MicroNed, reliability, radiation tolerance and Lens R&D

Delfi-C3 satellite related to the start of Lens R&D   Looking back at history the Dutch MicroNed technology development program has been instrumental in establishing Lens R&D. The program aimed at using MEMS technology to miniaturize satellite systems and led to the development of the Delfi-C3 satellite by the university of Delft in [...]

A new way of presenting the earlier data

Following the TRB we had for the GSTP program we are updating the gathered accuracy data representation. This, in order to make the high performance stability of our BiSon64-ET and BiSon64-ET-B sensors more visible. The shown graph shows the raw error data (so without corrections) before and after the qualification program that consisted of: humidity [...]
