RWLT GIB - Navigation buoy Device specification |
KEY FEATURES
- High performance combined GPS/GLONASS receiver
- Robust, durable, highly visible body
- Long battery life up to 24 hours
- Reliable and robust digital broadband hydroacoustic communication technology
DESCRIPTION
Navigation buoy RWLT GIB of the system RWLT as part of a set of four such devices forms a floating long navigation base, with the support of which positioning of the pinger RWLT Pinger or underwater wireless telephone RedPhone is provided.
The device is made in the form of a plastic cylinder with dimensions Ф150х600 mm with a receiving hydroacoustic antenna on a cable.
The device has positive buoyancy and a load-carrying eye for anchor attachment.

1 Without taking into account the height of the radio antenna (180 mm) and the acoustic receiving antenna on a cable 1.5 m long.
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
electroacoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the environment
and the level of hydroacoustic noise.
4Buoys should be located on the surface of the water in a convex polygon so that the distance from each buoy
to any other did not exceed the indicated value.
5 Pinger’s immersion depth should not exceed the size of the navigation base.
6 Achieved in the absence of interference, in an open area.
