About
The Beyond Gravity 381S Separation System is the smallest member of the family of Low Shock Separation Systems designed for interfacing small sized spacecraft with launch vehicles. It has been developed to fit the ESPA 15 in adapter interface.
The Separation System includes a low shock clamp band separation system, interface rings, umbilical connection and a separation spring set. With the CBOD-LT Separation System Release Mechanism, Beyond Gravity can provide the unique combination of high load capability and a low shock release.
The PAS 381S Separation System is based on the already flight proven systems at Beyond Gravity. Developed for over 30 years, the Beyond Gravity product family to date includes a broad range of Separation Systems, spanning diameters from 360 mm to 2624 mm (14 to 103 in). The Separation Systems have an outstanding flight record: to date more than 660 in-orbit separations have been carried out with a success rate of 100%. The customer base includes launch service providers, satellite builders, government entities and national space agencies.
