Real Time Kinematic (RTK) heave as a replacement of Motion Reference Unit (MRU) heave in hydrographic surveying works
Heave is one of the major contributors to errors in water depth measurements.Motion Reference Unit (MRU) measures the heave signal with high-level accuracy as well as other ship motions.Unfortunately, MRU has been reported to have some of drawbacks such as; heave drift error, influence of ship motion dynamic, In addition to its very expensive Phone
