Description
Summary:	IPSIS (Intelligent Planetary SIte Selection) algorithm is an innovative autonomous, dynamic and adaptable fuzzy multi-criteria algorithm developed to choose the best candidate safe landing site for spacecraft, with hazard avoidance. In this article the evolving IPSIS structure is discussed within past ESA financed projects, as well as their achieved Technology Readiness Level (TRL). To achieve a higher TRL, an IPSIS-Modified version is presented regarding its implementation in real-time and hardware-acceleration with the use of Field-Programmable Gate Arrays (FPGAs) for parallel processing in conjunction with the chosen board's processing system. This modified version, with some trimmed and added modules, modifications and optimizations is discussed and the computational effort between the past and current IPSIS versions is compared using the same dataset from a precursor project.
