In a method of determining position information of a client device, reference devices include a master device and target devices. Target device clocks are synchronized with the master device clock based on one-way message information. For each of the target devices a first time correction is determined based on a two-way ranging message. A first message transmitted from / to the respective target device is timestamped by several target devices corrected for the first time correction. Position information of the client device is determined based on time-of-flight information of the first messages in which the first timestamp is corrected for the first time correction.
