Our results show that noise levels can be reduced by more than a factor of ten (20 dB) by combining averaging and reduced-rank noise suppression with custom reference filtering using in-streamer auxiliary sensors. The resulting total error, including navigation and system errors, is below 2 % for the deep target frequency range 0.1-1.0 Hz.
