Transducer’s installation error is not negligible and has to be calibrated to realize carrier’s dead-reckoning navigation for acoustic Doppler velocity log(DVL).This installation error is caused from the differences of the direction between acoustic transducer and carrier.With the aid of information from an external high precision GPS and attitude sensor
this installation error can be calibrated by the least square method for this microsystems.Theoretical analysis and experimental results show that this method can correct installation error effectively
