In-flight receiver calibration of the Ganymede Laser Altimeter (GALA) by passive Earth observations

Abstract. Post-launch characterization of the receiver telescope of the laser altimeter is essential for achieving precise georeferenced planetary measurements and for radiometric calibration to passively measure surface reflectance. For the Ganymede Laser Altimeter (GALA) aboard...

Practical robust loop-shaping design method for triple-stage HDD actuator control under stroke constraints in data-center storage applications

With the continuous growth of data storage demand, precise and stable magnetic-head positioning in hard disk drives (HDDs) remains essential. This paper proposes a disturbance-rejection-oriented control design for triple-stage actuator (TSA) systems. The approach employs Bode-plo...
