The Meridian gyrocompass 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 is no limit to the type of vessel for which it is suitable.
The Meridian gyrocompass can be installed as a stand-alone unit for GMDSS, or together with our comprehensive range of repeaters and ancillaries, it becomes a single or dual gyro system within a fully integrated bridge system. For simple installation the Meridian offers a large array of digital and analogue
outputs plus easy to use digital setup and self-test modes that are activated via the control unit.
The versatility and flexibility of the Meridian Gyrocompass can be clearly demonstrated with the remote control unit option which is supplied with the gyrocompass system. This gives freedom for the operator to install the main unit in the most convenient location whilst installing the remote control unit where it can be seen and regularly used.
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. With a standard connection to GPS, Loch and the acceptance of very fast rate of turn (up to 200° per second), the heading is very stable and the compass can be installed on vessels of any size. The DTG is a maintenance-free dry element with a mean time between failure of 30,000 hours.
