An apparatus for determining a current position of a mobile device in an environment in which at least one transmitter is disposed includes a means for providing a cartographic map of the environment, the cartographic map including field strength reference values at reference points, a means for determining a field strength value, a means for deriving a reference point within reach that can be reached starting from a previous position of the mobile device by movement of the mobile device in the environment within a predetermined time interval, from the cartographic map of the environment, and a comparator for comparing the field strength value with a field strength reference value at the reference point within reach in order to determine the current position. By including the cartographic map of the environment, the position determination is simplified.

Apparatus and method for determining a current position of a mobile device

In a method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, at least one mobile transmitter module is attached to at least one mobile object and the signals from the at least one module are received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by each transmitter module are electromagnetic waves sent within a frequency band range using time division multiplexing 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 and the receivers is based on the principle of pseudo-random time division multiplexing 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.
