摘要： 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.

摘要： Disclosed are methods, techniques and/or systems for selecting and/or determining a strategy and/or approach for searching for signals at a mobile device. Characteristics of and/or information obtained from such searched signals may be used in estimating a location of the mobile device. In one particular example, a strategy and/or approach for searching for wireless signals may be based, at least in part, on an availability of resources at a mobile device.
