Overview

The RUAG 381S Separation System is the smallest member of our family of Low Shock Separation Systems designed for interfacing small sized spacecraft with Launcher Vehicles. It has been developed to fit the ESPA 15" adapter interface.

The Separation System includes a low shock clamp band separation system, interface rings, umbilical connection and a separation spring set. With our CBOD-LT Separation System Release Mechanism we 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 RUAG. Developed for over 30 years, the RUAG Space product family to date includes a broad range of Separation Systems, spanning diameters from 381 mm to 2624 mm (15" to 103").

Our Separation Systems have an outstanding flight record. To date more than 630 in-orbit separations have been carried out with a success rate of 100%. Our customer base includes launch service providers, satellite builders, government entities and national space agencies. We work closely with the customers during the spacecraft design phase to establish a fully compatible design.
