Methods and devices are configured to maintain a planned arrangement of autonomous underwater vehicles (AUVs). An AUV performs a corrective motion to adjust its current position relative to other AUVs emitting signals, so that the AUV's corrected position matches a planned position of the AUV in the planned arrangement better than its current position. The corrective motion is determined based on the location of the AUVs whose emitted signals are detected by the AUV.

Method and autonomous underwater vehicle able to maintain a planned arrangement

Location of underwater moving target device carrying a receiver configured to detect acoustic waves emitted at a known location is estimated such that to be consistent with detected velocity and orientation of the target device, and with a current phase of a signal corresponding to the acoustic waves detected at the target device. A stack including one or more boxes obtained by applying contractors to location boxes is output as the estimate of the location of the moving target device.
