RWLT GIB

The RWLT GIB navigation hydroacoustic buoy is the foundation of the RWLT system: a set of four buoys forms a floating navigation base and provides positioning for the RWLT Pinger beacon or the RedPhone-DX diver's telephone station.

The buoys operate at a distance of 30 to 1500 m from each other, are equipped with a combined GPS/GLONASS receiver, and require no setup — simply place the buoys on the surface of the water and switch them on.

The device follows a float-and-fin design with no air cavities or controls: it switches on automatically when submerged in water and automatically switches off when removed from the water. The housing is light and strong, and is easily replaced if mechanically damaged.

The buoy resists interference even in shallow water thanks to broadband digital hydroacoustic communication technology. The working temperature range is from -10 to +50 °C.

  • High-performance combined GPS/GLONASS receiver
  • Rugged, durable, highly visible housing
  • Automatic activation in water
  • Long battery life — up to 24 hours
  • Reliable, interference-resistant digital broadband hydroacoustic communication technology
  • Relays telemetry from the RWLT Pinger — depth, water temperature and battery voltage
  • Operates at a distance of 30 to 1500 m from other buoys in the set

How RWLT GIB works

When developing RWLT GIB, we drew on our experience designing and operating the flagship RedWave system. The principle is similar — a set of four buoys forms a floating navigation base and provides positioning for the pinger.

01

Key characteristics

Easy to use — one person in a small boat can deploy and retrieve the navigation base. Reliable and durable — the buoy housing is light and strong, and is easily replaced if mechanically damaged. Resistant to interference even in shallow water thanks to broadband hydroacoustic communication technology. Wide working temperature range — from -10 to +50 °C.
