Any sensor offset drift error
will be the same for both measurements, since the sensor is the same for both measurements.
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
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.
01 dB/[degrees]C measurement stability to minimize drift errors
, and it offers integrated QuickCal calibration capability.
