摘　　要： 勘察人员在海洋地质勘察测量放样时,采用的定位导航设备通常是分体式信标机。分体式信标机主要由天线头、电缆、主机、数据线电源线、计算机和电瓶6大部件连接组成。在实际生产时,连接天线头和主机的电缆经常受到海水腐蚀而损坏,应用过程中经常需要搬运诸多装备,尤其风浪较大时候,操作过程烦琐且不安全,经市场调查,国内尚无专门的主机-天线一体化信标机。在此背景下,勘察处计划开发一款便携、操作方便的一体化信标机来解决上述问题,该系统不需要架设基站,并通过信标来发射差分信号,在离岸较远的海域使用星站差分服务提供高精度位置结果。经测试验证发现满足工程精度要求,提高海上定位的效率和安全性。 The commonly used positioning navigation device is split beacon for surveyors during marine geological survey. The split beacon is composed of antenna head,cable,main unit,date line,computer and generator. But the cable which connecting the antenna head and main unit is often damaged by sea water corrosion in practical work,besides,these accessories have to be moved,the process of operation is tedious,and unsafe especially in stormy wave. After the research it is found that there is no Host-Antenna integrated beacon machine in domestic,so released the integrated beacon that need not to set up base station,transmit differential signal by beacon,and also can be used in far offshore water through satellite station differential service to support the location information. The test results show that it meets the requirements of engineering accuracy and improves the efficiency and safety of maritime positioning.
