Abstract: In two-vessel seismic exploration, it is important to control the two-vessel distance and show the cable shape in a real-time way. This paper introduces the basic method and implementation process of the double vessel real-time status observing system in detail, and establishes the warning model for two-vessel distance controlling by studying the inverse solution model of geodetic problem on great ellipse nautical method. The architecture of the system is designed with the plug-in technology. Based on the platforms of.NET Framework and Arc GIS Engine SDK, and by using the mechanisms of plug-in interface customization, plug-in dynamic loading and plug-in messaging, the system has realized 8 functional modules, including the project management, device management,measuring-line management, real-time status monitoring, configurations, common tools, modes and two-vessel view management. The system has 6 views, consisting of the normal view, offset view, cable view, distance controlling view, two-vessel monitoring view and two-vessel text view. According to the results of sea trials, the system can effectively control the two-vessel distance and show the cable shape in a real-time way, with a capability of stable and long-duration operating, thus significantly improving the quality and precision of collected data in seismic exploration.
