Ion Thrusters


Airbus Crisa’s extensive experience in the design and development of electric propulsion power processing units covers the range of gridded ion thrusters from 700 V to 2.2 kV, backed by flight-proven high-voltage technology.

Cutting-edge power processing technology from Airbus Crisa delivers up to 6 kW to all power supplies required for thruster operation, including neutralizer, station-keeping, ignition, radio frequency generation  and flow control. Thruster control, fault and parameter configuration are provided as well.

As a result of Airbus Crisa’s modular approach, its power processing units are easily adaptable to the spacecraft’s electrical propulsion system needs.

Power for Active Antenna

Distributed Systems


Airbus Crisa is one of the leading developers of centralized power supply units for DC power solutions with active antennas.

Its unique centralized power and distribution solutions enable hundreds of amplifiers to be supplied via protecting elements with clean DC power – meeting the most demanding RF performance requirements.

With Airbus Crisa’s modular approach, centralized power supply units can cover a wide output power range from 1 kW to more than 10 kW, and are capable of being powered directly from the platform power bus.
