摘　　要：采用双船模式进行地震资料采集是海洋地球物理勘探一种有效的作业方法。作业中对双船的精确导航定位及实时控制与状态调整是这一方法获得高品质地震数据的关键。根据海上双船地震作业导航定位特点,采用"框架+插件"体系结构,开发设计"双船地震实时状态观测系统",实现了对双船作业的实时状态监控及视图化管理功能,并依据偏移量对双船的航速与航向进行及时调整直至使之近于同步。系统的应用使导航定位的精度控制在误差范围之内,保证了野外采集数据的质量。It is an effective marine geophysical prospecting method to acquire seismic data by dual-vessel mode. The quality of seismic data depends distinctly on the accuracy of the navigation positioning, real-time control and state adjustment of the two vessels.Based on the requirements of the navigation and positioning in the dual-vessel seismic exploration, a dual-vessel real-time state controlling system is designed using ＂framework and plug-in＂ architecture.The system achieves the state controlling of two vessels in real time and visual management, according to which, the operator can adjust the vessels＂ speed and heading timely up to almost synchronization of the advancement.The application of the system makes the accuracy of navigation and positioning exist within the margin of error, which ensures the high quality of raw data.
