Abstract

A local positioning system for determining the position of mobile units, such terminals mounted on shopping carts in a store, comprising a base unit, a number of position-signal transmission units and at least one mobile unit. The base unit has transmitter means for emission of an activation signal to the position-signal transmission units and to the mobile unit. In addition, the position-signal transmission units have receiver means for reception of the activation signal and means for emission of a sound signal to the mobile unit in response to the activation signal. The mobile units have means for reception of said activation signal and sound signal, respectively, and processing means for determining the time differential between reception of the activation signal and the sound signal and for calculating the position relative to the position-signal transmission unit based on said time differential.
