摘要：
A method of determining a position of a target device includes: sending a first measurement signal from a first known-position device; receiving the first measurement signal at a second known-position device; receiving a first acknowledgement signal from the target device at the first known-position device and at the second known-position device; determining the position of the target device using first timing information associated with the first measurement signal and the first acknowledgement signal, a first position of the first known-position device, and a second position of the second known-position device.
