Vibration Isolations
for Spacecraft Instruments
STEP Lab provides launch and on-orbit vibration isolators for spaceborne payloads and component units.
Our isolators are superior in assuring both structural safety under harsh launch environment and vibrational stability against micro-vibration in on-orbit environment
Highlighted Features & Advantages
Launch Vibration Isolation
Launch vibration isolation of spacecraft on-board units without any additional launch locking mechanisms
Environment Mitigation
Availability of mitigating design and test requirements on the launch and on-orbit vibration environments
On-orbit Vibration Isolation
On-orbit micro-vibration isolation enables availability of applying sensitive payloads with minimal design efforts.
