Hello everyone!
We're Underwater Communication & Navigation Laboratory (UC&NL). We develop and manufacture a number of underwater wireless navigation & communication solutions.
Let us tell you about our unique underwater navigation system RedWAVE. This system provides simultaneous positioning of an unlimited number of objects in the water area with a nominal accuracy of 0.5 m at distances up to 2 km.
To know more, read the text below.
Modern life is hard to imagine without the GPS and GLONASS satellite navigation systems. However, radio waves do not penetrate water, and until recently, underwater navigation was available only to the military or in the form of fabulously expensive industrial solutions.
Underwater, inertial navigation is possible based on the calculation of an object’s movement from a known point on the surface, but even the most expensive systems give an error accumulation of hundreds of meters in half an hour. To understand all the difficulties in creating a good inertial system, imagine that you are blindfolded and driven around the city by car. Memorizing all the turns, acceleration and deceleration, you try to figure out where you are. But over time, you will not only cease to understand the movement of the car, but also the speed at which it is moving.
There are also acoustic signals in water. Our cohabiters on the planet who live in the oceans long ago learned to use sound for underwater navigation instead of sight.
In the last five to seven years, a lot of information has appeared online promising consumers various extents of "real underwater GPS,” but officially no one has yet announced the start of sales. No one, that is, except us.
The Underwater Communication & Navigation Laboratory (UC&NL) team set itself the goal of making a reliable system that offers similar functionality to that of regular GPS and GLONASS, is easy to use and works underwater.
We took the functioning of satellite navigation systems as a basic principle, but instead of satellites, four small RedBASE buoys on the surface of the water retransmit the satellite signal underwater in the form of acoustic waves. This type of navigation system is called a long base-line, or LBL.
It takes only 10-15 minutes to position the buoys on the surface of the water before diving. After that an unlimited number of divers wearing the RedNAV navigation device or underwater robots fitted with RedNODE navigation receivers can simultaneously determine their exact geographical position underwater. Like GPS navigators, the RedNAV navigation device saves the full route of the diver's movements. Divers can also upload up to 20 points along the route in advance via Bluetooth. Once underwater, divers can mark their location with a single click of a button. It can then be unloaded from the device together with the route, saved or uploaded to Google Earth.
Never before has underwater navigation been so close in terms of simplicity and accuracy to regular overland navigation. The navigation receiver is available in two versions: for divers, with information output to an OLED display, and for underwater robots. A unified protocol with standard GPS/GLONASS navigators makes working with our device virtually no different from working with conventional GPS modules.
The unique technology of digital broadband hydroacoustic noise-immune communication makes it possible to obtain position accuracy of about one meter, even in difficult conditions with strong signal reflections (this effect in acoustics is called multipath).
Instead of promises, we can show routes received by our devices in real bodies of water:
On this route, you can see how the diver passed near the buoys with ease and returned to the starting point.
Below is the route of another diver, who swam more than 200 meters and returned along exactly the same route, retracing his steps to within less than one meter:
The RedWAVE system currently has no analogues in the world. Its price tag is far lower than the most basic and inexpensive imported industrial solutions, while it is incomparably advanced in terms of functionality and precision.
