On the bias and flicker noise of inertial sensors

Posted on April 30, 2012 by odtu_ee

What is bias anyway? Commonsense says that it is the sensor output when the input is 0. Therefore, if you align your gyroscope to the East and read 2.5434V at the output, you may think that you can call this … Continue reading →

MEMS gyroscopes and their sinusoidal errors.

Posted on November 3, 2011 by odtu_ee

Almost all low cost MEMS gyroscope outputs are contaminated with additive sinusoidal noises. However, these additive sinusoidals are hindered by the additive white noise (ARW) most of the time. Therefore, these components are usually missed in the inertial sensor models … Continue reading →
