Slide 4 Correcting for Sound Velocity Sound Velocity Corrections Sound Velocity Corrections Calibrated sounder with a bar check: Calibrated sounder with a bar check: No correction file is needed. No correction file is needed. Using a velocity probe: Using a velocity probe: Create a Sound Velocity Correction file (*.VEL) in the SOUND VELOCITY program. Create a Sound Velocity Correction file (*.VEL) in the SOUND VELOCITY program. Enter the name of your correction file. Enter the name of your correction file. Using fixed corrections at different depths: Using fixed corrections at different depths: No entry is needed. No entry is needed. After editing your data, run the SOUNDING ADJUSTMENT program. After editing your data, run the SOUNDING ADJUSTMENT program. Separate corrections can be computed for the high and low frequency depth values. Use Depth 1 computes an SV correction for both frequencies, using just the high frequency. Use Depth 2 computes an SV correction for both frequencies, using just the low frequency. Use Depth 2 computes an SV correction for both frequencies, using just the low frequency. Use Both, computes separate SV corrections, using the depths of the high and low frequency. Use Both, computes separate SV corrections, using the depths of the high and low frequency. Slide 5 Read Parameters: Selections Window Select the equipment to be edited.

Used to pre-filter positions and/or RTK Tides. If Quality of GPS position is less than specified: If Quality of GPS position is less than specified: Position is not usedPosition is not used (top section) RTK Tide is not computed for pointRTK Tide is not computed for point (bottom section) When positions are deleted from interior of line, new positions are interpolated and not depths are lost. When positions are deleted from the ends of a line, depth data is lost. When positions are deleted from the ends of a line, depth data is lost. Slide 10 Read Parameters: Advanced Window RTK Tides: Enable RTK Tides and Select a Method Average Tide (preferred) Averaging period = 5 wave periods (in secs.) Recalculate allows you to fix problems due to bad configurations. MRU Apply Heave: Thats why you bought it. Apply Pitch and Roll Corrections: Re-computes position of transducer using pitch and roll data. Remove Heave Drift: Tries to re-center the heave about the 0. POSPac Adjustments &amp; Post- Processed GPS Corrections Allows you to adjust positions with post- processed *.OUT and comma-separated- value files. Slide 11 RTK Tides: Tide and Draft Window Read Parameters Window Read Parameters Window Set parameters in the Advanced Tab of the Read ParametersSet parameters in the Advanced Tab of the Read Parameters Tide and Draft Window Tide and Draft Window Raw RTK Tides values:Raw RTK Tides values: Color-coded by GPS StatusColor-coded by GPS Status Averaged RTK TidesAveraged RTK Tides (RED line on graph)(RED line on graph) Eliminate RTK Tide Spikes due to short- term lost of Fixed RTK in the Tides window.Eliminate RTK Tide Spikes due to short- term lost of Fixed RTK in the Tides window. Slide 12 Correction of Heave Drift Heave values can drift off-center due to rapid accelerations or changes of direction. Heave Drift NOT Removed Heave Drift Removed Slide 13 Read Parameters: Advanced Window: Steer Sounding Beam D D X,Y The position of the sounding is based upon the center of your transducer beam. Steer Sounding Beam computes a new location for the center of your transducer beam, based on the pitch and roll values. D = cos(pitch)*cos(roll)*D. Slide 14 POSPac Adjustments Allows the user to apply enhanced Post-Processed positions, heave, pitch, roll and Tide data from a POSPac (POS/MV) file.

AVI Slide 15 SBMAX Layout SBMAX Control Window SBMAX Spreadsheet SBMAX Survey Window SBMAX Profile Window Slide 16 Other Useful Windows Echogram Window: Used to display the acoustic data for each ping from network-capable echosounders. Heave Window: Displays raw heave values. Examine each line for heave drift! Tide and Draft Window: Shows tide corrections. Very useful for RTK tides! Allows you to cut out short periods where you have lost RTK fixed. Slide 17 Editing Track Lines: SURVEY Window SURVEY Window You can delete individual bad position points OR Interpolate across user-defined blocks Edit your all of your track lines, then review the profiles one-by-one. Deleting interior positions results in no loss of depth data, as new positions are interpolated across the deleted track. Deleting exterior positions results in the loss of depth data. AVI Deleted Positions No loss of depth data Deleted Positions Loss of depth data at end of line Slide 18 Background Files in Survey Window Users can display all background files in the Survey Windows of SBMAX and MBMAX.
