| 摘 要： | 时间同步误差是多波束测量的一个重要误差源.因此,在进行多波束海底地形测量时,一般都利用GPS的1PPS信号来实现精确的时间同步.介绍了1PPS信号,分析了多波束测深系统的时间同步原理,以及在没有1PPS同步的情况下,后处理时应注意的事项.最后对野外资料采集提出了相应的建议. |
| 关 键 词： | 多波束测深 秒脉冲 时间同步 时标 |

| Abstract: | Time synchronization error is one of the critical error sources in multibeam echosounding survey.Therefore,when carrying on multibeam seabed topography survey,it generally uses GPS＇s 1PPS signal to achieve accurate time synchronization.This article introduces the 1PPS signal and an analysis of multibeam echosounding system time synchronization principles.In the condition of the absence of synchronized 1PPS,the operator should pay attention to post-processing.Finally the paper gives some recommendations to the field data acquisition. |
| Keywords: | multibeam echosounding 1PPS synchronization time stamp |
