Angle Offset is used to measure the points which are intervisible but hava no
reflector and can’t set up the prism. The basic principle is making the target point
and measurement point in the concentric circles whose center is station point, then
measuren the position information of station point and measurement point and the
angle offset of station to target point, thus can calculate the coordinate of target
point.
Set the measurement point P in the place where is as far as possible to close the
left or right of target point C, and make the distance between measurement point P
and station point A and the distance between station point A and target point C are
approximately equal.
