A first transceiver ( 4, 30 ) can position itself by forming an ad hoc network ( 20 ) of transceivers which assist the first transceiver in acquiring its position. A dedicated infrastructure such as GPS satellites is not required. The first transceiver ( 4, 30 ), once it has acquired its position, can be involved in a network ( 20 ) by another transceiver ( 32, 34, 36, 38, 40 ) to assist in the positioning of that transceiver. The acquisition of the position may involve factors such as the trustworthiness of the transceivers in the network and/or the positions of transceivers with which the first transceiver cannot directly communicate.
