Figure 69 Analog Format Settings
The options for Analog Format settings are:
<Disabled> Roll [rad]
Pitch [rad] Heave [m]
Mod.Roll [rad] sin(Mod.Roll) [-1 to 1]
sin(-Pitch) [-1 to 1] Constant
Heave Velocity [m/s] Roll, pure inertial [rad]
Pitch, pure inertial [rad] Mod.Roll, pure inertial [rad]
sin(Mod.Roll), pure inertial [-1 to 1] sin(-Pitch), pure inertial [-1 to 1]
other=0
In order to output Datawell Hippy or Piro compatible analog signals, the following variables,
gains and offsets must be selected:
Figure 70 Datawell Hippy compatible analog output signals
Note
Negative gain and the value 1 has to be used for "Heave" in order to make the
variables positive according to the Datawell co-ordinate system. The variable
"sin(Mod.Roll)"
is to be selected for roll and "sin(-Pitch)" for pitch. Both
variables to be selected with positive gain 10 in order to achieve analog Hippy roll
and pitch output.
Note
The pure inertial variables for roll and pitch are only recommended used for
vessels not cruising, such as dynamic positioned vessels that receive noisy or bad
GPS data. These roll and pitch angles are determined due to pure inertial
measurements and are not integrated with GPS.
