ASTROFEIN one of the leading brands
in Reaction Wheels
Reaction wheels are used to control the attitude of satellites.
Since the first ASTROFEIN reaction wheels were launched in 2001 with the BIROS mission,
ASTROFEIN has established itself as a market leader in the development and production of reaction wheels.
The ASTROFEIN reaction wheel family comprises four classes,
addressing different satellite sizes and performances.

Innovativ
ASTROFEIN is one of the first companies worldwide to develop intelligent reaction wheels.
The intelligent reaction wheels perform tasks of control and monitoring,
which are part of the attitude control of satellites.
Experienced
ASTROFEIN has extensive know-how in the production,
development and testing of reaction wheel technologies.
Customer-focused
A scalable approach allows us to implement customer-specific wishes.
If you can’t find the performance you need for your mission in our standard wheels
– feel free to contact us.
Focused
The product range of ASTROFEIN Reaction Wheels
includes a CubeSat Line, SmallSat Line, Torque Line
and High Line, which serve different satellite sizes,
different orbits and performance requirements.
Precise
ASTROFEIN Reaction Wheels are highly functional.
With model-based controls achieve
ASTROFEIN’s intelligent Reaction Wheels achieve higher accuracies and stabilities.
The internal friction estimation leads to improved
reaction torque stability and repeatability.
In addition, the intelligent wheels operate very accurately even in the standstill range.
They automatically compensate for effects caused by time delay, instabilities
or violation of physical limits.
