Comparison of the vertical accuracy of satellite-based correction service and the ppk gnss method for obtaining sensor positions on a multibeam bathymetric survey

HIGHLIGHTS

• What: Aiming to develop an alternative that could collaborate to reduce the nonuse of hydrographic surveys, this research compares two positioning methods by GNSS to improve the precision and final bathymetric accuracy. The authors describe further details of the survey in which data were simultaneously collected for both survey methods. The study showed that in the most homogeneous areas, the two methods were efficient and did not result in great disparities in the levels of difference for each positioning method.
• Who: Walmor Pereira de Andrade Neto from the CE EU have published the article: Comparison . . .
