| 20090264136 | SYSTEM AND/OR METHOD FOR REDUCING INITIAL POSITION UNCERTAINTY IN SPS OPERATION - The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark. | 10-22-2009 |
| 20090318167 | LOCATION SPECIFIC SEARCH FOR REGIONAL SATELLITE VEHICLES - A position location system, method, and apparatus are disclosed. A wireless device receives a first signal and obtains an identifier indicative of a first location from the first signal. The first signal can be received from a cellular base station and the first identifier can be a mobile country code. The wireless device uses the identifier to determine the availability of signals from a regional satellite system at the first location. If signals from the regional satellite system are available at the first location, the wireless device retrieves information associated with one or more satellite vehicles in the regional satellite system. The information can include pseudo-random number codes and a Doppler search range corresponding to the first location. The wireless device receives a second signal and processes the second signal to obtain first satellite signal information. The wireless device determines its position at least partially based on the first satellite signal information. | 12-24-2009 |
| 20100097494 | Multimode GPS-Enabled Camera - A method and device of geographically tagging images by capturing an image, determining a position based on detection of satellite signals and a wireless network signal, and tagging the image with the determined position is provided. | 04-22-2010 |

| 20100309044 | On Demand Positioning - The subject matter disclosed herein relates to determining a location of a mobile device using more than one location-determining technology. | 12-09-2010 |
| 20100309057 | Mobile-Based Positioning With Non-Conforming Use Of Assistance Data - Apparatus and methods for performing mobile-based positioning in a wireless communications system are presented. A position estimate is computed based on assistance data intended for a first position method. The mobile device ignores if a second positioning method is not specifically supported by a network and computes a position estimate using the second position method and a subset of assistance data intended for the first positioning method, which is supported by the network and is different from the second positioning method. | 12-09-2010 |
| 20100331010 | Trajectory-Based Location Determination - The subject matter disclosed herein relates to determining a location of a mobile device using an estimated trajectory of motion of the mobile device, and in particular, using a comparison of the estimated trajectory with one or more predetermined candidate trajectories. | 12-30-2010 |
| 20110057836 | Position Estimation Assistance Information For Mobile Station - The subject matter disclosed herein relates to providing assistance information to a mobile station for performing position estimation operations. | 03-10-2011 |
| 20110084876 | QUALIFYING COARSE POSITION INJECTION IN POSITION DETERMINATION SYSTEMS - A position determining system (PDS) receiver gathers independent location information from multiple sources. These multiple pieces of location information are analyzed to determine consistency of location. If the location is consistent among the various independently gathered location information, then the location information is injected into the PDS positioning process for more efficient acquisition and positioning. Otherwise, if inconsistency is found, then no location information is injected into the PDS positioning process. | 04-14-2011 |
