TSS Meridian Subsea Gyrocompass – Available for rental, hire and ex-rental purchase from Ashtead Technology.
The Meridian Subsea Gyro provides a reliable, maintenance free operation with a MTBF in excess of 30,000 hours. 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 0.1° accuracy making the unit useful in a wider variety of subsea control, installation or monitoring applications.
