Vibration Isolation Solutions
STEP Lab provides launch and on-orbit vibration isolator technologies for spacecraft system, payloads and instrument units.
Our isolator products has superior advantages in assuring both structural safety under harsh launch environment and vibrational stability against micro-vibration in on-orbit environment.
History & Heritage
Our first product supplied and flown to space was the “passive launch and on-orbit vibration isolator (PLOVIS)”.
This has been operated successfully in the spaceborne high resolution optical payloads of Korean 1st military spy satellite (EO/IR)
(TRL 9 reached).
This isolator was also supplied to the KOMPSAT-7 (EO/IR) and exported to the OHB systems AG (Germany) in 2021.
STEP Lab is leading company in spacecraft vibration isolation technologies based on a variety of products has been developed and supplied for spaceborne instruments, attitude control actuators and SmallSats.
Highlighted Features & Advantages
Vibrational Stability
Low-stiffness mount ensures vibration isolation performance, which leads to stability of the customer’s hardware.
Structural Safety
Our unique mechanical design ensures structural safety under severe launch vibration and shock loads.
Robust Performance
Performance insensitive to environmental conditions (e.g. temperature) than typical rubber mounts
Reliability
Reliability is realized by design simplicity (without additional launch lock device)
Cost-effective
Passive-type isolators are cost-effective, so that it could be effective solution for low-cost SmallSats.
Modification Availability
Isolator cut-off frequency can be changed by changing isolator elements based on customer’s need.
Available Products
Our product line includes the passive launch and on-orbit vibration isolators for for CubeSats, SmallSats, launch vehicle payload adapter and spacecraft on-board instrument units.
For Spacecraft Instruments
Vibration isolators applied to on-board instruments requiring launch vibration attenuation or high level of on-orbit vibrational stability against micro-vibration.
For CubeSat POD
Vibration isolators applied to CubeSat PODs for “whole cubesat vibration isolation” against harsh launch vibration & shock environment.
For SmallSat Ring Adapter
Vibration isolators applied to “whole satellite vibration isolation” against harsh launch vibration & shock environment.
For Launcher Payload Adapter
Vibration isolators for secondary payload adapter structures interfaced with launch vehicles for “multi-payloads vibration isolation” against harsh launch vibration & shock environment.
R&D Capability
STEP Lab is available to perform research and development of customer-dedicated vibration isolators based on our engineering capabilities and experiences.
