1. A method of operating a position network center comprising at least one server, the method comprising:

  • receiving, at the position network center, timing-error data corresponding to a plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters, from at least one position network receiver; and

    transmitting, from the position network center, data that indicates a plurality of timing errors by the plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters and corresponds to a lack of synchronization between different networks, to a wireless user device that receives signals from the plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters, after receiving the timing-error data from the at least one position network receiver at the position network center.
