The leveling device and the level bubble installed therein make the side-scan sonar positioning center, the rod axis and the GPS phase center stay on a vertical line through leveling, and the GPS plane coordinates are consistent with the towed fish center coordinates. The output GPS receiver coordinates are directly used as the towed fish's own reference coordinates for locating underwater targets, avoiding the dynamic changes of the traditional flexible towed GPS receiver and the towed fish position. The coordinates are only measured and estimated to generate errors, which greatly improves the underwater positioning accuracy of the side-scan sonar.
