A Potentiometric Method for Transducing Large-Scale Position Using Tensioned Flexible Wires in Trilateration

Determination of position by triangular, rather than Cartesian, coordinates is outlined and formulated. The use of tensioned flexible wires to determine position is discussed from the theoretical and practical viewpoint. Details are given of an experimental Resiwire method, which achieved a precision of 1:18 000 and an accuracy of 1:4000 when determining position within an area 90 by 50 feet. Design equations and tables support the design of this potentiometric distance transducing method.
