ASTROFEIN – Precision in Space. The Berlin-based SME is one of the world's leading manufacturers of reaction wheels and produces the Ferrari among the CubeSat Deployers - the PSL.

About us

ASTROFEIN – Precision in Space. ASTROFEIN, a SME based in Berlin Germany, develops, produces and tests components and systems for space. We focus on small satellites, attitude control, structures, mechanisms and payloads. The comprehensive knowledge, expertise and experience of the employees ensure the highest quality.

ASTROFEIN is one of the world's leading manufacturers of reaction wheels. The ASTROFEIN RW Family can be categorized in 4 groups: CubeSatLine, SmallSat Line, Torque Line for SmallSats and a HighLine.
Our Reaction Wheel Family comprises at the current point in time 14 different wheels addressing different performance requirements and and thus satellite sizes and different orbits.

ASTROFEIN produces the Ferrari among the Deployer (to quote one of our customers) - our ASTROFEIN PicoSatellite Launcher (PSL). Our PSL family consists of the PSL1U, PSL2U, PSL3U, PSL6U, PSL6U XL, PSL12U, PSL12U XL and the PSL16U.

ASTROFEIN follows highest quality standards: Our processes are certified according to DIN EN 9100:2018.

ASTROFEIN Reaction Wheel Family

The Future is digital. ASTROFEIN’s Reaction Wheels are smart RWs. They relieve the attitude control data processing unit and the satellite’s attitude control engineering team. So, they are performing tasks that were so far part of the attitude control system of the satellite, tasks which are related to controlling and monitoring the reaction wheel.

ASTROFEIN’s smart RWs are characterized by
• A Digital interface
• An Internal monitoring and protective mechanism
• A Model based controller

ASTROFEIN PicoSatellite Launcher (PSL) Family

The ASTROFEIN PSL ensures:
• No tumbling
• No bouncing inside the dispenser
• Deployment initiated when the door is completely opened & locked (patented)
• User friendly system: easily resettable
• Redundancy in actuation & deployment confirmation signal
• Fixation of the CubeSat in X, Y and Z during launch (patented)
• Closed envelope: high safety
• Defined deployment energy & low spin rate
• Large clearance
• Access ports for maintenance on launch site
• Fully qualified technology

ASTROFEIN ACS Test Bed

Key Features:
• Free rotation about the vertical axis, 20° rotation about the two horizontal axes
