Underwater acoustic navigation system RedWAVE is designed to provide navigational data (absolute geographical coordinates and depth) of various underwater objects in a submerged state: remotely operated underwater vehicles (ROV), autonomous underwater vehicles (AUV), as well as divers (in case of using diving version of the equipment).
The principle of the RedWAVE system performance is similar to the principle of global satellite navigation GPS and GLONASS operation. The main difference is that the role of navigation satellites is performed by small and lightweight floating buoys – RedBASE – satellite navigation signal responders. In this case, the coordinates are generated directly on the navigation receiver RedNODE, which is an acoustically passive device. This type of system arrangement allows to simultaneously provide navigation data with an unlimited number of navigation receivers with the support of one set of buoys in one water area.
In the diving version, the RedNODE receiver is aggregated with a diver module interface, equipped with a high-contrast OLED screen and piezo switches. The name of this device is RedNAV and it allows the diver to determine the geographic location in the submerged state, without the need for surfacing and the use of remote GPS antennas on the cable.
