An apparatus and method of determining relative position of a ground coil and a vehicle coil, enabling an electric vehicle to be guided to a position at which energy is transferable between the ground and vehicle coils. Position signaling devices are mountable relative to the ground and vehicle coils. At least one signaling device is associated with one of the coils and two or more signaling devices are associated with the other of the coils. Each signaling device is able to transmit or receive, or transmit and receive positioning signals for or from other ones of the signaling devices. The positioning signals are processed to obtain time-related information. The time-related information is obtained using at least two positioning protocols from a set of protocols. This enables determination of distances between the signaling devices and thus the relative position of the ground and vehicle coils.
