摘要:
The invention relates to a system for determining the position of an object, comprising a reference transmitter device (202) disposed in a fixed position. Said reference transmitter device (202) is provided with a reference time supplying unit for supplying a reference time signal that indicates a reference time. The system further comprises at least two transmitter/receiver devices (302) that are disposed in fixed positions with respect to each other and to the reference transmitter device (202). Every transmitter/receiver device (302) is provided with a time-supplying unit for supplying a time signal that indicates a time, a receiver for receiving the reference time signal from the reference transmitter device (202) and a synchronization device for processing the time signal and the reference time signal and for synchronizing the time with the reference time. A positioning device (502) on the object determines the position of the object.

An oval ball, in particular a rugby ball or football having a shell and at least one electronic component or module, which is arranged inside the shell, is held in a predetermined position, and has a transmitter, wherein the at least one electronic module is attached in a form-fitting and/or bonded manner to or in a molded part in the area of the tip or in the area of a valve of the shell. In another embodiment, the module is suspended on nets attached at the tip area of the shell over a large area.

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.
