Auto Position 2D + Measure (TPS only)
Description
This auto position method 2D + Meas allows the instrument to aim at a 2D position. As the
natural surface height is unknown the correct position is calculated via iterations.
Workflow
The first position (b) the instrument points to is defined by the 2D coordinates (a) of the
point to stake out ( = horizontal direction) and the current vertical angle. Therefore, aim the
instrument at the approximate position of the point to stake out.
RoadRunner then compares the measured 2D position with the stake out position to determine a new position (c) to aim at. As no information about the natural surface is available,
RoadRunner calculates a point at the same height as the measured position. The new position (d) is measured and compared again with the point to stake out (a).
This iteration process runs until the tolerances defined for the stake out are reached.

a) 2D position to stake out
b) First position measured defined by 2D coordinates and current vertical angle
c) New position calculated based on height of b
d) Second position measured
e) New position calculated base on height of d.
The measured position for this point is within
the defined tolerance, the correct position is
found.
