| 20090295630 | METHOD AND APPARATUS FOR POSITION DETERMINATION WITH EXTENDED SPS ORBIT INFORMATION - A method and system for assisting mobile stations to locate a satellite use an efficient messaging format. A server computes a correction between coarse orbit data of a satellite and precise orbit data of the satellite. A coordinate system is chosen such that variation of the correction is substantially smooth over time. The server further approximates the correction with mathematical functions to reduce the number of bits necessary for transmission to a mobile station. The mobile station, upon receiving the coefficients, evaluates the mathematical functions using the coefficients and a time of applicability (e.g., the current time), converts the evaluated result to a standard coordinate system, and applies the conversion result to the coarse orbit data to obtain the precise orbit data. | 12-03-2009 |
| 20100141470 | SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR REFRESHING DATA - A method performs an update for a first device that consumes information with a known expiration time. The first device operates within a network that accommodates other devices also consuming the information. The method includes setting a time for the first device to refresh the information, the time to refresh being based on a pseudorandom time offset. The method also includes sending a refresh request to a resource for the data during the set time. | 06-10-2010 |

| 20100194634 | METHOD AND APPARATUS FOR POSITION DETERMINATION WITH HYBRID SPS ORBIT DATA - A method and system for a mobile station to determine its position (or velocity) and time using a hybrid combination of satellite orbit data. In one aspect, the mobile station combines predicted orbit data from one satellite and real-time orbit data from another satellite in the determination of a fix. The combination can be made to the satellites in the same or different satellite systems. The mobile station can use the real-time orbit data of a satellite at one time period and the predicted orbit data of the same satellite at another time period. In another aspect, the mobile station can use the real-time orbit data to correct the clock bias in the predicted orbit data. The correction to the clock bias can be made to the same satellite that provides the real-time orbit data, or to a different satellite in the same or in another satellite system. | 08-05-2010 |

| 20100093377 | Creating And Using Base Station Almanac Information In A Wireless Communication System Having A Position Location Capability - In a wireless mobile communication system having a position determination service, base station information is stored in a base station almanac. In addition to the position of the base station antenna, forward link delay calibration, and base station identification information, a base station almanac record includes the center location of the base station sector coverage area, the maximum range of the base station antenna, the terrain average height over the sector coverage area, the terrain height standard deviation over the sector coverage area, round-trip delay (RTD) calibration information, repeater information, pseudo-random noise (PN) increments, uncertainty in the base station antenna position, uncertainty in the forward-link delay calibration, and uncertainty in the round-trip delay calibration. | 04-15-2010 |
