    • The present invention provides methods and systems that enable a mobile navigation receiver to accurately determine its trajectory with non-current ephemeris in stand-alone mode. In an embodiment, the receiver computes the position for the same location using non-current ephemeris and current ephemeris at different time instances. The receiver then determines a position correction by finding the difference between these two computed positions, and applies this correction to the trajectory generated with non-current ephemeris to obtain a more accurate trajectory. In another embodiment, the receiver computes an initial position of the receiver using non-current ephemeris and finds the difference between the computed initial position and an accurate approximation of the initial position. The receiver then shifts the subsequent receiver trajectory computed using non-current ephemeris by the difference to obtain a more accurate trajectory.
    • 本发明提供使移动导航接收机能够以独立模式的非当前星历精确地确定其轨迹的方法和系统。 在一个实施例中,接收机使用不同时间的非当前星历和当前星历表计算相同位置的位置。 然后,接收机通过找到这两个计算位置之间的差异来确定位置校正,并将该校正应用于由非当前星历产生的轨迹,以获得更准确的轨迹。 在另一个实施例中,接收机使用非当前星历表计算接收机的初始位置,并且找出所计算的初始位置与初始位置的精确近似之间的差。 然后,接收器将使用非当前星历计算的后续接收器轨迹移动该差,以获得更准确的轨迹。

    • The present invention provides methods and systems for keeping the ephemeris in a navigational receiver current to achieve fast TTFF without the need for connecting to an aiding network or remote server. In an embodiment, the receiver keeps the ephemeris current by downloading the ephemeris in the background. In the preferred embodiment, the receiver uses a background sleep/wake up process to download current ephemeris with minimal power drain. In this embodiment, the receiver alternates between a sleep mode and a wake up mode. During the wake up mode, the receiver attempts to download current ephemeris. The receiver then goes back to the sleep mode until the next wake up to conserve power. The receiver may wake up from the sleep mode to download the ephemeris when the stored ephemeris is no longer current or the ephemeris broadcasted from a satellite has been updated or based on receiver usage patterns.
    • 本发明提供了用于将星历保持在导航接收机当中以在不需要连接到辅助网络或远程服务器的情况下实现快速TTFF的方法和系统。 在一个实施例中,接收器通过在背景中下载星历来保持星历当前的状态。 在优选实施例中,接收机使用背景睡眠/唤醒过程以最小的功率耗散来下载当前星历。 在该实施例中,接收器在睡眠模式和唤醒模式之间交替显示。 在唤醒模式下,接收端尝试下载当前星历。 接收器然后回到睡眠模式,直到下一次唤醒以节省电量。 当存储的星历不再是当前的或者从卫星广播的星历表已被更新或基于接收机使用模式时,接收机可以从休眠模式唤醒以下载星历。
