Electronics : Heritage

AMPACIMON

Three groups of Liège University : TDEE, EMMI and the CSL developped an innovative system for monitoring high voltage lines current carrying capacity. The autonomous system is based on vibration analysis techniques from TDEE. The system engineering was done at EMMI, the CSL electronics laboratory designed the on board electronics and took part in testing.

CRP

Electronic position contactless sensor

The CRP is a position detector for distribution valves in the booster actuators of the hydraulic circuit of ARIANE 5. The position is measured electromagnetically without contact through a high pressure wall, with an accuracy of 0.05 mm (response time < 20msec). This very sophisticated instrument was developed and built at CSL. It is now used on the first stage of ARIANE 5.

HM+

The objective of this project is to decrease the maintenance cost, representing today around 25 % of total airplane ownership cost. This is achieved by development of predictive maintenance (health monitoring). HM+ is funded by the Walloon Region in the frame of the SKYWIN aerospace cluster. In this frame, in collaboration with THALES ALENIA SPACE ETCA, a bench test for electrical arc fault generation is operational at CSL, providing a useful tool for test and validation of algorithms for arc fault detection.    more

 

JUNO 

CSL built a mechanism for this NASA mission to Jupiter. The mechanism is a scanning mirror actuated by a stepping motor. CSL electronics lab designed a motor controller and built a prototype, and american industry made a copy at flight standard. CSL integrated and tested the assembly.  more 

 

PHOTOMETER

The need for precision measurement of light intensity exists in all optical instrumentation projets. The CSL electronics laboratory has developped a high stability device, that allows monitoring the output of light sources used in all kinds of optical experiments. It has been used internally and by customers in test benches for earth observation satellite, sun simulators, reflectance measurements, etc...Its built-in noise averaging and temperature control features allow to reach a relative stability of better than 10-4 over one year.  more

 

PROBA V 

Proba V is a belgian mini-satellite designed for earth observation. Industrial companies KinetiQ Space made the platform, OIP the “Vegetation” instrument. The CSL was in charge of instrument testing and calibration and therefore assembled a  specific ground support equipment including light sources, collimator, motion controllers and measurement procedures.  more

 

SORMEN

Innovative Separation Method for Non-Ferrous Metal Waste from Electric and Electronic Equipment based on Multi- and Hyper- spectral Identification.
SORMEN is a pre-competitive FP6 research project for a two years development, whose objective is to develop a reliable technology in order to automate scrap processing in the recycling sector for nonferrous metals.
CSL team has collaborated on the instrument design with ROBOTIKER TECNALIA, INDUMETAL RECYCLING, ACLIMA, IGE HENNEMANN Recycling Gmbh, HEVAC AMBIANT GROUP and SPECIM, focusing its research on the illumination device of the setting-up. The project has been finalized in August 2008.

 

XMM

The XMM/Newton satellite contained 3 mirror assemblies for imaging the sky in X-ray wavelengths. The individual mirrors, and later the assembled satellite focal plane, were measured and tested at CSL. For that purpose it was necessary to build a complex test bench including X-ray sources and detectors, high voltage supplies, ultraviolet sources and cameras, positioning mechanisms, motion controllers, etc… The CSL electronics lab had to integrate the various components into a functioning and computer controlled architecture.   more
