Calculate the line spacing required and view the cross-section areas for a tilted multibeam sonar head. X-Axis = Positive Forward Roll = Positive as Port side goes upY-Axis = Positive…
Calculate the total time a survey will take given using a traditional (single-swath) MBES. You must enter the swath width, size of the survey area, average depth and speed of…
Calculates the resultant along-track and across-track beamwidths of a multibeam echosounder at a specific frequency using the known beamwidths at a specific reference frequency. Sonar Settings: Enter the Beamwidths of…
This tool converts a seconds-since-midnight value from the beginning of the current day or the beginning of the GPS Week and vice-versa. HYPACK HSX file observations are seconds-since-midnight of the…
This calculator has been superseded by a new page (link below) that calculates Line Spacing for all three Patch Tests when using a tilted head. https://mosaichydro.com/mbes-patch-test-tilted-head-line-spacing-calculator/
This tool calculates the number of sonar hits (beams or soundings) in a user-specified square grid cell based on Swath Width, Sonar Range, Sonar Altitude, Speed of Advance, and Ping…
This tool calculates the resultant lever arm (shifted port/stbd & up/down) after rotating the sonar on a tilt adapter. Start with your current lever arm and the vertical distance from…
This tool calculates two sets of line-pair spacings to reduce the data acquisition time compared to running lines with a set line spacing by over 35%. Referring to the diagram…
This tool will determine the distance between the Yaw test lines to achieve the desired overlap at the minimum depth. Enter the minimum Altitude/Depth along the Yaw Lines, the swath…
This tool will calculate the Total Swath for a given depth (sonar altitude) and Swath Angle. Enter the sonar altitude (depth) and your swath in degrees. The calculation will give…
