SESP 2025 Showcases the Latest Advances in Simulation and Verification of Space Systems

GMV participated in the 2025 edition of the Workshop on Simulation and EGSE for Space Programmes (SESP), an event organized by the European Space Agency (ESA) that has been held every two years since 1990. Established as a key forum for the design and verification of space systems, SESP brought together space agencies and industry experts to share experiences and analyze trends in simulation, functional verification, test benches, and EGSE environments.
Since 2010, the workshop has also covered topics related to Electrical Ground Support Equipment (EGSE), which has enabled synergies between disciplines that share common methodologies, standards, and tools.
GMV played an active role in this latest edition with technical contributions from Alejandro Antúnez, Technical Leader of the Operational Simulators and Space Modeling division, who presented the poster "SIMCRAFT©: A user-friendly, scriptable, and highly configurable generic satellite simulator based on SIMULUS," showcasing the features of the newly launched validation product for ground systems and control centers developed by GMV.
Leandro García, a project engineer in the same division, also participated by presenting the paper "Extending SIMULUS-based simulators with Digital Twin capabilities," which addressed recent advancements in the field of Digital Twins from the perspective of SIMULUS-based simulators.
Additionally, the event featured a live demonstration of HERASIM, the operational simulator of the HERA mission, which aims to analyze the first asteroid deflection experiment and conduct the first detailed study of a binary system. This demo was coordinated by ESOC’s Sim Officer, with technical support from GMV, which has developed the simulator.
