The Processing parameters tab has three tabs for setting parameters:

  • Sources
    Define the sources for the processing dependent on the hardware and datagram content. For example define if the XYZ coordinates shall be calculated from the Swath data (depth data) or from the Range data. Or define if the heading value should be applied from the depth datagram, motion sensor datagram, a position datagram or be replaced by input from an external file.

  • Swath Data 
    Will turn on and off use of offset parameters and motion sensor values for depth (swath) datagrams. Often the swath data are corrected for all motions when they are saved as x, y and depth values relative to the ship position. If the survey line file does not contain any depth datagram, this tab will not be available.

  • Range Data
    Will turn on and off use of offset parameters and motion sensor values for range datagrams. Will be used if the source for XYZ conversion source is set to Range Data. The range data are the time measurements from the transmitter and back to the receiver. The processing to xyz involves all the mounting offsets, the motion sensor values, the sound velocity data and the tide data. If the survey line file does not contain any range datagram, this tab will not be available.

 

The Standard deviation parameters tab

Image Added

The Standard deviation parameters tab in the Edit Vessel Configuration dialog.

The standard deviations parameters are used in the CUBE command and in the calculation of horizontal and vertical uncertainties.

In hydrography the term TPU (Total Propagated Uncertainty) is defined. It is composed of a horizontal component (THU = Total Horizontal Uncertainty) and a vertical component TVU (Total Vertical Uncertainty).


The Standard deviation parameters tab has three other tabs:

  •  Direct offsets: Contains values like GPS and errors IMU errors.
  • Measurmement accuracies: Standard deviation values for motion sensor, sound velocity etc. 
  • Other components: Accuracy of other types of measurements.

 

The values in the three tabs will contribute to the THU, TVU and then TPU.

Info

The changes in the standard deviation parameter values will not contribute in the processing of the final xyz position for the soundings, just the uncerainties.

 


Create new vessel configuration


A new vessel configuration can be created by copying an existing configuration inside the same project or copy from another. By right clicking a vessel configuration in the project named Course, for example Kongsberg em710, and select Create copy in > Course.

A new configuration named Kongsberg em710 (1) will be created. Then rightclick the new configuration and select Rename and then give the configuration a proper name, for example Kongsberg em710 new.
