The application of ultra-short baseline(USBL)in OBN positioning
OBN is becoming the mainstream method for OBS Marine seismic acquisition in deep water due to its independent acquisition characteristics.OBN point positioning accuracy is one of the main factors that determine the quality of seismic data.This paper mainly introduces the working principle and working process of the ultra-short baseline(USBL)of the new acoustic positioning system,as well as its application methods and application effects in OBN operations.
