|RedNODE - Underwater navigation receiver
RedNWAVE - the only system to date that implements the so-called “underwater GPS”: following exactly the ideology of GPS and other satellite systems, allows an unlimited number of underwater objects to determine their geographical location at the same time.
RedNODE - navigation receiver of the RedWAVE system, receiving hydroacoustic navigation signals from buoys, determines its own geographical coordinates, which it transmits via a serial interface (UART) to control system. At the same time, the message format used in conventional GNSS receivers is emulated, which ensures maximum simplicity of integration.

1 For devices released after June 2020. For devices previously released, 5 V.
2 A parameter that determines the maximum range at which a signal can be received, based on electro-acoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the medium and the acoustic noise level.
3 The value obtained without taking into account the multipath effect.
4 The value is obtained by measuring in a real water body with buoys and navigation receiver fixed, within 60 minutes.
5 The value may depend on the correctness of the user setting the salinity of the water.
6 By agreement, delivery with an RS422 interface converter mounted on a cable in an unattended urethane housing is possible.
