| Zusammenfassung | The MICROSCOPE (MicroSatellite à trainee Compensee pour l'Observation du Principe d'Equivalence ) project is an orbit-based mission to verify the Weak Equivalent Principle with an uncrtainty of 10-15. To achieve this goal two differential accelerometers, each equipped with two high precision test masses (made of PtRh10 and TiA16V4 in the form of hollow cylinders with four flats at the outer shell and six precision countersinks at each face), are to be launched in Spring 2016 and shall orbit the earth for approx. one and a half year. This paper describes the fundamental challenges of the test-mass fabrication on the basis of the requirements of the overall space project and the means developed to integrate in-situ measurement equipment into the precision fabrication station to link the internal probes to traceable standards. |
