A set of base stations (121,122,123,124) and a central control unit (110) are arranged to determine the positions of animal tags (T) based on triangulation and using a global time reference (CLK) andrespective radio tag signals (ST) transmitted from each animal tag (T). Moreover, each of the base stations (121,122,123,124) is configured to transmit a respective radio base signal (SB1) comprisingan identifier that uniquely identifies the base station (121), receive radio base signals from the other base stations, and forward base station messages (MB1(t2), MB(t3), MB(U)) received from any other base stations to the central control unit (110). The central control unit (110) is further configured to determine a position (P[B1]) for any added base station (121) using triangulation and the known positions for the base stations (122,123,124) already included in the system. Thereby, the base station system can be gradually expanded in a very convenient manner. 一组基站(121、122、123、124)和中央控制单元(110)被布置为基于三角测量并使用全局时间参考(CLK
