    • The present invention discloses a mobile positioning and tracking system that includes a master device and a slave device. Within a tracking range of the master device, a satellite is used for receiving a signal from the slave device, and then transmitting the signal to the master device to display an initial location of the slave device. Meanwhile, the master device compares the location of the master device with a relative direction, distance, height or angle of the location of the satellite signal received by the master device, such that the master device can search according to the relative location. If the slave device is situated within the tracking range of the master device, Zigbee is used for receiving a signal from the slave device to estimate the location of a target outside the tracking range, and accurately measure the relative location of the target within the tracking range.
    • 本发明公开了一种包括主设备和从设备的移动定位和跟踪系统。 在主设备的跟踪范围内,使用卫星接收来自从设备的信号,然后将信号发送到主设备以显示从设备的初始位置。 同时,主设备将主设备的位置与主设备接收的卫星信号的位置的相对方向,距离,高度或角度进行比较,使得主设备可以根据相对位置进行搜索。 如果从设备位于主设备的跟踪范围内,则Zigbee用于接收来自从设备的信号,以估计目标在跟踪范围之外的位置,并准确测量目标在跟踪范围内的相对位置 范围。
