WAYU Pinger - Navigation pinger beacon Device specification |
KEY FEATURES
- Maximum ease of maintenance
- Automatic activation in water1
- Minimum dimensions and weight
- Patented* monoblock design
DESCRIPTION
The WAYU Pinger navigation pinger beacon of the WAYU system is placed on the object to be positioned: an ROV, AUV, diver or other underwater object, and emits a periodic navigation signal that is received by four floating WAYU GIB navigation buoys. The geographic position of the pinger is determined from the navigation signal. The device can be powered by the carrier or equipped with an autonomous power source.
* Patent RU2659299C1.

1 In the standalone version
2 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.
3 The maximum communication range is achieved at a supply voltage of 12 ± 1 V
4 The current consumption is calculated for a supply voltage of 12 V. The signal emission period is 2 seconds, the signal duration is 10 ms
5 With a new, fully charged battery at an ambient temperature of 20 °C
