Separation Systems.
Ensuring that the satellite and rocket remain securely connected during launch and that the payload is placed in orbit with precision.
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.
PAS 381S (15”) Separation System
The Beyond Gravity 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.
PAS 432S (17”) Separation System
The Beyond Gravity 432S Separation System is designed for a first application for satellites up to 200 kg @ 0.45 mm on the VEGA launch vehicle. 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.
PAS 610S (24”) Separation System
The load capability of the Beyond Gravity PAS 610S Separation System is fully compatible with the Moog CSA ESPA and environments from the ESPA Rideshare User’s Guide (ESPA Beyond Gravity).
Separation Nut PSM 1/2B
The Beyond Gravity PSM 1/2B Separation Nut is the medium member of our family of Low Shock Separation Nuts designed for interfacing medium sized spacecraft with Launcher Vehicles. It has been developed to fit constellation class satellites, typical 500-1000kg.
Separation Nut PSM 3/8B
The Beyond Gravity PSM 3/8B Separation Nut is the smallest member of our family of Low Shock Separation Nut designed for interfacing small sized spacecraft with Launcher Vehicles. It has been developed to fit the One Web™ class of satellites, typical 100-200kg.
Modular payload adapter systems
Beyond Gravity is the world's leading provider of payload adapter systems, the physical structure used to connect a payload to the launch vehicle. Our modular adapters allow compatibility with almost any satellite on the market for any launch vehicle. We are a supplier for Ariane, Atlas, Delta, Land Launch, Proton, Sea Launch, Soyuz and Antares launch vehicles and offer a wide range of payload adapter systems that are compatible with most of the satellite buses in use around the world today.
Our services include supporting our customers through all phases of the program, up to and including successful on-orbit separation of the satellite. Payload adapters are tailored to customer needs and manufactured from aluminum or carbon fiber composites to deliver impressive performance.
