 Self Survey
This command performs a self survey
operation by averaging the GPS receiver’s position
over time and then applying that averaged position as the reference station position.
The receiver waits for a period of time (nominally 1400 minutes or 24 hours) to allow the
RTG readings to “settle.” This means there will be no valid survey results until this time
has passed. However, if the user specifies less than this value as the time limit, the
survey will continue until complete.
The user can set the duration of the survey in minutes then, click the Start button to begin
the survey, the Stop/Apply button to end the survey and the Cancel/Discard button to stop
the survey and eliminate any results.

After the self survey is completed, the user must save the current profile. If
the receiver reboots without saving the profile, the self survey position will be
lost.
 Antenna
Displays the appropriate bias adjustment values for the antenna model in use.
Figure 66: Antenna Height Adjustment Screen
 Height Adjustment: Indicates whether or not the antenna offset is applied.
 Phase Center Adjustment: 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.
 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
