4D Nav experts can assist your operations by providing analysis services of complex position-related problems and data. We have the tools, experience and staff required to generate detailed pre-analysis error budgets or to forensically dig into your data to remedy difficult data anomalies. We have an intimate understanding of the acoustic and other measurement systems used for underwater construction and can reconstruct a survey through careful reprocessing of raw data. Our metrology systems experience ranges from development of acoustic-metrology smoothing software through to construction of underwater free-running metrology hardware. We can model the catenary of anchor and riser lines as well as the touchdown position of a pipeline during installation.
