Antenna Off-Set
 Displays the appropriate bias adjustment values for the antenna model in use (optional).

 Phase Center Adjustment (H1): The offset in millimeters from the physical center of the
antenna (the element) to the Mechanical Reference Plane (MRP). The MRP is at the bottom
of the BSW antenna mount. The range limits are -128 to 127mm.
 Radius of Antenna Body: The measurement in millimeters from the physical center of the
antenna to the edge of the antenna. For a pole, enter 0. For a tripod, the range limits are -
32768 to 32767mm.
 Slant Range of Antenna Body: For a pole, the vertical measurement in millimeters from the
Mechanical Reference Plane (MRP) to the control point. For a tripod, the measurement in
millimeters from the edge of the antenna to the control point. The range limits are -32768 to
32767mm.
 Height Adjustment: Indicates whether or not the antenna offset is applied

A label on the bottom of NavCom supplied antennae provides the appropriate measurements
for the antenna in use.
Antenna Calibration Values are available from the National Geodetic
Survey (ngs.noaa.gov) site calibration table hyperlinked to this text.
Solid Earth Tide
Positions with Solid Earth Tide (SET) provide better vertical (primarily) and horizontal
positioning accuracy, to account for gravitational effects placed on terrain from celestial bodies
(i.e. the Sun, Moon, etc.). SET corrections are applied to the reported position only in StarFire
navigation mode.
