“…SINS/DVL integrated positioning and navigation system is the main combined system used in underwater integrated positioning and navigation at present. DVL provides real-time velocity measurement information as an external auxiliary velocity measuring instrument, combines with the parameters of SINS, inhibits the accumulation of SINS’s time integration errors, and improves the performance of navigation equipment [ 7 , 8 ]. The SINS/DVL integrated positioning and navigation system, with a high degree of autonomy, high positioning accuracy, and strong stability, will play a more important role in the development of underwater vehicle navigation technology in the future [ 9 ].…”

Underwater vehicles are key carriers for underwater inspection and operation tasks, and the successful implementation of these tasks depends on the positioning and navigation equipment with corresponding accuracy. In practice, multiple positioning and navigation devices are often combined to integrate the advantages of each equipment. Currently, the most common method for integrated navigation is combination of the Strapdown Inertial Navigation System (SINS) and Doppler Velocity Log (DVL). Various errors will occur when SINS and DVL are combined together, such as installation declination. In addition, DVL itself also has errors in the measurement of speed. These errors will affect the final accuracy of the combined positioning and navigation system. Therefore, error correction technology has great significance for underwater inspection and operation tasks. This paper takes the SINS/DVL integrated positioning and navigation system as the research object and deeply studies the DVL error correction technology in the integrated system.
