For spacecraft up to 450 kilograms

The SAU&RON family of separation systems offers an optimized mechanical design that allows attaching a spacecraft with the maximum mass supported by an ESPA adapter, making it the best separation system in terms of mass ratio.

With just 1.6 kilograms on its 8-in version and 2.9 kilograms on the 15-in version together with the use of redundant flight-proven motorized actuators, they offer low to no shock to the carried payload.

SAU&RON rings also allow customization on the separation velocity to meet customer's requirements on the precise deployment of payloads, making it ideal for critical LEO and interplanetary missions.

Highlighted Features

SAU&RON is a family of rings designed and built with reliability as one of the driving factors and prepared for Low Earth Orbit and interplanetary missions:

It uses highly-reliable flight-proven motorized actuators

Exceeds the mass limit imposed by an ESPA ring, allowing payloads weighting more than 450 kilograms, the best in class

Provides up to 60 lines of harness between the payload and the launch vehicle side, withstanding up to 3A each

It has an ITAR/EAR Free design

Complies with the REACH regulation
