Frequently Asked Questions

What is ultra short baseline?

Ultra Short Baseline (USBL) is a method used in underwater navigation to determine the position of subsea vehicles or divers. It involves a transceiver deployed from a surface vessel that sends acoustic signals to a transponder on the underwater target. The system calculates the position based on the time delays in signal reception using an array of hydrophones positioned very close to each other, typically within a meter. This technology is crucial for precise location tracking in subsea operations.

How does a USBL system work?

An Ultra-Short Baseline (USBL) positioning system operates by utilizing a transceiver mounted on a vessel’s hull to send acoustic signals to a transponder or responder on a subsea object. The system measures the time it takes for the signal to return and the angle of arrival relative to the transceiver’s built-in array of hydrophones. These measurements are then processed to calculate the position of the target relative to the vessel. This technology is essential for precise underwater navigation and positioning tasks

What is USBL calibration?

USBL (Ultra-Short Baseline) calibration is a process used to enhance the accuracy of USBL systems, which are used for underwater positioning and navigation. This calibration involves adjusting the system to account for variables such as sound velocity variations, positioning errors, and equipment misalignments. The process typically includes deploying a known reference target in the water, which helps in refining the system’s ability to accurately determine positions relative to the transceiver. Calibration is crucial for ensuring the reliability and precision of USBL systems in subsea operations.
