Abstract

The invention discloses a marine geophysical prospecting integrated navigation information playback instrument and a system. The marine geophysical prospecting integrated navigation information playback instrument comprises an upper computer and a navigation playback instrument body; the upper computer is used for acquiring navigation data acquired by a geophysical vessel in the work process. The navigation data is processed, and instrument data is acquired; the instrument data is sent to the navigation playback instrument body and comprises data capable of being processed by an integrated navigation system; the navigation playback instrument body is used for receiving the instrument data; the instrument data is sent to the integrated navigation system; trigger signals sent by a navigation signal control platform are received and comprise signals for triggering work of the geophysical vessel; the time sequence is configured according to the trigger signals, and gun control data and bird control data are sent to a navigation signal control platform and the integrated navigation system. The signals and data of all navigation equipment are played back in real time when the geophysical vessel runs, and therefore a practical navigation work scene is precisely restored.

Description

technical field [0001] The invention relates to the field of geophysical prospecting, in particular to a marine geophysical prospecting comprehensive navigation information playback instrument and system. Background technique [0002] The integrated navigation system is one of the core large-scale control systems of the geophysical exploration ship. It provides precise coordinate positioning and towline positioning for the geophysical exploration ship, and can control the acquisition system and source system. It plays an important role in post-seismic data processing and drilling positioning. [0003] Usually, in the process of marine geophysical exploration, the geophysical prospecting ship tows multiple cables to work on the sea. When it reaches the position determined by the integrated navigation system, the air gun array at the stern of the geophysical prospecting ship will activate the artificial The seismic source, and then, the seismic source signal generated by the a...
