摘要： A short range radiolocation system and associated methods that allow the location of an item, such as equipment, containers, pallets, vehicles, or personnel, within a defined area. A small, battery powered, self-contained tag is provided to an item to be located. The tag includes a spread-spectrum transmitter that transmits a spread-spectrum code and identification information. A plurality of receivers positioned about the area receive signals from a transmitting tag. The position of the tag, and hence the item, is located by triangulation. The system employs three different ranging techniques for providing coarse, intermediate, and fine spatial position resolution. Coarse positioning information is provided by use of direct-sequence code phase transmitted as a spread-spectrum signal. Intermediate positioning information is provided by the use of a difference signal transmitted with the direct-sequence spread-spectrum code. Fine positioning information is provided by use of carrier phase measurements. An algorithm is employed to combine the three data sets to provide accurate location measurements.

摘要： Systems and methods are described for determining positions of indoor localization beacons without requiring a physical site survey. In a coarse positioning method, a mobile node receives beacon signals that identify rooms (such as stores in a shopping mall) in which the beacons are located. The mobile node obtains floor plan information relating to the building and estimates beacon locations based on the floor plan and beacon signal strength. The estimated beacon locations may be arranged in a predetermined geometric pattern based on the number of beacons in a room. In a fine positioning method, a mobile node recognizes its proximity to a beacon and responsively measures the distance to other beacons. Estimated beacon positions may be used to estimate the location of the mobile node using trilateration or other techniques.
摘要翻译：描述了用于确定室内定位信标的位置而不需要物理位置调查的系统和方法。在粗定位方法中，移动节点接收标识信标所在的房间（例如商场中的商店）的信标信号。移动节点基于楼层平面图和信标信号强度获得与建筑物相关的平面图信息并估计信标位置。估计的信标位置可以基于房间中的信标的数量以预定的几何图案来布置。在精细定位方法中，移动节点识别其与信标的接近度并且响应地测量到其他信标的距离。可以使用估计的信标位置来使用三边测量或其他技术来估计移动节点的位置。

摘要： It is proposed to provide a system for localizing a vehicle in a marked environment, provided with a set of markers, e.g. on a road side, the markers emitting a position signal indicative of a respective marker's known geographical position. The system comprises a distance detection unit and a processing unit provided in the vehicle, the processing unit adapted to receive said position signal of a respective marker. The processing unit is adapted to receive said known geographical position from the position signal of said respective marker; and to estimate a first distance measure of the vehicle relative to the respective marker based on a position signal measurement. The processing unit feeds said estimated first distance measure to the distance detection unit; the distance detection unit being adapted to detect said marker within the first distance measure by a second distance measure. The distance detection unit is further adapted to provide the processing unit with the second distance measure of the vehicle relative to the detected marker and with a detection angle of the detected marker; and the localization unit calculating an instantaneous geographical position of said vehicle from the second distance measure; the detection angle and the marker's known geographical position.

摘要： A mobile device can be in multiple states of location determination. In each state, the mobile device can use a distinct subsystem to determine a location. A state machine of the mobile device can manage the states, including determining which state the mobile device is in and whether a transition between the states has occurred. A transition can be triggered by a sensor of the mobile device and confirmed by another sensor of the mobile device. When the state machine detects a transition, the mobile device can switch location determination from one subsystem to another subsystem, and change a map user interface to one that is best suited for the new subsystem.
