Abstract

Provided herein are systems and methods for minimizing jitter. A method for minimizing jitter for at least one sensitive component on a spacecraft includes receiving a rotary actuator speed command indicating a rotary actuator speed for a stepper motor on the spacecraft, setting a stepping mode of the stepper motor to one of a first stepping mode and second stepping mode based on a preconfigured data structure which encodes a corresponding stepping mode for the rotary actuator speed based on a pre-determined jitter-sensitive frequency band, wherein the first stepping mode and the second stepping mode each maintain harmonics of the spacecraft outside of the jitter-sensitive frequency band. A system includes a stepper motor, an onboard processing unit to generate rotary actuator speed commands, and a mechanism control electronics (MCE) subsystem, wherein the MCE subsystem controls a stepping mode of the stepper motor based on a rotary actuator speed command.
