3 Terms and Definitions

The following terms and definitions apply to this document:

turntablerotatingtable Rate turntable ratetable A rotating device with a gyroscope mounted during the measurement:

earth rotation rate earthrate the angular rate in inertial space due to the Earth's rotation:

Note: According to the International Earth Rotation and Reference System Service (IERS), the angular rate of the Earth in inertial space is defined by sidereal day, which is 23 hours and 56 minutes Clock 4:098903691 seconds: Therefore, the angular velocity of the earth in inertial space is about 15:04°/h: For more information on definitions, refer to the IERS web website (http://www:iers:org):

Scale factor the ratio of the output voltage or output digital signal of the gyroscope to the loading angular rate, the unit is V/[(°)/s] or bit/[(°)/s]:
