Magnus Engström Senior Sales Manager Dispenser/Separation Systems

Beyond Gravity's separation systems securely hold satellites to their launch vehicles during the difficult journey to orbit and then precisely deliver the valuable payload to orbit at the specified relative velocity, potential spin or transverse spin. Our separation systems have an excellent flight record: To date more than 1200 in-orbit separations have been performed with a 100% success rate.

We offer standard and specialized systems for particular applications such as in-orbit separation of return-to-earth capsules, also including both clamp-band and hard-point separation systems. Our low-shock clamp-tape separation system is the industry standard for any payload. Our long-standing track-record gives launch vehicle operators and satellite builders as well as operators confidence in planning future missions with us.

Satellite dispenser systems

Dispenser systems are used for multiple satellite launches. This is especially suitable for spacecraft constellations where a number of spacecrafts need to be placed in orbit in a short time frame. We are a leading supplier with track record on programs such as Galileo, TerraBella, Radarsat Constellation and OneWeb. A dispenser system inlcude the structure subsystem, the separation system, the electrical herness as well as the thermal subsystem. At its lower interface the dispenser structure is bolted to the launch vehicle’s upper stage. Each spacecraft is attached to the dispenser in separation nodes.

Beyond Gravity dispensers provide a stiff connection in each node during launch, a safe release and an accurate separation provided by the separation nuts and spring units. The electrical harness consists of redundant umbilical cables to each spacecraft, a harness to the pyrotechnical initiators as well as an instrumentation harness. If required, we can equip our dispensers with our own power and sequencing electronics.

ESPA Separation System

The Beyond Gravity PSR 1575 mm (62”) separation system is fully compatible with the Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA). The PSR 1575 Separation System includes a low shock clamp band separation system, payload separation rings, umbilical connectors and a separation spring set. Utilizing our CBODTM Low Shock Release Mechanism every Beyond Gravity separation system provides the unique combination of high load capability and a low shock release.
