Abstract
A mobile computing device has a transceiver circuit, a location determination circuit, and a processing circuit. The transceiver circuit is configured to receive a remote position fix from a remote computer via a wireless network. The location determination circuit is configured to receive satellite data and to calculate a local position fix. The processing circuit is configured to operate an application, to receive a request for a position fix from the application, to determine whether the remote position fix is available, and to provide the local position fix to the application based on whether the remote position fix is available.
