Research on Underwater Multi-platform Collaborative Positioning Technology
With further development of the ocean,the demand for underwater multi-platform operation is more and more significant,and the mutual position relationship between different platforms is important to ensure the effectiveness of the operation.In this paper,the position measurement methods based on acoustic ultra-short baseline positioning technology are introduced.The acoustic propagation characteristics,positioning principle,error sources and main error models are discussed.The positioning accuracy and distance are analyzed by means of historical environmental parameters and simulation analysis.Based on the above analysis,in typical application scenarios of underwater operation with different receiving and transmitting depths,the optimal co-positioning strategy is given after analysis,which is helpful to guide underwater cooperative operation.
