Gyrocompass PGM-C-011 Surveyor

The gyrocompass PGM-C-011 Surveyor designed for hydrographic survey is a versatile and one of the most accurate mechanical gyrocompasses dedicated for commercial use.

The gyrocompass determines the ship heading relative to geographic meridian in the gyrocompass mode and the angle of displacement from the selected direction in the direct gyro mode.

A dynamically tuned gyroscope provides exceptional performance and reliability whilst a low cost of ownership as there is no need for routine maintenance.

Short settling time is one of the gyrocompass peculiarities.

The PGM-C-011 Surveyor can be used on any sea-going vessel thanks to the wide range of acceptable interfaces. Light, rigid and compact design of the gyrocompass makes it highly convenient for hydrographic applications.

The gyrocompass provides stable heading readings at rate of turn higher than 200 °/s that makes it ideal for use on fast survey crafts as well as for river/harbor navigation.

The PGM-C-011 Surveyor meets the following standards:
IMO A 424 (XI);
IMO 821 (19);
IEC 60945:2002-08;
ISO 8728-1997-06;
IEC 61162;
EMC Directive.
