ATeledyneTSSNavigationSystemsDatasheet

The Meridian gyrocompass product range is suitable for the ever-changing needs of a modern integrated navigation 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 Meridian range of repeaters and ancillaries, it becomes a single, dual or triple gyro system. The Meridian can also be used to replace many existing gyrocompasses as a retrofit unit.

For simple installation the Meridian offers a large array of digital and analogue outputs plus easy to use set-up and self-test modes that are activated via the control unit. The versatility and flexibility of the Meridian can be clearly

demonstrated with the remote control unit option which gives freedom to install the main unit in the most convenient location whilst installing the remote control unit where it can be seen and regularly used.

Unlike other marine navigation gyrocompass currently available, the Meridian has a maintenance-free dry element with a meantime between failure of more than 30,000 hours; and post- installation there are no scheduled annual maintenance and servicing costs.

MeridianStandard

The heart of the Meridian gyrocompass is the element, which is a dynamically tuned gyroscope (DTG). The DTG is a high precision technology which, due to its size, accuracy, reliability and shock resistance, is used in many different applications.

The guaranteed accuracy of the Meridian gyrocompass is obtained through specialised high quality engineering. This gives exceedingly stable heading and means that the gyro will follow a high turn rate of up to 200° per second.

MeridianSurveyor

The Meridian Surveyor boasts a wide range of interfaces to enable use on any marine vessel. The unit utilises a DTG gyro element which provides exceptional performance with an accuracy unmatched by even the latest fibre optic designs.

Note: Subsea variants also available -see separate data sheet.
