Parent Item

System:

List with all available ADCP systems that exist in the currently selected Qinsy database.

(See General Layout Information about loading a Qinsy database).

Cell Number:

This option to select a cell number is only needed for possible selected cell sub items (e.g. Cell Number, Cell Depth, Cell Velocity)

NONE, or leave blank
ALL
The selected cell sub items will be repeated for all available cells
Enter individual cell number, and/or comma and/or hyphen (or double-dot) separated.
For example: "20-30" or "1,5,10,20-30" or "1-10,15,20-30", or "1..10, 20..30".
Lowest possible cell number is 1. The selected sub items will be repeated for each defined cell number.

Computation:

This option to select a computation is only needed for possible selected ADCP sensor location sub items (e.g. Node Easting, Node Northing, Node SOG, etc.)

The first entry is always [Priority List]
The rest of the list will show all available computations, as defined in the Computation Setup of the current Qinsy database.

Note that when the layout is used for Export (offline), you can not select entry [Priority List], you must select a 'real' computation from the list.

text

Text Format

Normal Text
Your own free plain text
Binary
Enter one or more ASCII character codes, comma or space separated, in the range between 1 and 127.
For example '2' for a binary STX character, '3' for a binary ETX character, or '13, 10' for CR+LF.
See table ASCII Codes for an overview of all possible characters.
New Line
Same as Binary but already formatted as '13, 10' (meaning CR+LF) and without a possible Field Delimiter.
A Field Delimiter may be present when your layout purpose is for Export or ASCII Logging.

Name

Name of the selected ADCP system, as defined in Db Setup.

text

Ping Time

Time of the last ping.

time

Cell Count

The number of depth cells that the current ping consist of.

integer

Cell Length

Instrument Setup setting.

The depth range for each depth cell.

double

Pings Per Ensemble

Instrument Setup setting.

Number of internal pings used for one update.

integer

Ping Number

Increasing number.

Every new ping received from the ADCP sensor will increment the ping number by one.

integer

Ping Age

The difference between the triggering time and the time of the last ping in seconds.

Note that the Age value for export will be the difference between the time of the current observation and the previous exported one.

Formula:

Online (Generic Display, Generic Output Driver, Generic ASCII Logger)
Age = Triggering time - Observation time
Offline (Generic Export)
Age = Observation time - Previous observation time

double

Beam Angle

Instrument Setup setting.

Value in degrees.

double

Coordinate System

Flag that represents the current selected coordinate system for the individual velocity values.

0 means velocities per individual beam

1 Velocities relative to the ADCP instrument (X, Y, Z direction)

2 Velocities relative to Object (Ships Starboard/Forward,Mast direction)

4 Velocities relative to Earth (Easting, Northing, Up direction)

integer

You may define a translation table in order to translate the number codes into readable text.

Node Name

Name of the node, as entered in Db Setup, for the ADCP sensor location.

text

Node Easting

The easting of the ADCP node, as calculated by the selected computation. The easting is always on Survey Datum.

double

Node Northing

The northing of the ADCP node, as calculated by the selected computation. The northing is always on Survey Datum.

double

Node Latitude

The latitude of the ADCP node, as calculated by the selected computation.

Latitude is default on Survey Datum, but WGS84 (or ITRF2008) can also be selected.

geo

Datum:

Survey Datum (default)
WGS84
Assumption is that the WGS84 (or ITRF2008) datum is part of the Geodetic Setting in DB Setup.

Node Longitude

The longitude of the ADCP node, as calculated by the selected computation.

Longitude is default on Survey Datum, but WGS84 (or ITRF2008) can also be selected.

geo

Datum:

Survey Datum (default)
WGS84
Assumption is that the WGS84 (or ITRF2008) datum is part of the Geodetic Setting in DB Setup.

Node Height

The height of the ADCP node, as calculated by the selected computation.

Height is by default on Chart Datum, but Survey Datum, WGS84 (or ITRF2008), the Actual Water Level, the Mean Water Level, or the Geoid Model Level may be selected.

double

Datum:

Survey Datum ( Name )
Height value will be on the selected survey datum ellipsoid, e.g 'ED50'.
Note that Survey datum (or Horizontal Datum) is set in the Geodetic Configuration as Project Coordinate System.
2nd Datum ( Name )
Height value will be on the selected Source Coordinate System in the Geodetic Configuration, e.g. 'WGS 84', 'ITRF2008' or 'ETRS89'.
Chart Datum ( Name ) - Default
Height value on the selected vertical datum, e.g 'NAP - De Min Geoide'.
Note that Chart Datum (or Vertical Datum) is set in the Geodetic configuration as Vertical Datum under the Project Coordinate System.
Actual Water Level
Height value above the actual water (or sea) level.
The following formula is used: Geoid Level + Tide + Swell
The swell is derived from the roll, pitch and heave of the reference node, and the offset of the selected node to the reference node.
The heave value of the reference node can be monitored under the heave column of the Height Aiding driver.
Mean Water Level
Height value above 'mean' water (or sea) level.
The following formula is used: Geoid Model + Level Model + Offset
Geoid Model Level
Height value above input geoid model. Only used in case of River Height Model.

Node SOG

The speed over ground for the node location of the ADCP sensor.

Notice that the SOG depends on the Controller's Computation Setup, Object COG/SOG - Prediction Parameters Settings.

double

Unit:

Meters/Second (default)
Knots
Nautical miles per hour
(1 NM equals 1852.0 meters)
Feet/Second
International feet per second
(1 foot equals 0.3048 meters)
Kilometers/Hour
Miles/Hour
International (or Land) miles per hour
(1 mile equals 1609.344 meters)

Node COG

The course over ground of the object on which the ADCP node is located.

Notice that the COG depends on the Controller's Computation Setup, Object COG/SOG - Prediction Parameters Settings.

double

Reference:

True
The COG value plus the grid convergence.
Grid (default)
The COG value as is.

Node Heading

The heading of the object on which the ADCP node is located.

If the object does not have a valid heading, then the (COG + Convergence) will be displayed.

double

Reference:

True
The Heading value as is.
Grid (default)
The Heading value minus the grid convergence.

Rotation:

Standard (default)
90-Hdg (Righthand rule)

Cell Number

The selected cell number.

integer

Cell Depth

The depth for the selected cell number.

double

Cell Velocity

One of the beam velocities for the selected cell number.

Use the Parameter property to select for which beam you want to see the velocity.

Further, the velocity value is a raw value, and its reference depends on the selected coordinate system.
