- Maximum immersion depth of the transducer up to 1000 m
- Highly reliable digital underwater acoustic communication resistant to multipath propagation
- Code division multiple access - up to 23 isolating addresses
- Highly reliable digital underwater acoustic communication

DESCRIPTION
Zima-R OEM - responder-beacon of the ultra-short baseline navigation system Zima USBL.
The device is designed to receive remote control commands from the base station Zima-B - direction-finding base station, to transmit telemetry information to the base station Zima-B - direction-finding base station, and to determine the direction, both to the responder-beacon (for the base station) and to the base station (for the responder-beacon), and the mutual distance.
The device is supplied as a printed circuit board assembly for installation inside the user’s one-atmosphere (normobaric) housing and is equipped with a transducer for depths up to 1000 m.
The depth can be set either by the user system, or the device can work with separately supplied sensors.
Extremely small size, low power consumption and ease of use make the direction-finding system Zima USBL an ideal solution for working with autonomous and remotely controlled vehicles, as well as for determining the relative position of divers.

1 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.
2 The value given is the maximum immersion depth of the transducer.
3 The value was obtained in a laboratory static experiment, without taking into account the multipath propagation effect.
4 The value can be changed on request.
5 Obtained in laboratory conditions in a static experiment.
