摘要： The invention relates to a method for continuously locating in real time at least one mobile object which is placed in a multidimensional defined space. In order to carry out the inventive method, at least one mobile modularised transmitter is arranged on at least one mobile object whose signals are received and centrally processed by a fixed network for receiving and processing said signals. The signals emitted by the modularised transmitter are embodied in the form of electromagnetic waves emitted in a frequency range by a time-division multiplexing method. The invention is characterised in that the frequency range is used in the form of a single channel for maximising the accuracy of location and that the communication between the transmitters (Sp, Sb) and the receivers (E1, EN) is based on the principle of a time-division quasi-random multiplexing with bursts in the form of limited cross-correlations and non- synchronised quasi-random circuits. The inventive method makes it possible to obtain a very high local and time resolution of several milliseconds and continuously localise one or several mobile objects at any time and in any place. The inventive transmitters and receivers for carrying out said method are also disclosed.
