point 0017, you get too close to the building causing the Kinematic SV Alarm to
sound, indicating loss of initialization. You must re-initialize. You return to the
initializer bar. If you were careful not to move (rotate) the bar, you can treat the bar
point as a known point and perform a Known Point initialization. The bar point is
considered known because you successfully positioned it when you performed
your Bar Point initialization. During processing, the coordinates of the bar point
will be determined prior to your subsequent loss of initialization. But, this is only
true if you were careful not to rotate the bar. If the bar moved, the position at the
end of the bar is no longer known. In this case, you must perform a Bar Point
initialization once again.
• In this third scenario, you are in the middle of performing a kinematic survey
which you initialized in any available manner (it is not important which method
was used). You have now successfully established 172 new points. You are about
to attempt to observe some points in an area where there are some trees. You
suspect that you may lose initialization while attempting to get close to the trees.
You are not close to the kinematic base nor close to any known points. As a pre-
caution, you put a PK nail in the ground at your current location and observe it with
Stop-and-go, being sure to tag it as a Control point. This point is called 0173 and
now can be considered a known point. You move into the obstructed area and
successfully establish points 0174 - 0181. As you are moving to the next point, the
Kinematic SV Alarm sounds. You must re-initialize. Initialization can quickly be
accomplished by performing a Known Point initialization on point 0173.
Scenario number 3 above illustrates the benefit of establishing convenient
initialization points as you move about the project site. If you find that you have
moved a considerable distance from the kinematic base or a control point, quickly
set a new control point in your area for re-initialization. Do the same if you are
about to move into an area where initialization may be lost due to obstructions. By
following this procedure, you will always be close to a point that can be used for a
Known Point initialization.
