Pointing & Motion Control Systems

Sierra Space is an industry leader in precision, low-disturbance pointing systems for space applications.

Sierra Space develops a number of single- and dual-axis pointing systems for spaceflight tracking, navigation and positioning functions for antennae, solar array drives/mechanisms, optical telescopes and instrument mechanisms.

Our pointing systems are qualified and flight-proven with NASA programs, commercial and military satellites and the ISS. Although we specialize in custom-engineered, open- and closed-loop solutions, our list of qualified motors, actuators, gimbals and drive electronics has grown into a substantial portfolio capable of supporting a wide range of applications and sizes with minimal non-recurring effort required.
