This paper analyzes the shortcomings of data management systems used in previous domestic and fo-reign integrated navigation systems in ocean bottom seismic exploration,such as high software licensing costs and poor platform openness,in the subsequent development and product application promotion process.A new design scheme for a multi vessel distributed navigation system database was proposed through analysis and selection from eight aspects,such as system architecture,security,data storage procedures and transaction support,data access stability and performance,SQL compliance,ACID compliance,data synchronization methods,and sup-ported data types.A comprehensive navigation system database based on PostgreSQL was formed.Verified tests have shown that the database's access capability can cope with distributedconstruction organizations of multi ves-sel marine seismic exploration,to meet the needs of complex and challenging multi vesseloperation projects.
