WebbFast Steering Mirrors, or FSM for short, are physical systems composed of a reflective mirror, a pair of motion-tracking sensors, a displacement actuator, and a processing unit that aid in receiving an incoming signal beam at the correct angle or redirecting it in a specific direction. The mirror is mounted on top of a rotating structure with ... Webb3 apr. 2024 · Line-of-sight pointing control with JWST requires the interconnected operation of star trackers, inertial reference units (gyroscopes), fine Sun sensors, reaction wheels, the telescope's fine steering mirror, the fine guidance sensor, various target acquisition modes in science instruments, flight software in both the spacecraft and …

Optotune’s dual axis fast steering mirror (FSM) offers the benefit of large deflections and large mirror size in a compact package. The actuator is based on proven voice-coil technology. A built-in position feedback allows it to be accurately controlled with a standard PID controller.
Webb7 jan. 2024 · Engineers must first release mechanisms that held the wing in place for launch, in order to allow the wing to deploy. The panel then rotates into position, a motor-driven process that takes about five minutes. Once the wing is extended, engineers begin a meticulous, two-hour process to securely latch it into place.
