Vergleichende Untersuchungen zur Lagegenauigkeit von Sonaraufnahmen im maritimen Bereich

Hochschule Neubrandenburg, 2009

Abstract: In the sea measurement or Hydrographie, depths of rivers, lakes or other watercourses are determined. This happens with single echo sounders, professional echo sounders or with Sidescan sonar. The reference to the position of the measured depths is realised with a positioning system. The position information rests predominantly on the global positioning system. For the rise of the exactness of the situation, the Differential Global Positioning System is used. In the course of these Bachelor's work the DGPS-systems Leica Ascos and Trimble Long Range were used. The work deals with the accuracy of these both systems with the professional echo sounder and the Sidescan sonar. Measuring objects which can be measured above as well as below the water were chosen.
