bias: (A) laeerleronserrr) The average ova a specified time o(accelerometer output measured 21 specified operating conditions that has no correlation with input acceleration or rotation. Bias is expressed as mis in SI umts.h (B) (gxro) The average over a specified time of gyro output measured at specified operating cundiiiotsx that has no correlation with input rulaison ut acceleration. Baits is typically expressed in h.

bias asymmetry (gym, aecelernmeter): The difference between the baa for positive and negative truts,
expressed as md/s (gyro) or m’s (aeceleronneter) in SI units.’
bias irsstahilits (gyro. acceimninrier): The rantkrrn sanatron in bias as computed over specified finite sample tame and averaging time intervals, Thts nonstationary (evolutionary) process is chsacterized by a lifprrwa spectral density. It ts exprcssed as radis (gym) or nfl’ (accelerometer) in SI unit.

binan rnmaiog (mechanical gyro, acceleronwter): A torquing mechanintion that uses only two ttsrqtaer current levels that are irsually positive and negative of the same magnitude; no sustained rero current or off condition exists. The positive and negative current periods can be either discrete pulses or duration- modulated pubes In the case of zero input (acceleration or angular rate), a discrete pulse system will produce an equal number of positive and negative pulses. A pulse-duiauon-nsodulated system will produce positive and negative current periods of equal dtaration foe zero input. Binary torquing delivers constant power to a acassut torquer tat conipsed to variable power temiwy torquingl and results in stable themssal gr.tslients for all utputs.
caging (isseetsanleal gyro): The process of orienting and tnecltatsieally locking one or more gyro axes or gimbal axes to a reference position.
capturing tmeelsa.leal gyro. accelerometer): The use of a torquer (forcerl tn a veno loop to restrain a gyro gimbal. rotor, or accelerometer proof nsass to a specified reference position.
case (gyro, accelerometer): The horning or package that encloses the sensor, provides the mounting surface, and deftnes the reference axes.

composite error (gyro, accelerometer): The maximum deviation of the output data from a specified output function Composite error is due to the composite efkcts of hysteresis, resolution, nonlineanty nonrepcatability. and other uncertainties in the output data It in generally expressed as a percentage of half the ouqsut span See: laiput-ouirpuit characteristics.IEEE 528 pdf download.
