Track of the buoy and the results of array positioning using the buoy-based observation data

a Track of the moored buoy (a gray line) during continuous observation in 2016. The buoy positions during GNSS-A measurement are represented by red or blue circles, classified according to the position inside or outside the array, respectively. The circles and crosses in Fig. 4b–d show estimated array positions relative to the array center for each ping when all six PXPs responded. b Map view in horizontal direction, c time series of EW component, and d time series of NS component of estimated array positions
