Modulus introduces innovative subsea GPS receiver

The 106G is a GPS receiver designed to survive immersion that complements the operation of a second standard subsea positioning beacon located nearby on the same vehicle.  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 acoustic positioning beacon but once the vehicle breaks the surface the 106G takes over  to continue to provide the positioning  information, typically cabled to the vessel based positioning system via the vehicle’s  umbilical.
