H2020 EDDA is one of the project of the Strategic Research Cluster (SRC) on “In-Space electrical propulsion and station keeping” ( and is also a continuation of H2020 HV-EPSA (grant 687515, which allowed to work on high voltage bus, from 300V to 600V, mandatory for direct-drive architecture.
H2020 CHEOPS (also part of the SRC, is developing Electrical Propulsion Subsystem for various power range missions, including a high-power Hall Effect Thruster (HET) of 20kW. A dedicated assessment is done for a direct-drive architecture for a specific HET called HT20k.

Hall Effect Thruster, as well as HEMP Thruster (developed in H2020 HEMPT-NG, part of theSRC, has a voltage range compatible to the high voltage bus studied in HV-EPSA H2020 EDDA will enable a transversal architecture compatible with various electric thrusters available on the market, allowing to enhance the global efficiency from solar array to thruster.

Numerous missions will benefit of this architecture:

  • Large telecom satellite with electric propulsion for orbit raising
  • In-orbit service mission
  • Interplanetary transportation
