3 Terms and Definitions

The following terms and definitions apply to this standard.

Gyrocompass it includes all the basic elements of the design of complete sets of equipment compass. Including gyro compass heading as the combination of sensors and heading letter no transmission system two kinds.

True heading Through the vertical plane through the true meridian and the angle between the horizontal plane perpendicular to the bow and stern baseline.

Note 1. It is true north (000 °) in a clockwise direction of rotation of 360 ° is measured.

Note 2. When the gyro compass on the test bench test, this "true heading" is considered Luojing Ji alignment "true heading." In gyrocompass fitted using shift Luo Jingji when moving to correct the alignment device, according to the local latitude corrected.

Stable settled

Compass in a horizontal and stationary state, the difference between the read every 30min any three readings were in a stable state within the range of 0.7 °.

NOTE. Settling time refers to the elapsed between the first three steady start to read to the error in the initial bow recording time.

Stable point heading settlepointheading Compass stable (3.3) after every 10 readings 20min read average.
