Zima2-L - LBL transceiver of the Zima2 LBL navigation system Device specification |
KEY FEATURES
- Extremely small size and weight
- Communication range up to 30001 m
- Reliable digital underwater acoustic communication resistant to multipath propagation
- Low power consumption (Rx/Tx) 0.33/10 W
- Built-in pressure/temperature sensor
- Patented* monoblock design
DESCRIPTION
Zima2-L - transceiver of the long baseline navigation system Zima2 LBL.
The device is designed to be placed on an underwater object in order to determine the location of this object in real time using a navigation base formed by three fixed reference points - responder-beacons Zima2-R.
The transceiver interrogates the responder-beacons and measures the range to them; based on these data, the system calculates the position of the transceiver in a local or absolute (geographic) coordinate system.
* Patent RU2659299C1.

- 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. The maximum communication range is not equivalent to the maximum operating range of the navigation system.
- 2 The value was obtained in a laboratory static experiment, without taking into account the multipath propagation effect.
- 3 The value can be changed on request.
- 4 Obtained from the results of a full-scale static experiment in a body of water, with a distance between the reference points of 100 m.
- 5 With the minimum size of the navigation base, the transceiver is 50 m away from the center of the navigation base.
