Abstract:
This study develops a drone positioning system for use in indoor environments, including dark places, inaccessible areas, and ordinary living environments that do not accommodate conventional methods. Various indoor drone applications have been developed, such as drone communication systems and wall surface inspection, which require remote estimation of drone position. For outdoor applications, a Global Navigation Satellite System (GNSS) is generally used to obtain the drone position. However, as the GNSS radio waves cannot reach indoors or between buildings, camera-based methods, such as Simultaneous Localization and Mapping (SLAM), are applied to estimate the drone’s position. The system uses noise-resistant, code-division-multiplexed spread spectrum (SS) ultrasonic waves for three-dimensional positioning. Transmitter and receiver hardware is developed using SS ultrasonic waves and the effect of wind and sound of the positioning system during drone operations on the SS ultrasonic positioning is evaluated. Transmitter and receiver hardware is developed using SS ultrasonic waves and the effect of wind and the sound of the positioning system during drone operations on the SS ultrasonic positioning is evaluated. The accuracy of the positioning system is verified through experiments, and the results indicate that a positioning accuracy within 15 cm is possible despite the effects of downwash generated by the drone’s wings, and there was no effect of multipath on the positioning error.
