tailieunhanh - Improved hydrographic surveying accuracy with the use of GPS/IMU and single beam echo sounder
Single beam echo sounders (SBES) mounted on unmanned surface vehicles (USVs) are widely used in hydrographic surveying, particularly for detecting water depth and digital depth mapping, among other things. Because of conditions such as ocean waves, the relative level arm of each component, and errors in each component device, using only SBES and GPS sensors leads to significant errors and poor accuracy. Now the SBES sensor's accuracy has improved. |
