Abstract
A system for measuring distances between a central location and any number of remote locations. A transmitter at the central location radiates one or two rotating beams which rotate at an angular velocity which need not be determined. Specially placed sensors at a remote location sense the passage of the beam or beams and allow the accurate determination of the distance between the transmitter and the sensors without the need to measure and/or communicate the angular velocity of rotation of the transmitter signals.
