Zima2-RK - Zima2 USBL responder-beacon Device specification |
KEY FEATURES
- Operating depth up to 1000 m
- Communication range up to 30001 m
- Highly reliable digital underwater acoustic communication resistant to multipath propagation
- Code division multiple access - up to 16 isolating addresses
- Low power consumption (Rx/Tx) 0.33/10 W

DESCRIPTION
Zima2-RK - responder-beacon of the ultra-short baseline navigation system Zima2 USBL for operation at depths up to 1000 m.
The device is designed to be placed on an underwater object in order to determine the location of this object in real time using the direction-finding antenna Zima2-BK.

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 Excluding the weight of the transducer. The device is supplied with the transducer RT-1.524525-1-FF.
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.
