drift error

[′drift ‚er·ər]
(computer science)

Furthermore, noises, drift error, sensor axis misalignment error must be taken into account.
The first one is the current sensor drift error and the other is the high current signal interference.
Comparing with the classical method, the proposed temperature method could reduce the temperature drift error typically from 0.
Allan variance is a method of representing root mean square (rms) random drift error as a function of average time (IEEE .
Zero Drift Error = [+ or -]Sensor Zero Drift (W)/Signal Power (W) x 100 %
The heading angle is determined, based on the sensor yaw angle, and its drift error is compensated by means of the sensor fusion with the RTK-GPS.
where c represents the speed of light, t represents the clock offset error state and [delta]t is the clock drift error state.
The frequency deviation is [+ or -]50 MHz, which is a wider frequency window than the combined linearity and frequency drift error.
Each IC also provides an on-chip temperature sensor which allows designers to compensate for temperature drift error and increase system accuracy.
Fluxgate transducers use an advanced magnetic current-measurement principle that inherently cancels or nulls many of the offset and drift errors that appear in simpler current-sensing techniques.
