About
Dispenser systems are used for multiple satellite launches. This is especially suitable for spacecraft constellations where a number of spacecraft need to be placed in orbit in a short time frame. Beyond Gravity is a leading supplier with track record on programs such as Galileo, TerraBella, Radarsat Constellation, Amazon Leo and Eutelsat OneWeb.
A dispenser system includes the structure subsystem, the separation system, the electrical harness 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.
