Abstract:

A mobile communication device () and peer mobile communication devices () are capable of direct voice and data communication. The mobile communication device has a reference oscillator () which is used for generating operating frequencies, and is subject to frequency errors resulting from manufacturing tolerances, heat, and other error sources. The mobile communication device receives a frequency correction message () from a peer mobile communication device that has calibrated its reference oscillator. The frequency correction message contain offset information which is used by the mobile communication device to determine its offset () from a nominal frequency ().

International Classification:

G01S 3/02

US Classification:

342464000, 342357150

Abstract:

A mobile device () includes a satellite positioning receiver () for determining a precise location of the device (). The first time the precise location is determined, the satellite positioning receiver is provided with location aiding information including an approximate location and a radius of uncertainty. The approximate location is determined by acquiring the location of a present base station (), and the locations of one or more neighbor base stations (), and calculating the spatial center of the base stations, and adjusting the spatial center according to received signal strengths of the base stations. A radius around the approximate location is then determined. The approximate location and radius are provided to the satellite positioning receiver.
