    Abstract: An unmanned aerial vehicle (UAV) control method includes generating a flight strategy for a target UAV in a UAV group, sending flight information to the target UAV, performing a clock synchronization on the target UAV to configure a reference time for the target UAV, and sending a take-off instruction to the target UAV. The flight strategy includes a flight instruction instructing the target UAV to fly to a target position at a target moment. The flight information includes the flight strategy. The take-off instruction triggers the target UAV to fly to the target position at the target moment according to the flight instruction by using the reference time as a standard reference time.
