Vector Configuration

Use this page to set heading and attitude parameters for the heading vector.

Select Receiver Configuration / Vector.

 

Heading

• Heading Adjustment – Heading adjustment in degrees.

• Direction – Set the direction of the internal vector for heading, either Normal (from the Vector antenna to the Position antenna) or Reversed (from the Position antenna to the Vector antenna).

• Apply adjustment to – Select if the adjustment is to be applied to all heading outputs or only to heading from true north (see NMEA HDT.)

Attitude

• Slope Adjustment – Enter the slope adjustment, in degrees, manually. Alternatively, if one of the calibration options is selected, it will be automatically calculated.

• Calibration Options – When enabled, you can calibrate the vector by calculating the slope adjustment based on one of the following criteria:

  • from Raw Slope – When you click Recalculate, the current slope angle is set to zero.

  • from Antenna Delta Height – Enter the delta height in meters from the antenna phase center (APC) of the Position (POS) antenna to the APC of the Vector (VECT) antenna. For example, if the POS antenna is higher than the VECT antenna, use a negative delta height to adjust the slope to zero.

• Recalculate – Click Recalculate to perform an instant recalculation of the slope adjustment. This is useful if you are using the from Raw Slope calibration method on a moving vessel. Note that the receiver position solution type must be at least as good as the Minimum Solution Type defined to be able to use the Recalculate function.

• Direction – Set the direction of the internal vector for the slope, either Normal (from the Vector antenna to the Position antenna) or Reversed (from the Position antenna to the Vector antenna).

• Orientation – Set to either Pitch or Roll depending on the orientation of the antenna baseline with respect to the vessel centerline. This setting is also used to determine which field is populated in Attitude output messages such as the NMEA AVR.

• Minimum Solution Type – Set this to determine the precision of the Vector solution. For the highest precision, set it to RTK Fixed. For best productivity, set it to RTK Float. On the receiver, it shows what solution type the receiver is receiving, not what you have set it to here.
