Operation of Deeper is based on echolocation and wi-fi technologies. Echolocation is a method for detecting and locating objects submerged in water. When a sound signal is produced, the time it takes for the signal to reach an object and for its echo to return is issued to calculate the distance between the sonar and the object.
Sonar Systems: Acoustic homing is used in many underwater sonar systems such as on submarines, ships, and fish finders. These systems use sound waves to detect underwater objects, as well as measuring the object's distance and determining the object's relative position.

USBL (ultra-short baseline, also known as SSBL for super short base line) is a method of underwater acoustic positioning.A USBL system consists of a transceiver, which is mounted on a pole under a ship, and a transponder or responder on the seafloor, on a towfish, or on an ROV.
Long baseline systems get their name from the fact that the spacing of the baseline transponders is long or similar to the distance between the diver or vehicle and the transponders. [3] That is, the baseline transponders are typically mounted in the corners of an underwater work site within which the vehicle or diver operates.
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
Both of these techniques, when used in water, are known as sonar; passive sonar and active sonar are both widely used. Acoustic mirrors and dishes, when using microphones, are a means of passive acoustic localization, but when using speakers are a means of active localization. Typically, more than one device is used, and the location is then ...
Sonar (sound navigation and ranging or sonic navigation and ranging) [2] is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances , communicate with or detect objects on or under the surface of the water, such as other vessels. [3]
Bistatic sonar is a sonar configuration in which transmitter and receiver are separated by a distance large enough to be comparable to the distance to the target. Most sonar systems are monostatic , in that the transmitter and receiver are located in the same place.
