Precision 9 Software Update
- Precision-9 now offers continual automatic calibration. The Precision-9 continuously gathers new calibration data and compares it with the current stored calibration, if the new calibration data exceeds a certain performance threshold, the new data will be used.
- Precision-9 now offers standard NMEA2000 Heave PGN127252.
Precision-9 Heave output will be utilized by other Simrad products in future software releases.
Technical Details for Compass Calibration
For Precision-9, there are two sets of calibration parameters at all times. Those are the user calibration parameters, and the auto calibration parameters which is introduced by this feature. To control which is used, a set of modes for the auto calibration is available for the user with a Navico MFD.
The different modes are:
- Auto calibration off
- Auto calibration on
- Auto calibration locked
- Auto calibration auto
Auto calibration off:
The compass uses the available user calibration parameters in the calculation of the heading. The auto calibrator still gathers data and calculates new auto calibration parameters. These parameters cannot be put to action until another mode is selected. The result will be a new 20-minute phasing of the parameters.
Auto calibration on:
The standard auto calibration mode. At all times new data is gathered and continuously compared to the current auto calibration parameters in use. New parameters are only applied when the performance level is over a certain threshold.
Auto calibration locked:
The mode where the auto calibration parameters are not changed.
When the user is satisfied with the performance of the compass heading, they can put the auto calibration mode to auto locked. Still, data is gathered and the data is always compared to the current calibration parameters to update status and warning, but the parameters will never be changed.
