ABSTRACT:
Apparatus and methods are disclosed wherein the relative location of a point of position is mathematically determined based solely on knowledge of the included angles defined by an observation point and three non-colinear reference points, and of the distance between the three reference points. Apparatus and methods are also disclosed for position determining and position plotting which are not dependent on the existence of a predetermined or known relationship between the frames of reference defined for a chart, a plotter, and an external frame of reference for the positional data which is utilized to determine position.
