The station pointer allows an observer’s location to be plotted on a chart by measuring with a sextant the relative angles of three known objects (e.g. land features) from the observer’s position and setting the moveable arms to the observed angles. By placing the instrument on the chart and aligning the arms with the known objects, the centre of the circle indicates the observer’s position.
