Horizontal Accuracy Issues During MBES Surveys

Abstract

High-resolution Multibeam Echosounder shallow water surveys should not be performed with DGPS (Differential Global Positioning System), especially where feature detection is a priority. Despite the fact that International Hydrographic Organization most demanding Special Order Specification allows for 2 meters horizontal positioning level, it poorly interacts with horizontal centimetric level nadir footprint, causing degradation of bathy-metric data.

Mems Technology Quality Requirements as Applied to Multibeam Echosounder

Abstract

Small, lightweight, power-efficient and low-cost microelectromechanical system (MEMS) inertial sensors and microcontrollers available in the market today help reduce the instability of Multibeam Sonars. Current MEMS inertial measurement units (IMUs) come in many shapes, sizes, and costs - depending on the application and performance required. Although MEMS inertial sensors offer affordable and appropriately scaled units, they are not currently capable of meeting all requirements for accurate and precise attitudes, due to their inherent measurement noise. The article presents the comparison of different MEMS technologies and their parameters regarding to the main application, namely Multibeam Echo Sounders (MBES). The quality of MEMS parameters is crucial for further MBES record-processing. The article presents the results of undertaken researches in that area, and these results are relatively positive for low-cost MEMS. The paper undertakes some vital aspect of using MEMS in the attitude and heading reference system (AHRS) context. The article presents a few aspects of MEMS gyro errors and their estimation process in the context of INS processing flow, as well as points out the main difficulties behind the INS when using a few top MEMS technologies.

Current State of Deep Ocean Bathymetric Exploration

Abstract

The paper presents current state of bathymetric survey concerning deep ocean rather than shallow areas, which are better surveyed due to safety of navigation concerns. Rules and requirements of the new challenge, called the Shell Ocean Discovery XPRIZE, became a starting point for a discussion about the possibilities of mapping large areas of the ocean using up-to-date and new technology. The amount of bathymetric data available nowadays and the current state of ocean map compilations are also discussed in the paper as a motivation to inspire the new initiatives in the deep ocean.

Subaqueous geomorphology: options, tasks, needs

to prepare a geomorphological map of the bottom, i.e. subaqueous geomorphology, are: specifying and cartometric presentation of the bottom morphology that was obtained through multibeam echosounder, with the use of a 3D grid (not of lines or measurement points) – similar to a LiDaR image on the land surface (currently LiDaR bottom measurements are only possible in shallow waters and are significantly limited by water opacity ( Nowak et al. 2015 ); specifying the bottom surface nature, associated with the morphology and the lithological variation in surface
