Scientists Are Developing A Really Cool New Navigation System To Help UUVs Find Their Way In The Ocean Depths

A new video place out this week by the University of Washington’s Applied Physics Laboratory shows how scientists are developing special navigation techniques that permit unmanned underwater vehicles to navigate the ocean depths for longer lessons, gathering scientific records as they inch.

A Seaglider UUV was deployed and retrieved all the plan in which thru experiments within the Santa Monica Basin off Southern California. The Seaglider in actuality “flies” underwater, altering its buoyancy robotically to tumble and ascend on shallow wing paths, in accordance to the Laboratory.

Seagliders comprise unexcited records all the plan in which thru total ocean basins, navigating their potential by getting GPS fixes as soon as they ground on the stay of every dive cycle.

APL-UW Valuable Analysis Engineer Sarah Webster is serving to colleagues from the Woods Gap Oceanographic Institution take a look at an acoustic undersea navigation system on the Seaglider that would permit it to navigate the ocean depths for longer stretches with out surfacing.

Here’s the plan in which it’s done: An independent boat transmits its peril to Seaglider at standard intervals, and the UUV uses a terribly, essentially appropriate clock to calculate the one-potential slither time and perspective of that acoustic place to repair its peril relative to the bottom automobile.

Experiments disclose that this acoustic system improves Seaglider’s undersea peril estimate accuracy in comparison with calculations based mostly handiest on GPS fixes on the bottom. Laying aside frequent journeys to the bottom also increases the quantity of time Seaglider can use within the deep oceans.

The analysis and pattern of this functionality was subsidized by the National Science Foundation and National Oceanic and Atmospheric Administration.

Strive the video below to comprise a study how the system works.
