A method for supporting determining the position of a plurality of nodes in a radio communication network , wherein the communication network is an ultra-wideband communication network, and wherein the communication network comprises a localization system that includes a processing unit, a primary anchor and at least one secondary anchor , the method comprising: the primary anchor transmits a poll message to the nodes and to the secondary anchor ; the primary anchor receives a response message from the nodes ; the secondary anchor receives said poll message from the primary anchor and said response message from the nodes ; the processing unit calculates the position of the nodes using position information and timing information, wherein said position information is position information of the primary anchor and of the secondary anchor , wherein said timing information is timing information of the poll message transmission by the primary anchor , of the poll message reception by the nodes and the secondary anchor , of the response message transmission by the nodes , and of the response message reception by the primary anchor and the secondary anchor , and wherein the timing information is transmitted to the processing unit through said communication network or through a further communication network; characterized in that the method further comprises selecting, by the localization system, an additional primary anchor if at least one of said nodes has not received the poll message, wherein the additional primary anchor transmits a further poll message to the nodes and to the secondary anchor , wherein the nodes transmit response messages to the poll message and to the further poll message, and wherein said response messages are transmitted in a predetermined order, wherein said predetermined order is a preconfigured order or wherein data indicative of said predetermined order is communicated to the nodes through the further communication network. the primary anchor transmits a poll message to the nodes and to the secondary anchor ; the primary anchor receives a response message from the nodes ; the secondary anchor receives said poll message from the primary anchor and said response message from the nodes ; the processing unit calculates the position of the nodes using position information and timing information, wherein said position information is position information of the primary anchor and of the secondary anchor , wherein said timing information is timing information of the poll message transmission by the primary anchor , of the poll message reception by the nodes and the secondary anchor , of the response message transmission by the nodes , and of the response message reception by the primary anchor and the secondary anchor , and wherein the timing information is transmitted to the processing unit through said communication network or through a further communication network; characterized in that the method further comprises selecting, by the localization system, an additional primary anchor if at least one of said nodes has not received the poll message, wherein the additional primary anchor transmits a further poll message to the nodes and to the secondary anchor , wherein the nodes transmit response messages to the poll message and to the further poll message, and wherein said response messages are transmitted in a predetermined order, wherein said predetermined order is a preconfigured order or wherein data indicative of said predetermined order is communicated to the nodes through the further communication network. <EOS>
