Parent Item

System:

List with all available 'observation' systems that exist in the currently selected Qinsy database.
(See General Layout Information about loading a Qinsy database.)
The following 'observation' systems are supported:

Gyro Compass
Underwater Sensor
Speed Log
Tide Gauge
Surface Navigation Systems
Magnetometer
Miscellaneous Systems
Dredging Sensor
Rotation Angle Sensor
Acceleration Velocity Sensor

Computed Height object name
Computed Attitude object name

Note that the last two systems are special ones and are always present for each available object.
They offer so-called 'pseudo' observations like the Computed Heading/Roll/Pitch/Heave, the RTK Tide and the AWL Draft observation.

These 'Computed' observations are not available when layout is for Export.

Observation:

List with all observations that are connected to the selected system above.

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.

System Name

Name of the selected system, as defined in Database Setup.

Name

Name of the selected observation, as defined in Database Setup.

Time

Time of the last raw update of the observation.

time

Value

Value of the last raw update of the observation.

Same value as seen in Observation Physics Display.

double

Apply C-O:

No
Raw value
Yes
The observation value will be corrected with the Fixed C-O, the Variable C-O, the Scale factor and the Squared term factor, as entered in Database Setup.
The following formula is used:
- Apply (C-O) offsets first:
  Corrected Value = (Squared term factor * Raw Value * Raw Value) + Scale factor * (Raw Value + Fixed C-O + Variable C-O)
- Apply scale factor first:
  Corrected Value = (Squared term factor * Raw Value * Raw Value) + Scale factor * Raw Value + Fixed C-O + Variable C-O

Age

The difference between the triggering time and the time of the last raw update (see above).
Normally always a positive value 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

Quality

Same quality as seen in Observation Physics Display.

Parameter

Additional system setup parameter.
Use item property Parameter to select which value you want to display or export.

Fixed C-O

Slot

Slot 1 Id of the selected observation, as defined in Database Setup.
Will be empty if no slot has been defined for the observation, or if the observation does not support slot id's.
