    • A system and method for determining a position of a wireless mobile device. The method comprising the steps of providing one base station in communication with the mobile device, providing a sensor spaced apart a known distance from the base station, and determining the range between the mobile device and the base station. The time of arrival of a signal transmitted from the mobile device is measured at the sensor and a set of coordinates is calculated for the mobile device relative to the sensor as a function of the known distance from the sensor to the base station, the range between the mobile device and the base station, an estimate of base station transmission timing relative to a time source, and the time of arrival. One of the set of coordinates may then be chosen to thereby determine a position of the mobile device relative to the sensor.
    • 一种用于确定无线移动设备的位置的系统和方法。 该方法包括以下步骤:提供与移动设备通信的一个基站,提供与基站间隔开已知距离的传感器,以及确定移动设备与基站之间的距离。 在传感器处测量从移动设备发送的信号的到达时间,并且针对移动设备相对于传感器计算一组坐标作为从传感器到基站的已知距离的函数, 移动设备和基站,相对于时间源的基站传输定时的估计以及到达时间。 然后可以选择坐标系中的一个,从而确定移动设备相对于传感器的位置。
