动态与电子海图进行叠加显示，实现对AIS船舶信息的实时监控和查询.利用操船者的移动设备运行该系统，即可形成一个简易的移动导航系统，满足内河众多小型船舶的航行需求.

According to the actual demand of unexpensive and portable devices for inland navigation, the paper designed and implemented a mobile AIS data display system based on android platform. The system can connect to ship carried AIS devices by Bluetooth, and enable an intelligent mobile device (phone or tablet) to receive and decode AIS data to obtain realtime information of vessels around and paint them onto electronic nautical charts. With the functions of vessel dynamic monitoring and vessel information querying, the system can act as a simple portable navigator for the ship handlers of small inland vessels by running it in their mobile devices
