Query: A Calibration Algorithm for Microelectromechanical Systems
  Accelerometers in Inertial Navigation Sensors   In the present work we develop an algorithm for calibrating MEMS sensors,
which accounts for the nonorthogonality of the accelerometers' axis, as well as
for the constant bias and scaling errors. We derive an explicit formula for
computing the calibrated acceleration, given data from the sensors. We also
study the error, that is caused by the nonorthogonality of the axis.
