16 Sets of Angles
Introduction Sets of Angles is used to measure directions to targets for which
coordinates are not necessarily known. Distance measurements
are optional.
The average direction of all sets, the standard deviation for the one
observed direction and the standard deviation for the average of all
directions is computed for each target.
This provides field checking and analysis of measurements while
the instrument remains setup on the station.
With motorized instruments rough pointing to each station is
automatic, the operator needs only to refine the pointing before
measuring. This eliminates observations to incorrect targets.
With Automatic Target Recognition, fine pointing and measurement
can be automatic when the target is a reflector. The operator
makes only the first observation to each station, then the rest of the
measurements can be fully automated.
