Acoustic Navigation

Recent conflicts have exposed the vulnerability of Global Navigation Satellite Systems (GNSS) to electronic warfare, highlighting the importance of Inertial Navigation Systems (INS) for applications that demand Assured Position, Navigation and Timing (APNT). Mobile radar systems, especially those used in defense, depend on INS in situations where GNSS signals are disrupted or unavailable.

Maritime intelligence is required for a variety of reasons, including underwater infrastructure inspections and environmental monitoring, and its significance is only increasing.

Australia, April 2024 – Advanced Navigation, a global leader in AI robotics and navigation technology, is bringing humans closer to the ocean like never before – starting with a drone.

Oil rigs, those formidable structures used for extracting crude oil and natural gas from beneath the ocean floor, face an intriguing dilemma when they reach the end of their productive life. In accordance with international law, governments typically require retired oil rigs be treated as maritime waste and removed. However, there is a growing interest in repurposing them as artificial reefs.

In October 2023, Advanced Navigation deployed its micro-autonomous underwater vehicle (AUV) Hydrus off Rottnest Island, Western Australia. The purpose of the mission was to capture high-quality still imagery and 4K video, for the purposes of benthic inspection and 3D photogrammetry reconstruction.

There are several techniques for using USBL that are suited to different applications, each of which provides different advantages and results. USBL-squared (USBL2) is unique to Advanced Navigation. This article briefly explains each technique and the benefits of USBL-squared to help untangle any confusion on the subject.

JM Robotics adopt Subsonus USBL2 acoustic compass for accurate ROV heading in difficult, shallow water conditions.

Acoustic signaling is a method of using sound as a means of wireless underwater communications. Acoustics are used because radio waves, light waves and satellite signals cannot travel through water for any useful distance because of signal attenuation (reduction in amplitude) due to water density.

Peter Baker of Advanced Navigation shares some insights into the development and technology behind Hydrus – a micro-autonomous underwater vehicle (micro-AUV) that is revolutionizing the underwater drone industry.

Hydrus (AUV), a fully autonomous subsea drone, will revolutionize undersea research, survey and exploration by making data capture simple and accessible.
