Abstract: PROBLEM TO BE SOLVED: To provide a method for supporting a mobile station to find a position of a satellite by using an effective message format including extended SPS (satellite positioning system) orbit correction information.SOLUTION: A server calculates correction between rough orbit data of the satellite and accurate orbit data of the satellite. A coordinate system is selected so that a change of correction is sharply smoothed with time. The server further calculates the correction roughly by using a mathematical function in order to reduce the number of bits necessary for transmission to the mobile station. When receiving a coefficient, the mobile station evaluates the mathematical function by using the coefficient and application time (e.g. present time), converts the evaluated result into a standard coordinate system and applies the converted result to the rough orbit data to acquire the accurate orbit data.

Abstract: PROBLEM TO BE SOLVED: To reduce the frequency of necessary almanac and/or ephemeris download directly from a satellite or from a location assistance server. SOLUTION: A server computes correction between coarse orbit data of a satellite and precise orbit data of the satellite. A coordinate system is selected so that a variation of the correction is substantially smooth over a time. The server further approximates the correction with a mathematical function to reduce the number of bits necessary for transmission to a mobile station. Upon receiving the coefficients, the mobile station evaluates the mathematical function using coefficient 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.

Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting navigation beacon signals that enhance accuracy of position determination.SOLUTION: A plurality of navigation beacon signals 21, 22 and 23 are detected by using either two antennas 11 and 12 or a synthetic aperture antenna and combining a plurality of distinct measurements using a plurality of antenna weight components to form an interference cancellation beam. In one embodiment, the plurality of antenna weight components are determined by eigenvalue processing. In another embodiment, the plurality of antenna weight components are determined by simplified processing. In another aspect, a single antenna is used for receiving an originally received measurement. A copy of the originally received measurement is created and processed to achieve a proper time delay to emulate spatial diversity. The originally received measurement and the processed copy are combined to form an interference cancellation beam.

Abstract: 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.

Abstract: A method and device for combating cross-correlation false alarms by introducing code diversity in the correlation process in which the search code may be diversified by the use of code staggering and/or code scrambling. The energy levels of the signals before and after the search code have been diversified may be evaluated to detect a false alarm. In addition, a set of parameterized analytical models may be used to estimate the rate of false alarms from cross-correlation in wireless networks in order to guide development and design of wireless transceivers.
