The system has been designed to automatically switch its throughput to that of another gyro should the principal one fail. It can be connected to up to four gyrocompasses so that navigation and positioning systems are DNV compliant.
The changeover system has been designed to ensure that equipment such as DP (dynamic positioning) control centres, ECDIS and voyage data recorders are never without a gyro input.
It consists of an enclosure for the retransmission circuits and up to two separate display units. The panels show the condition and performance of all gyros in use.
The system can switch automatically from one gyro to another, though it can also enable the manual changeover of gyro throughput if required.
The changeover system is suitable for use with Teledyne TSS Meridian gyro compasses but can also be used with other makes of gyrocompass that use the same data output formats (16 IEC 61162).
