    • A task description is stored in a database accessible by a mobile computer system. The mobile computer system receives positioning information corresponding to its geographic location and indexes the database based on the positioning information when the information indicates that the mobile computer system is in a geographic location that facilitates completion of a task associated with the task description. The database may be resident in the mobile computer system or accessible in other ways, for example, via the Internet. The task description preferably includes a geocode which corresponds to the geographic location at which completion of the task may be facilitated. The task description may also include textual, voice or other message which can be displayed and/or played back to a user. The positioning information may be obtained from a GPS satellite, a GLONASS satellite or a pseudolite. The mobile computer system may be a portable unit, such as a PDA, or integrated within a vehicle.
    • 任务描述存储在移动计算机系统可访问的数据库中。 当信息指示移动计算机系统处于便于完成与任务描述相关联的任务的地理位置时,移动计算机系统接收与其地理位置相对应的定位信息,并且基于定位信息对数据库进行索引。 数据库可以驻留在移动计算机系统中,或者可以以其他方式访问,例如通过因特网。 任务描述优选地包括对应于可以促进完成任务的地理位置的地理编码。 任务描述还可以包括可以显示和/或播放给用户的文本,语音或其他消息。 定位信息可以从GPS卫星,GLONASS卫星或伪卫星获得。 移动计算机系统可以是诸如PDA的便携式单元,或者集成在车辆内。

    • A method for mobile navigation by using a smart phone is provided. The smart phone comprises: a GNSS navigation processor, a motion detector, a correlation processor, a triangulation processor, and a verified location display. The method of the present technology comprises: (A) obtaining a set of GNSS processor position fixes by using the GNSS navigation processor; (B) obtaining a set of motion-related data of the smart phone by using the motion detector; and (C) correlating the set of GNSS processor position fixes associated with the smart phone and the set of motion-related data associated with the smart phone and obtaining a set of GNSS correlation data. If the set of GNSS processor position fixes based on the set of GNSS correlation data is verified, the GNSS navigation processor is used for navigation; whereas if the set of GNSS processor position fixes based on the set of GNSS correlation data is not verified, the motion detector aided by triangulation processor is used for navigation.
    • 提供了一种通过使用智能手机进行移动导航的方法。 智能手机包括:GNSS导航处理器,运动检测器,相关处理器,三角测量处理器和经验证的位置显示。 本技术的方法包括:(A)通过使用GNSS导航处理器获得一组GNSS处理器位置定位; (B)使用运动检测器获取智能电话的一组运动相关数据; 以及(C)将与智能电话相关联的GNSS处理器位置固定集合与与智能电话相关联的一组运动相关数据相关联并获得一组GNSS相关数据。 如果验证了基于GNSS相关数据集的GNSS处理器位置集合,则使用GNSS导航处理器进行导航; 而如果没有验证基于GNSS相关数据集合的GNSS处理器位置集合的集合,则由三角测量处理器辅助的运动检测器用于导航。
