1.5 Motion Sensor MS-100 (option)
The MS-100 measures ship’s pitching and rolling angles with sensor using the principles of the
gyroscope. The MS-100 is free from error caused by ship’s vertical and horizontal motion.
Therefore, it can be installed at any convenient location. However, ship’s semi-permanent
inclination due to loading imbalance cannot be detected. Compensate for this as described in
Chapter 3.
1.5.1 Mounting considerations
Vibration in the mounting area should be minimal.
Locate the unit away from areas subject to water splash.
The ambient temperature should not exceed 50 °C
1.5.2 Mounting procedure
Orient the FORE mark on the unit toward the ship’s bow and mount the unit level to within 5° in
all direction. For the offset, see Chapter 3.
