    • Techniques for accurate position location and tracking suitable for a wide range of facilities in variable environments are disclosed. In one aspect, a system for position location comprises a plurality of sensors (e.g. a network monitor, an environment sensor) for generating a measurements of a plurality of sources, a plurality of objects or tags, each object generating measurements of the plurality of sources, and a processor for receiving the measurements and generating a position location for one or more objects in accordance with the received measurements. In another aspect, a position engine comprises a mapped space of a physical environment, and a processor for updating the mapped space in response to received measurements. The position engine may receive second measurements from an object within the physical environment, and generate a position location estimate for the object from the received second measurements and the mapped space. Various other aspects are also presented.
    • 公开了用于在可变环境中适用于广泛设施的精确位置定位和跟踪的技术。 在一个方面,一种用于位置定位的系统包括用于产生多个源,多个对象或标签的测量的多个传感器(例如,网络监视器,环境传感器),每个对象产生多个源的测量 以及处理器,用于接收测量并根据所接收的测量值生成一个或多个对象的位置位置。 在另一方面,位置引擎包括物理环境的映射空间,以及用于响应于所接收的测量来更新映射空间的处理器。 位置引擎可以从物理环境内的对象接收第二测量,并从接收到的第二测量和映射空间生成对象的位置位置估计。 还提出了各种其他方面。
