Abstract
Methods of operating a position network center, which includes at least one server, may include receiving timing-error data corresponding to a plurality of unsynchronized or loosely synchronized transmitters from at least one position network receiver. Moreover, the methods may include transmitting data indicating a plurality of timing errors by the plurality of unsynchronized or loosely synchronized transmitters to a wireless user device that receives signals from the plurality of unsynchronized or loosely synchronized transmitters. Related position network centers, position network receivers, and wireless user devices are also described.
