A device and method for positioning and controlling railway vehicles. The device includes fixed stations () including first elements for transmitting/receiving () signals and a central control station () to which the fixed stations () are connected. Each railway vehicle () includes second elements for transmitting/receiving () signals. The signals transmitted by the first and second transmitting/receiving elements () including an identifier specific to the transmitter and at least one message and consist in non-sinusoidal radio signals with very large bandwidth whose spectrum ranges between 1 and 10 GHz. Each railway vehicle () and each fixed station () include processing elements () for determining the identifier and the at least one message of each received signal. The central control station () sends command control instructions.

Device and method for positioning and controlling railway vehicles with ultra-large bandwidth

A testing device for measuring radiation, immunity and electromagnetic characteristics of an object to be tested ( ), includes a conductive structure ( ) enclosing a testing volume where the object can be placed, the structure being provided with an opening ( ) capable of being closed. The testing device further includes a set of internal conductors called septa ( ), at least two in number, each septum defining in the testing volume, by its configuration in the structure, an electromagnetic coupling with the object; at least a septum is arranged in such a way that its electromagnetic plane is separate and not parallel to the electromagnetic plane of at least another septum.
