The Workshop on Simulation for European Space Programmes (SESP) has been organised by ESA on a bi-annual basis since 1990. In 2010, the scope of SESP was widened to include the subject areas of the closely associated Workshop on Electrical Ground Support Equipment (EGSE), which until then has been organized as a separate event since 1992. SESP became therefore the Workshop on Simulation and EGSE for Space Programmes.
