Mechanisms and temperature control

Airbus Crisa provides an extensive catalogue of solutions to manage the actuators and effectors required by space systems, from mechanisms control to temperature control, also including valves driving and pyrotechnic electronics.

Our mechanisms control products include Electric Motor Driving electronics for a wide variety of uses, such as scan electronics, control momentum gyro mechanisms and filter wheels.

Thermal control products are available for all types of spacecraft. Airbus Crisa offers solutions both for platforms and instruments, including specialized thermal control units such as cryogenic cooler electronics.

Temperature regulation

Airbus Crisa’s solutions for temperature control have been used on many types of spacecraft – from large telecommunications satellites to the iconic Orion space explorer that will transport astronauts to the Moon and beyond.

Key features of these units include the accurate measurement of temperature at many points within the spacecraft and the commanding of active and passive control systems. According to the needs of each system, Airbus Crisa applies different levels of intelligence – from pure slave to fully autonomous and programmable operation.

Cooler electronics

Drive electronic units

Many spacecraft instruments require for their operation to work at very low temperatures. To manage these systems, Airbus Crisa develops highly capable cooler drive electronic units, providing high levels of efficiency and performance.

For the primary types of cooler systems (Stirling Coolers and Pulse Tube Coolers), Airbus Crisa’s solutions offer such state-of-the-art features as micro-vibration cancellation, active filtering of electromagnetic interference (EMI) and the re-configurability of control algorithms.

Mechanisms

Control Momentum Gyroscope Electronics (CMG-E) and Scan Drive Electronics (SDE) are two of the products designed and developed by Airbus Crisa.

CMG-E is the unit in charge of driving the wheel and gimbal motors of Control Momentum Gyro (CMG) mechanisms for agile satellite attitude control.

Airbus Crisa also has developed electronic equipment that control and manage scanner and refocusing mechanism stepper motors.
