Results from the positioning tests conducted in the definitive acoustic array. Upper panels show the positions in filtered (points) and raw (crosses) datasets. Lower panels show the position and trajectories obtained after applying the Continuous-Time Correlated Random Walk (CTCRW) movement model. Colours of points or lines represent different JSATS AMT transmitters. For fixed tests, only positions corresponding to the tests performed on one single day are shown. In the plots corresponding to drift and towed tests, the thick magenta line represents the average CTCRW trajectory for all the transmitters
