摘要：
A system for tracking a ground imaging apparatus includes a plurality of fixed devices and at least one tracked device. The fixed devices are positioned at fixed locations and the tracked device is affixable to the ground imaging apparatus. The fixed devices and the tracked device are configured to transmit and/or receive signals used for time of flight measurements. A processor is configured to determine one or more positions of the tracked device relative to one or more of the fixed devices based upon one or more time of flight measurements between the tracked device and one or more of the fixed devices.
