RWLT GIB - Navigation buoy Device specification |
KEY FEATURES
- High-performance combined GPS/GLONASS receiver
- Rugged, durable, easily noticeable housing
- Automatic activation in water
- Long battery life of up to 24 hours
- Reliable and noise-resistant digital broadband underwater acoustic communication technology
DESCRIPTION
The RWLT GIB navigation sonobuoy of the RWLT system, in a set of four such devices, forms a floating long navigation base that supports positioning of the RWLT Pinger pinger or the RedPhone diver telephone station.
The device has a float-and-spar (spar buoy) design and has no air cavities or controls: it switches on automatically when immersed in water, and switches off automatically when the buoy is taken out of the water.

1 Not including the receiving transducer on the cable, with a total length of 1.6 m.
2 With a new, fully charged battery, at an ambient temperature of 20 °C.
3 A parameter that determines the maximum range at which signal reception is possible, based on the electro-acoustic parameters of the transmitter and receiver, the spatial decrease in the intensity of sound energy, attenuation in the medium and the acoustic noise level.
4 The buoys are placed on the water surface in a convex polygon so that the distance from each buoy to any other does not exceed the specified value.
5 The immersion depth of the pinger must not exceed the dimensions of the navigation base.
6 Achieved in the absence of interference, in open areas.
