Abstract: System for measuring the distance between a central location and any number of remote locations. Two parallel beams of radiation emanate outwardly from the central location, and the beams are rotated at a known angular velocity. The time required for each of the two beams of radiation to sweep past a given point at a remote location is a function of the distance which separates the remote location from the central location, and that time can be determined at the remote location to indicate the separation distance. The beams of radiation may be parallel beams, or alternatively the beams may diverge at a known fixed angle that does not originate at the point of rotation.
