1. A method for setting up a localization system, the localization system comprising a multiplicity of stationary radio transmitters and a mobile radio transmitter, the multiplicity of stationary radio transmitters comprising mobile radio-enabled stationary radio transmitters, the mobile radio-enabled stationary radio transmitters each being configured for radio communication using a mobile radio technology, the method comprising:
determining, using an ultra-wideband radio technology, at least one relative location reference between the mobile radio transmitter and at least one of the stationary radio transmitters;
determining positions of the mobile radio-enabled stationary radio transmitters by:
performing a coarse localization to determine coarse positions, the coarse localization being performed using the mobile radio technology, and
then performing a fine localization to improve the coarse positions; and
determining a position of the mobile radio transmitter using at least one of the determined positions of the mobile-radio enabled stationary radio transmitters and the at least one relative location reference between the mobile radio transmitter and the at least one of the stationary radio transmitters.
