Abstract:
This disclosure provides methods and systems for locating wireless mobile devices in an area, for example, using an unmanned aerial vehicle. An unmanned aerial vehicle may receive a wireless signal with identification information from a mobile device. The unmanned aerial vehicle may fly in wireless communication range with the mobile device; measuring, representative parameters related to the received wireless signal and associating the value of measured representative parameters with the mobile device identification and with the location of the unmanned aerial vehicle at the time the wireless signal was received and estimating, the location of the mobile device in the area based on the value of measured representative parameters and the location of the unmanned aerial vehicle at the time it received the wireless signal. The measurement of the representative parameters may be time-stamped and the location of the unmanned aerial vehicle at the time the wireless signal was received may be calculated based on the time stamp and flight information of the unmanned aerial vehicle.

Claim (Index 14):
The method of  claim 1  for locating mobile devices in an area, wherein the transmitted wireless signals further comprise bursts transmitted at short and long intervals, wherein the long interval is significantly longer than the short interval; and\n wherein the representative parameter related to the wireless signal is the Time of Arrival (TOA) of each burst of the wireless signal; and wherein \n the associated measured values are the Time of Arrival values associated with the respective location of the first unmanned aerial vehicle at the plurality of locations and at the time each burst of the wireless signal was received; and \n calculating the time offset between the mobile device clock and the first unmanned aerial vehicle clock based on the measured TOA of wireless signal bursts received at short intervals; and \n calculating the TDOA of wireless signal bursts based on the measured TOA of wireless signal bursts received at long intervals and the estimated clock offset; and wherein \n estimating, the location of the mobile device in the area further comprises estimating the location based on the calculated TDOA values and the respective locations of the first unmanned aerial vehicle at the plurality of locations and at the time it received the wireless signal bursts.
