Meridian Gyrocompass
Description
The Meridian Gyrocompass product range is suitable for the ever-changing needs of the modern bridge system. This includes highly accurate performance with low cost of ownership and system flexibility. Due to the Meridian's small size and fast settle time of less than 45 minutes, there are no limits to the type of vessel for which it is suitable.
The Meridian Gyrocompass can be installed as a stand-alone unit or, together with any of the TSS range of repeaters and ancillaries, it becomes a single, dual or triple gyro system. The Meridian can also be used as a retrofit unit.
The Meridian Standard provides a dynamic heading accuracy of 0.30° secant latitude RMS and a static heading accuracy of 0.10° secant latitude RMS. Whereas, the higher performance Meridian Surveyor provides a dynamic heading accuracy of 0.20° secant latitude RMS and a static heading accuracy of 0.05° secant latitude RMS.
For the full Meridian gyrocompass system, we offer a comprehensive suite of repeaters and ancillaries.
