    摘要： The present invention relates to a method for acquiring satellite signals. The method utilizes the predictability of the first two words of each sub-frame of the navigation message, by controlling the acquisition time of the intermediate frequency data and the PN code, acquiring corresponding intermediate frequency data and PN code from the acquisition time, processing the intermediate frequency data and the PN code to determine whether the satellite signal is acquired, during the acquisition processing and determination process, the navigation message peeling operation is performed using the predictability of the first two words of each sub-frame of the satellite navigation message and PN code, in this way, extending the time of coherent integration is achieved, and thereby improves the acquisition sensitivity.

    摘要： A device management system is comprised of a server-side proxy component and at least one back-end computer. The server-side proxy component is configured to receive ephemeris and almanac data from a source and information from at least one client describing the geographic location of the client. The server-side proxy component is configured to send the ephemeris and almanac data and the information from the client to a back-end computer. Responsive to receiving this data and information, the computer compiles it into GPS data relevant to the location of the client.

    摘要： A method of predicting the orbit of a satellite of a satellite positioning system, including: associating first and second types of satellites with first and second models of celestial mechanics forces, respectively; storing first ephemerides data of a satellite, associated to first time intervals and second ephemerides data associated to second time intervals. Further, the method comprises: calculating reference satellite positions based on the first ephemerides data; estimating first and second satellite positions in the first time intervals by using the second ephemerides data and the first and second forces models, respectively; determining first and second estimate errors by comparing the reference positions with the first and second positions, respectively; and detecting the type of satellite between the first and second types by an analysis of the first and second errors.

    摘要： A satellite radio signal receiver includes a receiving section and a processor. The receiving section receives a radio signal from a satellite and demodulates the signal to identify each received bit of the signal. The processor compares the identified received bit with estimated bits which are estimated to be received within a possible deviation range set for a current date and time acquired as a reception time of the received bit, so as to obtain information on comparison result in relation to a deviation from the current date and time. The processor detects the deviation which satisfies a predetermined match condition of comparison results for received bits. The processor acquires date and time information based on the detected deviation which satisfies the predetermined match condition.

    摘要： A method and apparatus for generating and distributing satellite tracking data to a remote receiver is disclosed. The method for includes extracting from satellite-tracking data initial model parameters representing a current orbit of at least one satellite-positioning-system satellite, computing an orbit model using the initial model parameters, wherein a duration of the orbit model is longer than a duration of the satellite-tracking data, comparing, for an overlapping period of time, the orbit model to the satellite-tracking data; and adjusting the orbit model to match the satellite tracking data for the overlapping period of time so as to form an adjusted orbit model. The adjusted orbit model comprises the long-term-satellite-tracking data.
