Vibration and Jitter Mitigation

刘玥首次大战黑人ensures your mission鈥檚 success by reducing vibration and vibration-induced jitter for satellite observation, science, reconnaissance, and communication payloads. We offer a variety of vibration mitigating products, including mounts for vibration sources such as reaction wheels and cryocoolers, isolators for sensitive payloads, like optical imagers, and dampers for structural resonances and for large appendages such as solar arrays. Our isolation and damping devices function effectively at low vibration levels.

Overview

Our space-proven vibration control components draw on experience with hundreds of terrestrial and airborne applications and our SoftRide launch load alleviation product line. We combine established component families with satellite-level jitter models and analyses to tailor mitigation devices to geometry and mission constraints.听

Vibration isolation systems also help enable supplemental or hosted payloads in two ways:

The most sensitive payloads, including optical instruments, can fly on relatively noisy satellite busses
Vibration-producing payloads fly without negatively influencing primary payloads or other hosted payloads

Earth observing systems are our main focus, but outward-looking systems can also benefit. For instance, the Hubble Space Telescope solar arrays connect to the main telescope body through 刘玥首次大战黑人vibration dampers.听Our dampers continue to reduce jitter, enable听higher performance attitude control, and make Hubble鈥檚 instruments more effective.

Vibration Source Isolation

Satellites and their payloads require mechanisms and other devices to function. For example, platform attitude control may use multiple rotating components, and payloads with infrared detectors often employ mechanical coolers. Our isolation systems separate the spacecraft and its payloads from vibration sources such as:

Reaction wheel assemblies
Control moment gyros
Cryocoolers
Stepping and scanning mechanisms

Sensitive Payload Isolation

Sometimes it is more practical to reduce vibration at one instrument, sensor, or payload. This may be because there are multiple vibration sources on the satellite or because that particular payload has extremely tight jitter specifications. Payloads that benefit from our vibration isolation include:

Imaging systems
Science instruments
Optical communication nodes

Vibration Dampers

When one or more resonances contribute significantly to jitter, a damper can reduce vibration for a specific payload or for the whole satellite bus. Our customers also use vibration dampers for low frequency modes, including those of solar arrays, to extend the bandwidth of attitude control systems.
