MLFS (Mathematical Library for Flight Software)


Timeframe: 2016-2018
Reengineering and qualification (on LEON2 and LEON4 prozessors) of a mthematical library according to ECSS (European Cooperation for Space Standardization) for the European Space Agency ESA.
MLFS contains fundamental mathematical functions and allows a simple reuse (qualification for a specific project) for space missins following ECSS. Future space projects such as EUCLID and VEGA-C will presumably use MLFS.
The library has been qualified by 4072 unit tests and 1013 validation tests. Additionally most 32-bit functions have been tested exhaustively for all input values.

In the follow-up study PRECAST (Portability, Reproducibility, and Exception Handling of Control Software on Host and Target Platforms) GTD has established guidelines to guarantee numerical reproducability between simulation environments and target platforms.
