摘要： Aspects of the disclosure provide an apparatus that includes a navigation signal receiver and a processing circuit. The navigation signal receiver is to receive, from a plurality of satellites, first ephemeris data. The first ephemeris data is effective for a first time duration. The processing circuit is to predict, based on the first ephemeris data, second ephemeris data. The second ephemeris data is effective for a second time duration that is extended beyond the first time duration. The second ephemeris data is used by the navigation signal receiver to acquire satellite signals for positioning the apparatus during the second time duration.
