The 106G is an additional GPS receiver designed to survive immersion that complements the operation of a nearby standard subsea positioning beacon.

This arrangement is suited to coastal construction tasks where submersible vehicles may periodically break the surface.

Whilst submerged, positioning data is provided by a standard positioning beacon but once the vehicle breaks the surface the 106G takes over to provide the information required, typically cabled to the vessel based positioning system via the vehicle umbilical.
