Abstract

Due to the limited load capacity of small unmanned aerial vehicles (UAVs), micro pressure sensors are generally selected to measure altitude and airspeed. However, micro pressure sensors have relatively large absolute error for altitude measurement when UAVs take off or land. Therefore, in this paper, an ultrasonic module is added to make up for the lack of altitude measurement when UAVs take off or land (altitude is below 10 m). This paper mainly introduced the principle of ultrasonic ranging and tested the validity of ultrasonic ranging data. The test results showed that for some complex situations, ultrasonic ranging data needs to be filtered, and it also showed that Kalman filtering could meet the requirements of unmanned ultrasonic low altitude measurement. Finally, this paper proposed the basic architecture of the UAV height fixing control system in combination with ultrasonic ranging technology.
