Ultrasonic Positioning

Ultrasonic positioning uses high-frequency sound waves (above human hearing) to determine the location of objects or devices. A system includes transmitters that send ultrasonic signals and receivers that detect them. By measuring how long it takes for the signals to travel between the transmitter and receiver, the system calculates distances. Multiple measurements allow precise calculation of an object's position in space. This technology is often used in robotics, indoor navigation, and asset tracking because it provides accurate and real-time location data without relying on GPS, especially in environments where GPS signals can't reach.
