Generally, the Earth rate [[omega].sub.ie], gravity acceleration g, and input
angular rate of inertial turntable [OMEGA] are regarded as references, which are compared with outputs of accelerometers and gyros of IMU.
Figures 3 and 4 present the LOS
angular rate and the Defender acceleration.
where [T.sub.a] represents the time constant of the armature circuit; [[??].sub.e] represents the coefficient of proportionality between the electromotive force and the
angular rate of the motor; [k.sub.PWM] represents the transfer constant of the linearized PWM; [U.sub.PWMi] represent voltages at PWM input.
The miniature ARS PRO
angular rate sensor by DTS is designed to capture precision
angular rate data, even in high-energy environments including blast protection and crash testing.
where [[mu].sub.0]--constant coefficient, which is determined experimentally; d[[phi].sub.H](t)/dt and d[[psi].sub.H] (t)/dt--hull
angular rate in elevation and azimuth axes.
