COMPASS – TSS MERIDIAN Gyro Compass – Survey version

thông itn

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 standalone 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.
