High Precision Dynamic Bench Test Facility for Attitude Control

The concept of the Dynamic Bench Test Facility is based on the combined operation of two high precision three-axis motion simulators, sensor stimulators (e.g. sun simulator) and a simulation computer system. Arranging motion simulators and sensor stimulators into specific geometrical configuration enables hardware-in-the loop simulations, material stress tests and sensor characterization and calibration.

The Dynamic Bench Test Facility at the Zentrum für Telematik provides therefore a broad range of test services to different industries including automotive, engineering and aerospace.

Especially to the new space environment, this unique high-precision facility offers verification and calibration of the attitude control system of small satellites. In particular, this facility enables verification and calibration on system-level, the fully integrated small satellites are mounted directly on the high-precision motion simulators for full HiL-Tests and calibration. Furthermore, verification and calibration of interacting multi-satellite systems with focus on formation control, relative navigation, inter-satellite communication links and cooperative target observation can be performed.
