WAYU GIB - Navigation buoy Device specification |
KEY FEATURES
- Minimum dimensions and weight
- Strong and durable maintenance-free housing
- Automatic activation in water
DESCRIPTION
The WAYU GIB navigation sonobuoy of the WAYU system, in a set of four such devices, forms a floating long navigation base that supports positioning of the WAYU Pinger pinger.
The device has a one-piece design, is made of high-strength polyurethane and polypropylene, and switches off automatically when it enters the water. It does not require any settings or calibrations. Buoyancy is provided by an easily noticeable float made of ethylene-vinyl acetate (EVA).

1 Not including the receiving transducer on a 1 m cable, not including the float (Ø x h) 125 x 160 mm.
2 With a new 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 Achieved in the absence of interference, in open areas. The receiving antenna may need to be raised several meters higher.
