摘　　要：北斗船载终端可提供船舶定位报告、北斗短报文通信、应急报警、船舶沉没预警等多种功能。该系统可以在落入水中后准确地控制释放深度,可以对船只进行导航和定位,可以通过该系统对船只进行定时报告,从而达到对船只的位置进行预警的目的。装备了北斗卫星的船只,不但能够增强船只与岸边之间信息交流的实时性与客观性,为船只的航行管理提供有力的技术支持,还能够在恶劣的天气、复杂的航道条件下,对船只的位置进行实时监控,从而获得准确的航行信息。文章主要研究了船载终端系统的主要功能,串口通信的关键技术以及相关的数据处理,从而提高系统的定位精度,并克服了没有基站的问题,提高了系统的可靠性,扩大了信号的覆盖范围。Beidou shipboard terminal can provide ship positioning report,Beidou short message communication,emergency alarm,ship sinking warning and other functions.The system can accurately control the release depth after falling into the water,in general,the ship can be navigated and positioned,the ship can be reported regularly through the system,when the ship is in danger or submerged,the system can also be in danger or submerged in the case of automatic release,so as to achieve the purpose of early warning of the ship’s position.Ships equipped with Beidou satellites can not only enhance the real-time and objective information exchange between ships and the shore,and provide strong technical support for the navigation management of ships,but also monitor the position of ships in real time under bad weather and complex channel conditions,so as to obtain accurate navigation information,so as to effectively avoid reefs and shoals,enhanced the navigation safety of ships.
