reaching from the world’s smallest commercial reaction wheel RW 1 (10-4 Nms) to the RW 250 (4 Nms). The reaction wheels RW 90 and RW 1 are already flight proven. Four reaction wheels RW 90 come into operation at the small satellite TET-1 (launch in 2012).  State of the art feedback systems in combination with model based controller algorithms making smart reaction wheels the ideal solution for zero-momentum attitude control strategies because these reaction wheels will operate with high accuracy as well in the “low wheel speed region”. Astro- und Feinwerktechnik Adlershof GmbH

Test bed for rotational speed sensors. The test bed allows new combinations of measuring tasks. Therefore the sensors can be checked under different application scenarios.

Main functions:
• wide speed range
• high temperature loads
• Rotational vibrations of the code wheel
• maximum air gap
• air gap jumps
• free positioning of the sensors in four axes in relation to the code wheel
