RWLT GIB - Navigation buoy Device specification |
KEY FEATURES
- High performance combined GPS/GLONASS receiver
- Rugged, durable and easy to see body
- Automatic activation in water
- Long battery life up to 24 hours
- Reliable and noise-resistant digital broadband hydroacoustic communication technology
DESCRIPTION
The navigation sonobuoy RWLT GIB of the RWLT system, as part of a set of four such devices, forms a long floating navigation base, with the support of which the positioning of the pinger RWLT Pinger or diving telephone exchange RedPhone. The device is made according to the float-feather scheme, has no air cavities and controls: it turns on automatically when immersed in water, and when the buoy is removed from the water, it automatically turns off.

1 Without taking into account the hydroacoustic receiving antenna 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 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.
4 Buoys should be located on the surface of the water in a convex polygon so that the distance from each buoy to any other does not exceed the specified value.
5 The dive depth of the pinger should not exceed the dimensions of the navigation base.
6 Achieved in the absence of interference, in open areas.
