During May GTD presented its LibmCS mathematical library during DASIA 2022 and ESTEC Final Presentation Days. In both events GTD could present the features of the fully ECSS Category-B qualified LibmCS mathematical library to a wide audience of the most relevant European space actors. This will ensure the use of the library by many future European spacecrafts and their instruments, wherever correct mathematical computing matters. DASIA 2022 is organized by ASD-EUROSPACE and the ESTEC final presentations days by ESA.
