The Sperry Marine Gyro Sphere Supporting Liquid is a specially formulated maintenance fluid designed for use in Sperry Marine gyroscope compass systems, including the NAVIGAT X MK1, NAVIGAT X MK2, and compatible gyrosphere containers. It provides the correct buoyancy, damping, and electrical conductivity required for the gyrosphere to operate accurately and reliably within the gyrocompass assembly.

The supporting liquid allows the gyro sphere to float in a stable, precisely centered position inside the gyro container, minimizing friction and ensuring smooth movement. It also helps damp unwanted oscillations, supports electrical power transfer in applicable gyro container models, and maintains the compass’s high heading accuracy under varying sea conditions. Regular replacement of the supporting liquid is an essential part of preventive maintenance, helping to extend the service life and performance of the gyrocompass.
