چکیده
____________________________________________________________________ The calibration of accelerometers, angular rate sensors, and inertial measurement units (IMU) increases the accuracy of their measurements. For artillery rounds and most rockets, measurements are acquired while the body is spinning. By the comparison of the sensor output to known input, calibration is accomplished. Calibration requires a model of the sensor. The model represents the measurement process. Model selection, calibration equipment, and data selection affect the usefulness of a calibration for a given mission. Calibration is model fitting for a specific mission or class of missions.

متن کاملInertial Sensor Error Reduction through Calibration and Sensor Fusion
This paper presents the comparison between cooperative and local Kalman Filters (KF) for estimating the absolute segment angle, under two calibration conditions. A simplified calibration, that can be replicated in most laboratories; and a complex calibration, similar to that applied by commercial vendors. The cooperative filters use information from either all inertial sensors attached to the b...
