Micro-Electro-Mechanical Systems (MEMS) technology gyroscope
1 Scope
This document specifies the terms and definitions, ratings, performance parameters and measurement methods of gyroscopes:
Gyroscopes are mainly used in consumer electronics, industrial and aerospace, etc: Gyroscopes make extensive use of MEMS and semiconductor laser technologies:
2 Normative references
This document has no normative references:
3 Terms and Definitions
The following terms and definitions apply to this document:
3:1
turntablerotatingtable
Rate turntable ratetable
A rotating device with a gyroscope mounted during the measurement:
3:2
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):
3:3
Scale factor scalefactor
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]:
4 Basic ratings and characteristics
4:1 Classification of gyroscopes
Table 1 shows the uses of gyroscopes classified by application field:
Table 1 Classification of gyroscopes
category content
1 Mainly used for consumer products, no requirement for zero offset
2 Mainly used for industrial purposes, set an appropriate value range for the zero offset
3 Mainly used for aerospace purposes, it can detect the rotation speed of the earth
