Angular rate gyro accuracy is characterized by two parameters : scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates. This value is used to convert the voltage output from the gyro into an angular rate. System imperfections can cause small variations in the scale factor. These variations appear as a factor at the output of the gyro. Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point. It appears as an additive term on the gyro output, so any actual drift away from a given or predetermined value will cause the angular errors to accumulate. 2, record 3, English, - angular%20error

Angular velocity is the time rate of change of angular displacement. More simply it is a measure of how fast an object is rotating. For example, the measure of a skater’s spinning speed during a sit spin is called angular velocity. Angular velocity is calculated by subtracting the initial angular position from the final angular position and dividing by the time it took to get from the initial to final position. Angular velocity is measured in radians/second (SI units) or degrees/second or revolutions/second (English units). 4, record 4, English, - angular%20velocity

It is a cost-effective replacement for expensive-to-maintain gimballed attitude-directional-and rate-gyro-based systems, priced competitively with that 1960's technology but with up to five times the Mean Time Between Failure(MTBF).

Angular rate gyro accuracy is characterized by two parameters : scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates. This value is used to convert the voltage output from the gyro into an angular rate. System imperfections can cause small variations in the scale factor. These variations appear as a factor at the output of the gyro. Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point. 3, record 8, English, - scale%20factor

The scale factor is generally evaluated as the slope of the straight line that can be fitted by the method of the least squares to input-output data... For some sensors the scale factor may be expressed as a reciprocal. 2, record 8, English, - scale%20factor
