摘要： Methods and apparatuses for a mobile station to obtain a position fix using synchronous hybrid positioning and asynchronous hybrid positioning techniques are described. In one embodiment, a wireless communication apparatus may transmit a request to a mobile station for timing reference information. The apparatus may be configured to receive the timing reference information, first timing measurements from a first positioning technology, and second timing measurements from a second positioning technology. The apparatus may identify whether the mobile station is capable of supporting synchronous hybrid positioning based on the timing reference information. If it is synchronous hybrid capable, then the apparatus may then establish a position fix for the mobile station using a synchronous hybrid positioning technique that involves relating the first and second timing measurements to a common time scale based on the timing reference information. If it is not synchronous hybrid capable, then the apparatus may establish a position fix for the mobile station using an asynchronous hybrid positioning technique wherein the time scales of the first and second timing measurements are not interrelated.

摘要： Embodiments of an improved assisted global positioning system (GPS) method and system are described. Wireless access points send assistance data to GPS receivers that are integrated into cellular chipsets and other chipsets. The access points may also act as fixed location references for differential GPS (DGPS) mobile stations. Errors caused by multipath travel of the GPS signals are reduced by using fixed location reference receivers.

摘要： A navigation system is described which includes a mobile terminal 100 which has a transmission source receiver 204 for receiving the signals from one or more unsynchronised terrestrial transmission sources 102-105 and a satellite positioning receiver 200 for receiving signals from the satellite or satellites 107-110 of a satellite positioning system. The terminal also has a clock 208. A processor 209 is arranged to acquire a measurement vector having a list of values, each value representing a measurement made by a receiver 200,204, and the terminal clock's bias. It computes a state vector representing the current state of the system, using a previously-determined state vector, the measurement vector, and a dynamic model in order to derive a dynamic navigation solution. The elements of the state vector include (a) in one or more dimensions at least position information of the terminal 100; (b) representations of the bias of the clocks associated with the unsynchronised terrestrial transmission sources 102-105 relative to a given time; (c) the bias of the terminal clock 208; (d) quality indicators indicating the error associated with elements of (a) to (c); and (e) linking indicators indicating the dependency of elements in (a) to (c) on others of those elements.
