Abstract: A method and a system for vehicle head direction compensation are disclosed. The method includes the following. A relative position between each of a plurality of sensors disposed on a vehicle and a plurality of base stations is obtained through the sensors and a relative coordinate system is established by a processor to obtain a vehicle head direction of the vehicle in the relative coordinate system and a deviation angle between an X-axis of the relative coordinate system and a true north azimuth. An angle compensation is performed by the processor on the vehicle head direction of the vehicle in the relative coordinate system based on the deviation angle.

Abstract: A UAV (unmanned aerial vehicle) including a first barometer and a processing unit is provided. The first barometer provides a first air pressure value. The processing unit is coupled to the first barometer for receiving the first air pressure value from the first barometer, performing timing-synchronization on the first air pressure value provided by the first barometer and an external reference air pressure value provided by an external reference barometer to obtain a timing-synchronized first air pressure value and recalculating the timing-synchronized first air pressure value to generate a compensated air pressure value, wherein the processing unit performs data fusion calculation on the first air pressure value, the compensated air pressure value and a sensor data to obtain a target fused data and real-timely controls the altitude and the posture of the UAV according to the target fused data.

Abstract: An aerial vehicle including a body, a first ranging device, a second ranging device and a controller is provided. The first ranging device is disposed on the body and is configured to detect a first distance between the first ranging device and the reflector. The second ranging device is disposed on the body and is configured to detect a second distance between the second ranging device and the reflector. The controller is configured to obtain an included angle between a direction of the body and the reflector according to the first distance and the second distance.
