The pitch sensor records the rotational motion of the vessel around the X-axis (port/starboard). It is usually part of the MRU so it appears under the MRU component in the Vessels window.
The Pitch component has the following attributes in the Attributes window:
• Date: The year and Julian day of the pitch time stamp (see Component Time Stamps).
• Time: The hour and minute of the pitch time stamp (see Component Time Stamps).
• Time Correction: The time correction value.
• Error: The error in the pitch values recorded by the pitch sensor, measured in degrees.
HIPS and SIPS calculates the applied instantaneous pitch values by subtracting this error from the recorded pitch sensor values: Applied Pitch = Recorded Pitch - Pitch Error
• Apply: Select Yes to apply the pitch data in the Georeference Bathymetry process.
• Manufacturer: The maker of the pitch sensor equipment.
• Model: The particular make of the pitch sensor equipment.
• Serial Number: The serial number of the pitch sensor equipment.
• Comments: A text field for your use.
If the data is from a Kongsberg system and the vessel’s HIPS SVC Enabled property is False (see Vessel), then you must set Apply for Heave, Pitch, and Roll to No. This is necessary because Kongsberg systems apply dynamic heave, pitch, and roll values to the swath data during the data acquisition. If HIPS SVC Enabled is set to False for the vessel and Apply is set to Yes for Heave, Pitch, or Roll, then HIPS will apply both the Kongsberg and the HIPS corrections, resulting in incorrect data. |
