Abstract
Methods and systems for position sensing are disclosed. In one embodiment, a method includes measuring at least three discrete point positions associated with a first component using at least one transmitter having a known position and orientation and in a line of sight with the three discrete point positions, the three discrete point positions having known distances relative to one another. The method computes a current position and orientation of the first component using data provided by the at least one transmitter and the three discrete point positions, along with position and orientation data from a last known location of the first component assuming that no sudden position changes since the first component has moved from the last known location. The first and second components may be a workpiece and a tool that performs a manufacturing operation on the workpiece.
