SERVO METER WITH CORRECTING FILTER Russian patent published in 2000 - IPC

FIELD: radio engineering systems for measurement of trajectory parameters of flight vehicles, such as range-speed, speed-acceleration, angular coordinate - rate of change of angular coordinate. SUBSTANCE: correction of predicted values of the followed up coordinate is carried out in this meter, containing the channels of evaluation of the measured coordinate and the rate of its change, due to introduction of switching. EFFECT: enhanced stability of servo meter functioning, accuracy of evaluation of the followed up coordinate by 15 to 50%, and reduced time of transient processes at great errors of primary measurements by 1.3 to 1.7 times. 1 dwg
