Allan variance is a method of representing root mean square (rms) random drift error as a function of average time (IEEE .
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.
Each IC also provides an on-chip temperature sensor which allows designers to compensate for temperature drift error and increase system accuracy.
Long term drift errors are corrected in real time so that the device is zeroed out prior to operation.

Autozeroes transducers preload and drift errors each cycle.
Therefore, drift errors due to the test equipment itself are very low.
The NI FlexII ADC incorporates patented NI methods for reducing the linearity and temperature drift errors inherent to multi-bit sigma-delta converters to achieve unprecedented dynamic range at high sample rates.
