Flight-control hardware steers the UAV along a flight trajectory that is determined by a ground-based UAV controller based at least on the radio transmission, such that the UAV or the ground station can locate or track the user equipment.

A execution status indication method includes receiving a control instruction sent from a control device, the control instruction being configured to instruct an unmanned aerial vehicle (UAV) to perform an operation; and controlling an indicator light at the UAV to indicate an execution status of the control instruction executed by the UAV.

The present application relates to an accelerator control method and device, a power system and an unmanned aerial vehicle (UAV). The method includes: receiving, by an electronic speed control (ESC), an accelerator signal through a serial communication interface; extracting accelerator control data from the accelerator signal; generating, according to the accelerator control data, a motor control signal for controlling operation of a motor; and transmitting the motor control signal to the motor. The accelerator signal received through the serial communication interface is a digital signal subjected to small interference during transmission, unlike an analog signal that is susceptible to interference such as impedance and capacitive reactance, which causes data inaccuracy. In addition, in the manner of serial communication, a higher baud rate may be adopted to shorten an accelerator control cycle, thereby achieving high-speed control of an accelerator and increasing the control frequency.
