Select the Multibeam System
Select the Positioning System
Select the Attitude System
Select the Draft Sensor
Select the Tide reduction source
The tide model source of error is based on the estimation of uncertainty from tide zoning.
The squat model source of error is based how well you have modelled the vessel squat. For Ellipsoidal reduction set to zero.
Select the full opening angular sector for the sonar, eg 180 degrees for horizon to horizon
Select the pings per second rate. Set to -1 for automatic as fast as possible
Select the Swath Coverage, 100% for FULL Bathymetric Coverage, 200% for Full Seafloor Coverage. For Order 1a set to 110%
Select the Minimum Depth for the survey. This is used to bracket the computations.
Select the Maximum Depth for the survey. This is used to bracket the computations.
Vessel speed has a direct impact on data density and feature detection capability.
The Mean SV for water column is used to compute the THU and TVU on outer beams. This only needs to be approximate for the area of operation.
Acceptable SVP error arises from observing SVP in one location and them moving to a different water body, tide cycle.
The maximum operational PITCH impacts most notebly on outer beams for both TVU and THU.
The maximum operational ROLL impacts most notebly on outer beams for both TVU and THU.
The maximum operational HEAVE impacts the entire ping for TVU.
Uncertainy associated with an imperfect patch test affects both THU and TVU.
Uncertainy associated with an imperfect patch test affects both THU and TVU.
The GNSS antenna installation accurcay is source of error for lever arm computations contributing to both THU and TVU.
The Antenna to MBES offset impacts both TVU and THU. sign does not matter
The Antenna to MBES offset impacts both TVU and THU. sign does not matter
The Antenna to MBES offset impacts both TVU and THU via offset errors. Its always good to minimise these. sign does not matter
The IMU to MBES offset creates lever arm sources of error. Its always good to minimise these.
The IMU to MBES offset creates lever arm sources of error. Its always good to minimise these.
