PROBLEM TO BE SOLVED: To provide a receiver system for positioning, a method for arranging the receiver system and a positioning system provided with the receiver system.SOLUTION: The receiver system has a node group consisting of reception nodes to receive a range finding signal. The reception nodes in the node group are arranged in a prescribed form. The node group has a reference node and positions of reception nodes other than the reference node in the node group are decided based on information on the prescribed form as well as the position of the reference node. The receiver system has a more flexible configuration than a conventional system in terms of high compatibility with a complicated situation to be encountered in a practical use. At the same time, the receiver system can significantly reduce a work load required for calibration in the complicated application situation.
