Bias estimation of acoustic transducer position for seafloor geodetic observation
Among results of JCG’s intensive observation off Miyagi Prefecture, some epochs gave erroneous solutions presumably caused by the bias of acoustic transducer position. We tried simultaneous estimation of the bias of acoustic transducer installation and positions of the seafloor reference points. As a result, we detected significant biases dependent upon difference of used devices i.e. acoustic transducers, observation poles, etc. Correction for these biases gave less scattered time‐series of determined positions and reduced residuals of traveltime. This method took effect to improve the accuracy of position estimation of seafloor reference points.
