WebUSBL (ultra-short baseline, also sometimes known as SSBL for “Super Short Base Line”) is a method of underwater acoustic positioning. It is used to track subsea targets such as ROVs/AUVs or divers. It can also be used as a mean of position referencing for surface … WebNov 1, 2024 · A robust Kalman filtering algorithm for the SINS/USBL model was proposed. The robust filter reconstructs a linear recursive model by using a delay system model, and the maximum correntropy criterion is introduced to obtain the optimal estimation. The performance of the MCDKF algorithm was confirmed by simulation and experiment.
