Method for the continuous real time tracking of the position of at least on mobile object as well as an associated device
First Claim
1. A method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, comprising at least one mobile transmitter module which is attached to at least one mobile object of the system that is to be analyzed and whose signals are received by a stationary receiving and signal processing network and are processed centrally, wherein the signals emitted by the at least one transmitter module are electromagnetic waves which are transmitted within a frequency band range utilizing a time division multiplex technique, characterized in that the available frequency band is used as a single channel for the purposes of maximizing the accuracy of the position detecting process, and in that the communication process between the transmitters (S, Sp, Sb) and the receivers (E1, . . . , En) is based on the principle of pseudo-random time division multiplex using non synchronized pseudo-random patterns, and in that the transmission signals in the different burst transmissions (B) are characterized by a low cross correlation.

Abstract
A method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space comprising at least one mobile transmitter module which is attached to at least one mobile object, the signals from said module being received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by the transmitter module are electromagnetic waves sent within a frequency band range using time division multiplex techniques. Due to the fact that the frequency band is used as a single channel for the purpose of maximizing the accuracy with which a position is detected, and due also to the fact that the communication process between the transmitters (Sp, Sb) and the receivers (E1, . . . , En) is based on the principle of pseudo-random time division multiplex using burst transmissions of low cross correlation with non synchronized pseudo-random patterns, there is created a method for the continuous tracking of the position of one or more mobile objects at any time and in any place which is of very high positional resolution and has a temporal resolution of just a few milliseconds.
