Seafarers the world over have relied on SG Brown gyrocompasses for almost 100 years. The Meridian Subsea uses a Dynamically Tuned Gyro (DTG) element, which provides exceptional performance and accuracy and removes the need for routine maintenance, significantly reducing cost of ownership.
The high accuracy heading output can be maintained for turn rates in excess of 200° per second making the system ideal for operation in even the most hostile subsea environments. The design of the Meridian Subsea is simple yet highly robust and the fast spin-up time of less then 45 minutes allows for vastly increased efficiencies over earlier mechanical gyro technologies.
The Meridian Subsea may be upgraded to the Subsea RP with addition of a Roll Pitch Module. This enables output of roll and pitch data with up to 0.1° accuracy making the unit useful in a wider variety of subsea control, installation or monitoring applications.
Also optional in either the Subsea or Subsea RP models is the addition of an integral battery back-up module. This can cover short-term power supply loss and power supply switch over.
