Multibeam System Accuracy, State of the Art and Future Trends

摘要

High absolute accuracy in repeated surveys is a key issue for wide swath bathymetry systems.rnHow does outer beams compare with center beams?rnThe practical methods for actually proving absolute system accuracies are discussed and testrnresults are shown to prove actual system accuracies throughout the swath.rnAlso discussed are how these methods can be applied to standard calibration procedures tornsecure the quality of the survey.rnThe technical innovation in swath bathymetry has been significant over in the last 5 years. Whatrnare the trends in the technology and how can it secure your investment?rnThese are not easy questions, but obvious mistakes can be avoided.
