Long baseline positioning system, referred to as LBL,is a kind of high precise deep underwater posi?tioning system. Based on analyzing the development situations of LBL, the positioning theory and method were stud?ied systematically according to the experiment in Songhua lake, and the problems of seabed beacons laying, fixation and recycle in 50 m water depth were solved in this paper. Then relative calibration (baseline calibration) method and absolute calibration (box?in) were explored, and the tracking and positioning mode of localizer was determined. An integrated system and a positioning process of LBL were formed, and the high precise underwater positioning da?ta were obtained.
