Stability of the prism setup
The demands made on the stability of the prism when
measuring several sets of angles for monitoring a dam
are different from the demands in connection with a
topographic survey. In the first case, better accuracies
are expected.
In accordance with the distance-measuring program
selected, a tolerance range is defined within which the
prism may apparently or actually move.
Tolerance range for prism stability
In the first stage, the Automatic Target Recognition
ATR1 investigates the stability of the prism. If this is
acceptable, the angle corrections are then determined.
The accuracy of the measurement is always the same,
irrespective of the setting chosen.
