Highly-Reliable Family of Separation Systems for Small Satellites
SAU&RON is a family of separation rings built for those small satellites that require a standard and reliable 8" or 15" interface to a launch vehicle.
Separation Adapter Unit & Ride-ON
SAU&RON is a family of separation rings built for those small satellites that require a standard and reliable 8" or 15" interface to a launch vehicle.
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.
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:
Total mass
Starting from 1.6 kg
Ride-ON mass (flyaway)
< 0.2 kg
* Lightweight version available for spacecraft with mass below 200 kilograms.
Rocket side ring interface
12 x 1/4 inch bolts, according to the 8-inches ESPA interface (or 12 x M6)
Payload side ring interface
12 x 1/4 inch bolts, according to the 8-inches ESPA interface (or 12 x M6)
Actuation response time
< 100 ms
Stack height
50.0 mm
Payload capacity
120 kg (250 mm CG height from rocket plane)
Unitary spring energy
0.025 to 3.7 Joules (Customizable to user needs)
Separation velocity
Customizable from 0.1 m/s to 0.8 m/s (mass dependant)
* The overall system mass can limit the maximum relative separation velocity.
Shock output
< 100 g's @ 1 kHz (Low shock)
* Value obtained by analysis. The final results are pending and will be confirmed after further testing.
Actuator type
Redundant space-grade DC motors
Actuator voltage
28V ±4V (typical)
Release signal
150 ms pulse with < 2 amps (typical)
Release time
150 ms max.
Data / Power / Grounding interface
15 pin, negative insertion force connector. Up to 3 A per pin
* Up to 4 connectors can be added around the ring. Typically they are used for grounding, power, and data separately.
