基于北斗卫星的海洋调查测量系统时统技术

摘要

海洋调查测量船上各作业设备间缺少统一的时间基准,极大影响了调查测量作业成果质量.针对这一问题,根据北斗系统授时原理,利用网络时间同步协议设计了适用于海洋调查测量系统的时间同步系统,实现了所有调查测量设备时间的统一.实际试验结果表明,该同步系统性能可靠、对保证调查测量数据质量起到关键作用.%There is no uniform time standard in the survey equipment,which affects the quality of the operating results.The time synchronization system of survey equipment is designed based on the principle of Beidou timing mode and NTP,and the unity of time is realized in the survey equipment.Experimental results illuminates that it is entirely feasible to use Beidou time synchronization system in the survey equipment.
