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....

RUAG Space is the prime contractor and has the system responsibility for programs such as Galileo, TerraBella, Radarsat Constellation and OneWeb.

The major parts of the dispenser system are:

  • the structure subsystem
  • the separation system
  • the electrical harness
  • the thermal subsystem

At its lower interface the dispenser structure is bolted to the launch vehicle upper stage. Each spacecraft is attached to the dispenser in separation nodes. The RUAG dispenser provides a stiff connection in each node during launch, a safe release and an accurate separation provided by the four 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.

Sometimes we carry our own power and sequencing electronics.
