From November 14 to November 29, 2019, the company team carried out a 15-day sea test mission in the East China Sea on a certain type of scientific research ship, and tested the multiple functions of the PX-324 AUV independently developed and produced by the company. The test results show that the indicators of PX-324 AUV are comparable to the international advanced level. At the same time, the PX-324AUV is equipped with side-scan sonar sensors, and has collected a large number of seabed geomorphic data, which verifies the data-driven function. This function can greatly improve the efficiency of seabed target scanning and recognition, and has high application value in the fields of seabed landform exploration and underwater collection.
