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 hovering autonomous underwater vehicle (micro hovering 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.

DOF Subsea use dual Subsonus USBL positioning to eliminate complexities and cost of deployment for compact ROV.

Australia, 1st April 2022 – Advanced Navigation, one of the world’s most ambitious innovators in AI robotics, and navigation technology, is announcing Hydrus – a revolution in underwater drone technology, developed to open exciting frontiers in ocean exploration around the world.

Advanced Navigation has today released the second generation of their highly successful satellite compass. GNSS Compass is a plug-and-play solution that provides accurate position, heading, and time in a self-contained unit.

Geosurvey Mexicana is now able to tap new markets with Advanced Navigation’s Subsonus USBL for an accurate underwater positioning system.

There are several methods to determine heading in navigation when using an Attitude Heading Reference System (AHRS) or an Inertial Navigation System (INS). As such recommending an appropriate heading source should be based on typical application requirements. These are indicative but should be evaluated fully for individual applications.

Nortek uses Advanced Navigation GNSS Compass for accurate heading to assist ADCP in their new survey package. See our GNSS Compass in action!

The Desert Wave teams finishes 3rd at Robosub 2019, thanks to a Subsonus USBL provided as part of a sponsorship for their UAV.
